uint8_t sdc_hci_cmd_cb_set_event_mask(const sdc_hci_cmd_cb_set_event_mask_t *p_params)

Set Event Mask.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.3.1

The HCI_Set_Event_Mask command is used to control which events are generated by the HCI for the Host. If the bit in the Event_Mask is set to a one, then the event associated with that bit will be enabled. For an LE Controller, the “LE Meta event” bit in the event_Mask shall enable or disable all LE events in the LE Meta event (see Section 7.7.65). The event mask allows the Host to control how much it is interrupted.

The Controller shall ignore those bits which are reserved for future use or represent events which it does not support. If the Host sets any of these bits to 1, the Controller shall act as if they were set to 0.

Event(s) generated (unless masked away): When the HCI_Set_Event_Mask command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_cb_reset(void)

Reset.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.3.2

The HCI_Reset command will reset the Controller and the Link Manager on the BR/EDR Controller or the Link Layer on an LE Controller. If the Controller supports both BR/EDR and LE then the HCI_Reset command shall reset the Link Manager, Baseband and Link Layer. The HCI_Reset command shall not affect the used HCI transport layer since the HCI transport layers may have reset mechanisms of their own. After the reset is completed, the current operational state will be lost, the Controller will enter standby mode and the Controller will automatically revert to the default values for the parameters for which default values are defined in the specification. Note: The HCI_Reset command will not necessarily perform a hardware reset. This is implementation defined. The Host shall not send additional HCI commands before the HCI_Command_Complete event related to the HCI_Reset command has been received.

Event(s) generated (unless masked away): When the reset has been performed, an HCI_Command_Complete event shall be generated.

Return values: 0 – if success.
Returns: Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_cb_read_transmit_power_level(const sdc_hci_cmd_cb_read_transmit_power_level_t *p_params, sdc_hci_cmd_cb_read_transmit_power_level_return_t *p_return)

Read Transmit Power Level.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.3.35

This command reads the values for the TX_Power_Level parameter for the specified Connection_Handle. The Connection_Handle shall be a Connection_Handle for an ACL connection

Event(s) generated (unless masked away): When the HCI_Read_Transmit_Power_Level command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.
p_return – [out] Extra return parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_cb_set_controller_to_host_flow_control(const sdc_hci_cmd_cb_set_controller_to_host_flow_control_t *p_params)

Set Controller To Host Flow Control.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.3.38

This command is used by the Host to turn flow control on or off for data and/or voice sent in the direction from the Controller to the Host. If flow control is turned off, the Host should not send the HCI_Host_Number_Of_Completed_Packets command. That command will be ignored by the Controller if it is sent by the Host and flow control is off. If flow control is turned on for HCI ACL Data packets and off for HCI Synchronous Data packets, HCI_Host_Number_Of_Completed_- Packets commands sent by the Host should only contain Connection_Handles for ACL connections. If flow control is turned off for HCI ACL Data packets and on for HCI Synchronous Data packets, HCI_Host_Number_Of_Completed_- Packets commands sent by the Host should only contain Connection_Handles for synchronous connections. If flow control is turned on for HCI ACL Data packets and HCI Synchronous Data packets, the Host will send HCI_Host_- Number_Of_Completed_Packets commands both for ACL connections and synchronous connections.

The Flow_Control_Enable parameter shall only be changed if no connections exist. Event(s) generated (unless masked away): When the HCI_Set_Controller_To_Host_Flow_Control command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_cb_host_buffer_size(const sdc_hci_cmd_cb_host_buffer_size_t *p_params)

Host Buffer Size.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.3.39

The HCI_Host_Buffer_Size command is used by the Host to notify the Controller about the maximum size of the data portion of HCI ACL and Synchronous Data packets sent from the Controller to the Host. The Controller shall segment the data to be transmitted from the Controller to the Host according to these sizes, so that the HCI Data packets will contain data with up to these sizes. The HCI_Host_Buffer_Size command also notifies the Controller about the total number of HCI ACL and Synchronous Data packets that can be stored in the data buffers of the Host. If flow control from the Controller to the Host is turned off, and the HCI_Host_Buffer_Size command has not been issued by the Host, this means that the Controller will send HCI Data packets to the Host with any lengths the Controller wants to use, and it is assumed that the data buffer sizes of the Host are unlimited. If flow control from the Controller to the Host is turned on, the HCI_Host_Buffer_Size command shall after a power-on or a reset always be sent by the Host before the first HCI_Host_Number_Of_Completed_Packets command is sent.

The Set Controller To Host Flow Control command is used to turn flow control on or off. The Host_ACL_Data_Packet_Length command parameter will be used to determine the size of the L2CAP segments contained in ACL Data packets, which are transferred from the Controller to the Host. The Host_Synchronous_Data_Packet_Length command parameter is used to determine the maximum size of HCI Synchronous Data packets. Both the Host and the Controller shall support command and event packets, where the data portion (excluding header) contained in the packets is 255 octets in size.

The Host_Total_Num_ACL_Data_Packets command parameter contains the total number of HCI ACL Data packets that can be stored in the data buffers of the Host. The Controller will determine how the buffers are to be divided between different Connection_Handles. The Host_Total_Num_Synchronous_ Data_Packets command parameter gives the same information for HCI Synchronous Data packets.

Note: The Host_ACL_Data_Packet_Length and Host_Synchronous_Data_ Packet_Length command parameters do not include the length of the HCI Data packet header.

Event(s) generated (unless masked away): When the HCI_Host_Buffer_Size command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_cb_host_number_of_completed_packets(const sdc_hci_cmd_cb_host_number_of_completed_packets_t *p_params)

Host Number Of Completed Packets.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.3.40

The HCI_Host_Number_Of_Completed_Packets command is used by the Host to indicate to the Controller the number of HCI Data packets that have been completed for each Connection_Handle since the previous HCI_Host_- Number_Of_Completed_Packets command was sent to the Controller. This means that the corresponding buffer space has been freed in the Host and is available for new packets to be sent. Based on this information, and the Host_Total_Num_ACL_Data_Packets and Host_Total_Num_Synchronous_- Data_Packets command parameters of the HCI_Host_Buffer_Size command, the Controller can determine for which Connection_Handles the following HCI Data packets should be sent to the Host. When the Host has completed one or more HCI Data packet(s) it shall send an HCI_Host_Number_Of_Completed_- Packets command to the Controller, until it finally reports that all pending HCI Data packets have been completed. The frequency at which this command is sent is manufacturer specific.

The Set Controller To Host Flow Control command is used to turn flow control on or off. If flow control from the Controller to the Host is turned on, the HCI_Host_- Buffer_Size command shall always be sent by the Host after a power-on or a reset before the first HCI_Host_Number_Of_Completed_Packets command is sent.

The HCI_Host_Number_Of_Completed_Packets command may be sent at any time by the Host when there is at least one connection, or if the Controller is in local loopback mode, independent of other commands. If the Host issues this command when neither of these cases applies, the Controller shall ignore it.

Event(s) generated (unless masked away): Normally, no event is generated after the HCI_Host_Number_Of_Completed_- Packets command has completed. However, if the HCI_Host_Number_Of_- Completed_Packets command contains one or more invalid parameters, the Controller shall return an HCI_Command_Complete event containing the error code Invalid HCI Command Parameters (0x12). The normal flow control for commands is not used for this command.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_cb_set_event_mask_page_2(const sdc_hci_cmd_cb_set_event_mask_page_2_t *p_params)

Set Event Mask Page 2.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.3.69

The HCI_Set_Event_Mask_Page_2 command is used to control which events are generated by the HCI for the Host. The Event_Mask_Page_2 is a logical extension to the Event_Mask parameter of the HCI_Set_Event_Mask command. If the bit in the Event_Mask_Page_2 is set to a one, then the event associated with that bit shall be enabled. The event mask allows the Host to control how much it is interrupted.

The Controller shall ignore those bits which are reserved for future use or represent events which it does not support. If the Host sets any of these bits to 1, the Controller shall act as if they were set to 0.

Event(s) generated (unless masked away): When the HCI_Set_Event_Mask_Page_2 command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Write Authenticated Payload Timeout.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.3.94

This command writes the Authenticated_Payload_Timeout (authenticatedPayloadTO, see [Vol 2] Part B, Appendix B and [Vol 6] Part B, Section 5.4 for the LE connection) parameter in the Controller for the specified Connection_Handle.

When the Connection_Handle identifies a BR/EDR ACL connection: • If the connection is in Sniff mode, the Authenticated_Payload_Timeout shall be equal to or greater than Tsniff. • If the connection is in Sniff Subrating mode, the Authenticated_Payload_Timeout shall be equal to or greater than (max subrate)xTsniff. • If the connection is in Hold mode, the Authenticated_Payload_Timeout shall be equal to or greater than the holdTO value.

uint8_t sdc_hci_cmd_le_read_buffer_size(sdc_hci_cmd_le_read_buffer_size_return_t *p_return)

LE Read Buffer Size [v1].

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.2

This command is used to read the maximum size of the data portion of ACL data packets and isochronous data packets sent from the Host to the Control- ler. The Host shall segment the data transmitted to the Controller according to these values so that the HCI ACL Data packets and HCI ISO Data packets will contain data up to this size. The HCI_LE_Read_Buffer_Size command also returns the total number of HCI LE ACL Data packets and isochronous data packets that can be stored in the data buffers of the Controller. The HCI_LE_- Read_Buffer_Size command shall be issued by the Host before it sends any data to an LE Controller (see Section 4.1.1). If the Controller supports HCI ISO Data packets, it shall return non-zero values for the ISO_Data_Packet_Length and Total_Num_ISO_Data_Packets parameters.

If the Controller returns a length value of zero for ACL data packets, the Host shall use the HCI_Read_Buffer_Size command to determine the size of the data buffers (shared between BR/EDR and LE transports).

Note: Both the HCI_Read_Buffer_Size command and the HCI_LE_Read_- Buffer_Size command may return buffer length and number of packets param- eter values that are nonzero. This allows a Controller to offer different buffers and number of buffers for BR/EDR data packets and LE data packets.

The LE_ACL_Data_Packet_Length return parameter shall be used to deter- mine the maximum size of the L2CAP PDU segments that are contained in ACL data packets, and which are transferred from the Host to the Controller to be broken up into packets by the Link Layer. The Total_Num_LE_ACL_Data_- Packets return parameter contains the total number of HCI ACL Data packets that can be stored in the data buffers of the Controller. The Host determines how to divide the buffers between different connection handles.

The ISO_Data_Packet_Length return parameter shall be used to determine the maximum size of the SDU segments that are contained in isochronous data packets, and which are transferred from the Host to the Controller. The Total_Num_ISO_Data_Packets return parameter contains the total number of isochronous data packets that can be stored in the data buffers of the Controller. The Host determines how to divide the buffers between different connection handle(s).

Note: The LE_ACL_Data_Packet_Length and ISO_Data_Packet_Length return parameters do not include the length of the HCI ACL Data packet header or the HCI ISO Data packet header respectively.

Event(s) generated (unless masked away): When the HCI_LE_Read_Buffer_Size command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_return – [out] Extra return parameters.

Return values

0 – if success.

LE Set Random Address.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.4

The HCI_LE_Set_Random_Address command is used by the Host to set the LE Random Device Address in the Controller (see [Vol 6] Part B, Section 1.3).

If this command is used to change the address, the new random address shall take effect for advertising no later than the next successful HCI_LE_Set_- Advertising_Enable command, for scanning no later than the next successful HCI_LE_Set_Scan_Enable command or HCI_LE_Set_Extended_Scan_- Enable command, and for initiating no later than the next successful HCI_LE_- Create_Connection command or HCI_LE_Extended_Create_Connection command.

Note: If the extended advertising commands are in use, this command only affects the address used for scanning and initiating. The addresses used for advertising are set by the HCI_LE_Set_Advertising_Set_Random_Address command (see Section 7.8.52).

If the Host issues this command when any of advertising (created using legacy advertising commands), scanning, or initiating are enabled, the Controller shall return the error code Command Disallowed (0x0C).

The HCI_LE_Set_Advertising_Parameters command is used by the Host to set the advertising parameters.

The Advertising_Interval_Min shall be less than or equal to the Advertising_Interval_Max. The Advertising_Interval_Min and Advertising_Interval_Max should not be the same value to enable the Controller to determine the best advertising interval given other activities.

For high duty cycle directed advertising, i.e. when Advertising_Type is 0x01 (ADV_DIRECT_IND, high duty cycle), the Advertising_Interval_Min and Advertising_Interval_Max parameters are not used and shall be ignored.

The Advertising_Type is used to determine the packet type that is used for advertising when advertising is enabled.

Own_Address_Type parameter indicates the type of address being used in the advertising packets.

If Own_Address_Type equals 0x02 or 0x03, the Peer_Address parameter contains the peer’s Identity Address and the Peer_Address_Type parameter contains the Peer’s Identity Type (i.e. 0x00 or 0x01). These parameters are used to locate the corresponding local IRK in the resolving list; this IRK is used to generate the own address used in the advertisement.

If directed advertising is performed, i.e. when Advertising_Type is set to 0x01 (ADV_DIRECT_IND, high duty cycle) or 0x04 (ADV_DIRECT_IND, low duty cycle mode), then the Peer_Address_Type and Peer_Address shall be valid.

If Own_Address_Type equals 0x02 or 0x03, the Controller generates the peer’s Resolvable Private Address using the peer’s IRK corresponding to the peer’s Identity Address contained in the Peer_Address parameter and peer’s Identity Address Type (i.e. 0x00 or 0x01) contained in the Peer_Address_Type parameter. The Advertising_Channel_Map is a bit field that indicates the advertising channel indices that shall be used when transmitting advertising packets. At least one channel bit shall be set in the Advertising_Channel_Map parameter.

The Advertising_Filter_Policy parameter shall be ignored when directed advertising is enabled.

The Host shall not issue this command when advertising is enabled in the Controller; if it is the Command Disallowed error code shall be used.

If the advertising interval range provided by the Host (Advertising_Interval_Min, Advertising_Interval_Max) is outside the advertising interval range supported by the Controller, then the Controller shall return the Unsupported Feature or Parameter Value (0x11) error code.

Event(s) generated (unless masked away): When the HCI_LE_Set_Advertising_Parameters command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_read_adv_physical_channel_tx_power(sdc_hci_cmd_le_read_adv_physical_channel_tx_power_return_t *p_return)

LE Read Advertising Physical Channel Tx Power.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.6

The HCI_LE_Read_Advertising_Physical_Channel_Tx_Power command is used by the Host to read the transmit power level used for LE advertising physical channel packets.

Event(s) generated (unless masked away): When the HCI_LE_Read_Advertising_Physical_Channel_Tx_Power command has completed, an HCI_Command_Complete event shall be generated.

LE Set Advertising Data.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.7

The HCI_LE_Set_Advertising_Data command is used to set the data used in advertising packets that have a data field. Only the significant part of the Advertising_Data should be transmitted in the advertising packets, as defined in [Vol 3] Part C, Section 11. If advertising is currently enabled, the Controller shall use the new data in subsequent advertising events. If an advertising event is in progress when this command is issued, the Controller may use the old or new data for that event. If advertising is currently disabled, the data shall be kept by the Controller and used once advertising is enabled.

Event(s) generated (unless masked away): When the HCI_LE_Set_Advertising_Data command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_scan_response_data(const sdc_hci_cmd_le_set_scan_response_data_t *p_params)

LE Set Scan Response Data.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.8

This command is used to provide data used in Scanning Packets that have a data field.

Only the significant part of the Scan_Response_Data should be transmitted in the Scanning Packets, as defined in [Vol 3] Part C, Section 11.

If advertising is currently enabled, the Controller shall use the new data in subsequent advertising events. If an advertising event is in progress when this command is issued, the Controller may use the old or new data for that event. If advertising is currently disabled, the data shall be kept by the Controller and used once advertising is enabled.

Event(s) generated (unless masked away): When the HCI_LE_Set_Scan_Response_Data command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_adv_enable(const sdc_hci_cmd_le_set_adv_enable_t *p_params)

LE Set Advertising Enable.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.9

The HCI_LE_Set_Advertising_Enable command is used to request the Con- troller to start or stop advertising. The Controller manages the timing of adver- tisements as per the advertising parameters given in the HCI_LE_Set_Advertising_Parameters command.

The Controller shall continue advertising until the Host issues an HCI_LE_- Set_Advertising_Enable command with Advertising_Enable set to 0x00 (Advertising is disabled). a connection is created using the advertising, or the Advertising is timed out due to high duty cycle Directed Advertising. In these cases, advertising is then disabled.

If Advertising_Enable is set to 0x01, the advertising parameters’ Own_- Address_Type parameter is set to 0x00, and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12).

If Advertising_Enable is set to 0x01, the advertising parameters’ Own_- Address_Type parameter is set to 0x01, and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If Advertising_Enable is set to 0x01, the advertising parameters’ Own_- Address_Type parameter is set to 0x02, the Controller’s resolving list did not contain a matching entry, and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12).

If Advertising_Enable is set to 0x01, the advertising parameters’ Own_- Address_Type parameter is set to 0x03, the controller’s resolving list did not contain a matching entry, and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters.(0x12).

Enabling advertising when it is already enabled can cause the random address to change. Disabling advertising when it is already disabled has no effect.

Event(s) generated (unless masked away): When the HCI_LE_Set_Advertising_Enable command has completed, an HCI_Command_Complete event shall be generated.

If the Advertising_Type parameter is 0x01 (ADV_DIRECT_IND, high duty cycle) and the directed advertising fails to create a connection, an HCI_LE_Connection_Complete or HCI_LE_Enhanced_Connection_Complete event shall be generated with the Status code set to Advertising Timeout (0x3C).

If the Advertising_Type parameter is 0x00 (ADV_IND), 0x01 (ADV_DIRECT_- IND, high duty cycle), or 0x04 (ADV_DIRECT_IND, low duty cycle) and a connection is created, an HCI_LE_Connection_Complete or HCI_LE_- Enhanced_Connection_Complete event shall be generated.

Note: There is a possible race condition if the Advertising_Enable parameter is set to 0x00 (Disable) and the Advertising_Type parameter is 0x00, 0x01, or 0x04. The advertisements might not be stopped before a connection is created, and therefore both the HCI_Command_Complete event and either an HCI_LE_Connection_Complete event or an HCI_LE_Enhanced_Connection_- Complete event could be generated. This can also occur when high duty cycle directed advertising is timed out and this command disables advertising.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_scan_params(const sdc_hci_cmd_le_set_scan_params_t *p_params)

LE Set Scan Parameters.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.10

The HCI_LE_Set_Scan_Parameters command is used to set the scan parameters.

The LE_Scan_Type parameter controls the type of scan to perform.

The LE_Scan_Interval and LE_Scan_Window parameters are recommenda- tions from the Host on how long (LE_Scan_Window) and how frequently (LE_Scan_Interval) the Controller should scan (See [Vol 6] Part B, Section 4.4.3). The LE_Scan_Window parameter shall always be set to a value smaller or equal to the value set for the LE_Scan_Interval parameter. If they are set to the same value scanning should be run continuously.

Own_Address_Type parameter indicates the type of address being used in the scan request packets.

The Host shall not issue this command when scanning is enabled in the Controller; if it is the Command Disallowed error code shall be used.

Event(s) generated (unless masked away): When the HCI_LE_Set_Scan_Parameters command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_scan_enable(const sdc_hci_cmd_le_set_scan_enable_t *p_params)

LE Set Scan Enable.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.11

The HCI_LE_Set_Scan_Enable command is used to start and stop scanning for legacy PDUs (but not extended PDUs, even if the device supports extended advertising). Scanning is used to discover advertising devices nearby.

The Filter_Duplicates parameter controls whether the Link Layer should filter out duplicate advertising reports (Filtering_Enabled) to the Host, or if the Link Layer should generate advertising reports for each packet received (Filtering_Disabled). See [Vol 6] Part B, Section 4.4.3.5. If LE_Scan_Enable is set to 0x00 then Filter_Duplicates shall be ignored.

If LE_Scan_Enable is set to 0x01, the scanning parameters’ Own_Address_- Type parameter is set to 0x00 or 0x02, and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12).

If LE_Scan_Enable is set to 0x01, the scanning parameters’ Own_Address_- Type parameter is set to 0x01 or 0x03, and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the LE_Scan_Enable parameter is set to 0x01 and scanning is already enabled, any change to the Filter_Duplicates setting shall take effect.

Disabling scanning when it is disabled has no effect.

Event(s) generated (unless masked away): When the HCI_LE_Set_Scan_Enable command has completed, an HCI_Command_Complete event shall be generated.

Zero or more HCI_LE_Advertising_Report events are generated by the Controller based on legacy advertising packets received and the duplicate filtering. More than one advertising packet may be reported in each HCI_LE_Advertising_Report event. No report shall be issued for extended advertising PDUs.

When the Scanning_Filter_Policy is set to 0x02 or 0x03 (see Section 7.8.10) and a directed advertisement was received where the advertiser used a resolvable private address which the Controller is unable to resolve, an HCI_LE_Directed_Advertising_Report event shall be generated instead of an HCI_LE_Advertising_Report event.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_create_conn(const sdc_hci_cmd_le_create_conn_t *p_params)

LE Create Connection.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.12

The HCI_LE_Create_Connection command is used to create an ACL connection, with the local device in the Central role, to a connectable advertiser. If a connection is created with the local device in the Peripheral role while this command is pending, then this command remains pending.

The LE_Scan_Interval and LE_Scan_Window parameters are recommenda- tions from the Host on how long (LE_Scan_Window) and how frequently (LE_Scan_Interval) the Controller should scan. The LE_Scan_Window param- eter shall be set to a value smaller or equal to the value set for the LE_Scan_- Interval parameter. If both are set to the same value, scanning should run continuously. The Initiator_Filter_Policy is used to determine whether the Filter Accept List is used. If the Filter Accept List is not used, the Peer_Address_Type and the Peer_Address parameters specify the address type and address of the advertising device to connect to. Peer_Address_Type parameter indicates the type of address used in the connectable advertisement sent by the peer. The Host shall not set Peer_Address_Type to either 0x02 or 0x03 if both the Host and the Controller support the HCI_LE_Set_Privacy_Mode command. If a Controller that supports the HCI_LE_Set_Privacy_Mode command receives the HCI_LE_Create_Connection command with Peer_Address_Type set to either 0x02 or 0x03, it may use either device privacy mode or network privacy mode for that peer device. Peer_Address parameter indicates the Peer’s Public Device Address, Random (static) Device Address, Non-Resolvable Private Address or Resolvable Private Address depending on the Peer_Address_Type parameter. Own_Address_Type parameter indicates the type of address being used in the connection request packets. The Connection_Interval_Min and Connection_Interval_Max parameters define the minimum and maximum allowed connection interval. The Connection_Interval_Min parameter shall not be greater than the Connection_Interval_Max parameter. The Max_Latency parameter defines the maximum allowed Peripheral latency (see [Vol 6] Part B, Section 4.5.1). The Supervision_Timeout parameter defines the link supervision timeout for the connection. The Supervision_Timeout in milliseconds shall be larger than (1 + Max_Latency) * Connection_Interval_Max * 2, where Connection_Interval_Max is given in milliseconds. (See [Vol 6] Part B, Section 4.5.2). The Min_CE_Length and Max_CE_Length parameters provide the Controller with the expected minimum and maximum length of the connection events. The Min_CE_Length parameter shall be less than or equal to the Max_CE_Length parameter. The Controller is not required to use these values. If the Host issues this command when another HCI_LE_Create_Connection command is pending in the Controller, the Controller shall return the error code Command Disallowed (0x0C).

If the Own_Address_Type parameter is set to 0x00 and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12). If the Own_Address_Type parameter is set to 0x01 and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12). If the Own_Address_Type parameter is set to 0x02, the Initiator_Filter_Policy parameter is set to 0x00, the Controller’s resolving list did not contain a matching entry, and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12). If the Own_Address_Type parameter is set to 0x02, the Initiator_Filter_Policy parameter is set to 0x01, and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12). If the Own_Address_Type parameter is set to 0x03, the Initiator_Filter_Policy parameter is set to 0x00, the controller’s resolving list did not contain a matching entry, and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12). If the Own_Address_Type parameter is set to 0x03, the Initiator_Filter_Policy parameter is set to 0x01, and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

Event(s) generated (unless masked away): When the Controller receives the HCI_LE_Create_Connection command, the Controller sends the HCI_Command_Status event to the Host. An HCI_LE_- Connection_Complete or HCI_LE_Enhanced_Connection_Complete event shall be generated when a connection is created because of this command or the connection creation procedure is cancelled; until one of these events is generated, the command is considered pending. If a connection is created and the Controller supports the LE Channel Selection Algorithm #2 feature, this event shall be immediately followed by an HCI_LE_Channel_Selection_- Algorithm event.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_create_conn_cancel(void)

LE Create Connection Cancel.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.13

The HCI_LE_Create_Connection_Cancel command is used to cancel the HCI_LE_Create_Connection or HCI_LE_Extended_Create_Connection commands.

If no HCI_LE_Create_Connection or HCI_LE_Extended_Create_Connection command is pending, then the Controller shall return the error code Command Disallowed (0x0C).

Event(s) generated (unless masked away): When the HCI_LE_Create_Connection_Cancel command has completed, an HCI_Command_Complete event shall be generated.

If the cancellation was successful then, after the HCI_Command_Complete event for the HCI_LE_Create_Connection_Cancel command, either an LE Connection Complete or an HCI_LE_Enhanced_Connection_Complete event shall be generated. In either case, the event shall be sent with the error code Unknown Connection Identifier (0x02).

Return values: 0 – if success.
Returns: Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

LE Add Device To Filter Accept List.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.16

The HCI_LE_Add_Device_To_Filter_Accept_List command is used to add a single device to the Filter Accept List stored in the Controller.

This command shall not be used when: • any advertising filter policy uses the Filter Accept List and advertising is enabled, • the scanning filter policy uses the Filter Accept List and scanning is enabled, or • the initiator filter policy uses the Filter Accept List and an HCI_LE_Create_Connection or HCI_LE_Extended_Create_Connection command is pending.

When a Controller cannot add a device to the Filter Accept List because there is no space available, it shall return the error code Memory Capacity Exceeded (0x07).

If the device is already in the Filter Accept List, the Controller should not add the device to the Filter Accept List again and should return success.

Address shall be ignored when Address_Type is set to 0xFF.

LE Connection Update.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.18

The HCI_LE_Connection_Update command is used to change the ACL connection parameters. This command may be issued on both the Central and Peripheral.

The Connection_Interval_Min and Connection_Interval_Max parameters are used to define the minimum and maximum allowed connection interval. The Connection_Interval_Min parameter shall not be greater than the Connection_Interval_Max parameter.

The Max_Latency parameter shall define the maximum allowed Peripheral latency.

The Supervision_Timeout parameter shall define the link supervision timeout for the LE link. The Supervision_Timeout in milliseconds shall be larger than (1

Max_Latency) × Subrate_Factor × Connection_Interval_Max × 2, where Connection_Interval_Max is given in milliseconds and Subrate_Factor is the current subrate factor of the connection.

The Min_CE_Length and Max_CE_Length are information parameters providing the Controller with a hint about the expected minimum and maximum length of the connection events. The Min_CE_Length shall be less than or equal to the Max_CE_Length.

The actual parameter values selected by the Link Layer may be different from the parameter values provided by the Host through this command.

If this command completes successfully and the connection interval has changed, then the subrating factor shall be set to 1 and the continuation number to 0. In this case, Max_Latency must be interpreted in underlying connection events. Otherwise the subrating factor and continuation number shall be unchanged and Max_Latency must be interpreted in subrated events.

Event(s) generated (unless masked away): When the Controller receives the HCI_LE_Connection_Update command, the Controller sends the HCI_Command_Status event to the Host. The HCI_LE_- Connection_Update_Complete event shall be generated after the connection parameters have been applied by the Controller or if the command subsequently fails.

Note: An HCI_Command_Complete event is not sent by the Controller to indicate that this command has been completed. Instead, the HCI_LE_- Connection_Update_Complete event indicates that this command has been completed.

Parameters

LE Read Channel Map.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.20

The HCI_LE_Read_Channel_Map command returns the current Channel_Map for the specified Connection_Handle. The returned value indicates the state of the Channel_Map specified by the last transmitted or received Channel_Map (in a CONNECT_IND or LL_CHANNEL_MAP_IND message) for the specified Connection_Handle, regardless of whether the Central has received an acknowledgment. If the connection handle does not identify an ACL connection, the Controller shall reject the command and should return the error code Unknown Connection Identifier (0x02).

uint8_t sdc_hci_cmd_le_read_remote_features(const sdc_hci_cmd_le_read_remote_features_t *p_params)

LE Read Remote Features.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.21

This command requests, from the remote device identified by the Connection_Handle, the features used on the connection and the features supported by the remote device. For details see [Vol 6] Part B, Section 4.6.

This command may be issued on both the Central and Peripheral.

Note: If a connection already exists between the two devices and the features have already been fetched on that connection, the Controller may use a cached copy of the features.

Event(s) generated (unless masked away): When the Controller receives the HCI_LE_Read_Remote_Features command, the Controller shall send the HCI_Command_Status event to the Host. When the Controller has completed the procedure to determine the remote features or has determined that it will be using a cached copy, the Controller shall send an HCI_LE_Read_Remote_Features_Complete event to the Host.

The HCI_LE_Read_Remote_Features_Complete event contains the status of this command and the parameter describing the features used on the connection and the features supported by the remote device.

Note: An HCI_Command_Complete event is not sent by the Controller to indicate that this command has been completed. Instead, the HCI_LE_Read_- Remote_Features_Complete event indicates that this command has been completed.

Parameters

p_params – [in] Input parameters.

Return values

The HCI_LE_Set_Default_PHY command allows the Host to specify its preferred values for the transmitter PHY and receiver PHY to be used for all subsequent connections over the LE transport.

The All_PHYs parameter is a bit field that allows the Host to specify, for each direction, whether it has no preference among the PHYs that the Controller supports in a given direction or whether it has specified particular PHYs that it prefers in the TX_PHYs or RX_PHYs parameter.

The TX_PHYs parameter is a bit field that indicates the transmitter PHYs that the Host prefers the Controller to use. If the All_PHYs parameter specifies that the Host has no preference, the TX_PHYs parameter shall be ignored; otherwise at least one bit shall be set to 1.

The RX_PHYs parameter is a bit field that indicates the receiver PHYs that the Host prefers the Controller to use. If the All_PHYs parameter specifies that the Host has no preference, the RX_PHYs parameter shall be ignored; otherwise at least one bit shall be set to 1.

If the Host sets, in the TX_PHYs or RX_PHYs parameter, a bit for a PHY that the Controller does not support, including a bit that is reserved for future use, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

If the Controller does not support asymmetric connections (see [Vol 6] Part B, Section 4.6.9.1) and the Host sets All_PHYs to 0x00 and TX_PHYs to a different value than RX_PHYs, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

uint8_t sdc_hci_cmd_le_set_phy(const sdc_hci_cmd_le_set_phy_t *p_params)

LE Set PHY.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.49

The HCI_LE_Set_PHY command is used to set the PHY preferences for the connection identified by the Connection_Handle. The Controller might not be able to make the change (e.g. because the peer does not support the requested PHY) or may decide that the current PHY is preferable (e.g., because it could not schedule other activities if the requested PHY was used or because it requires a PHY that supports Constant Tone Extensions).

The All_PHYs parameter is a bit field that allows the Host to specify, for each direction, whether it has no preference among the PHYs that the Controller supports in a given direction or whether it has specified particular PHYs that it prefers in the TX_PHYs or RX_PHYs parameter.

The TX_PHYs parameter is a bit field that indicates the transmitter PHYs that the Host prefers the Controller to use. If the All_PHYs parameter specifies that the Host has no preference, the TX_PHYs parameter shall be ignored; otherwise at least one bit shall be set to 1.

The RX_PHYs parameter is a bit field that indicates the receiver PHYs that the Host prefers the Controller to use. If the All_PHYs parameter specifies that the Host has no preference, the RX_PHYs parameter shall be ignored; otherwise at least one bit shall be set to 1.

If, for at least one direction, the Host has specified a preference and the current PHY is not one of those preferred, the Controller shall request a change. Otherwise the Controller may, but need not, request a change.

The PHY preferences provided by the HCI_LE_Set_PHY command override those provided via the HCI_LE_Set_Default_PHY command (Section 7.8.48) or any preferences previously set using the HCI_LE_Set_PHY command on the same connection.

The PHY_Options parameter is a bit field that allows the Host to specify options for PHYs. The default value for a new connection shall be all zero bits. The Controller may override any preferred coding for transmitting on the LE Coded PHY. The Host may specify a preferred coding even if it prefers not to use the LE Coded transmitter PHY since the Controller may override the PHY preference.

If the Host sets, in the TX_PHYs or RX_PHYs parameter, a bit for a PHY that the Controller does not support, including a bit that is reserved for future use, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

If the Controller does not support asymmetric connections (see [Vol 6] Part B, Section 4.6.9.1) and the Host sets All_PHYs to 0x00 and TX_PHYs to a different value than RX_PHYs, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

Event(s) generated (unless masked away): When the Controller receives the HCI_LE_Set_PHY command, the Controller shall send the HCI_Command_Status event to the Host. The HCI_LE_PHY_- Update_Complete event shall be generated either when one or both PHY changes or when the Controller determines that neither PHY will change immediately.

Note: If the peer negotiation resulted in no change to either PHY, this is not an error and the HCI_LE_PHY_Update_Complete event will contain a status indicating success.

Note: An HCI_Command_Complete event is not sent by the Controller to indicate that this command has been completed. Instead, the HCI_LE_PHY_- Update_Complete event indicates that this command has been completed. The HCI_LE_PHY_Update_Complete event may also be issued autonomously by the Link Layer.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

LE Set Advertising Set Random Address.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.52

The HCI_LE_Set_Advertising_Set_Random_Address command is used by the Host to set the random device address specified by the Random_Address parameter. This address is used in the Controller (see [Vol 6] Part B, Section 1.3.2) for the advertiser’s address contained in the advertising PDUs for the advertising set specified by the Advertising_Handle parameter.

This command may be issued at any time after an advertising set identified by the Advertising_Handle parameter has been created using the HCI_LE_Set_- Extended_Advertising_Parameters command (see Section 7.8.53). However, if the Host issues this command while the advertising set identified by the Advertising_Handle parameter is using connectable advertising and is enabled, the Controller shall return the error code Command Disallowed (0x0C).

If this command is used to change the address, the new random address shall take effect for advertising no later than the next successful HCI_LE_- Extended_Set_Advertising_Enable command and for periodic advertising no later than the next successful HCI_LE_Periodic_Advertising_Enable command.

Event(s) generated (unless masked away): When the HCI_LE_Set_Advertising_Set_Random_Address command has completed, an HCI_Command_Complete event shall be generated.

Table 7.2: Advertising_Event_Properties values for legacy PDUs

• If extended advertising PDU types are being used (bit 4 = 0) then: The advertisement shall not be both connectable and scannable. High duty cycle directed connectable advertising (≤ 3.75 ms advertising interval) shall not be used (bit 3 = 0).

If the Advertising_Event_Properties parameter does not describe an event type supported by the Controller, contains an invalid bit combination, or specifies a type that does not support advertising data when the advertising set already contains some, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

The parameters beginning with “Secondary” are only valid when extended advertising PDU types are being used (bit 4 = 0).

The Own_Address_Type parameter shall be ignored for undirected anonymous advertising (bit 2 = 0 and bit 5 = 1).

If Directed advertising is selected, the Peer_Address_Type and Peer_Address shall be valid and the Advertising_Filter_Policy parameter shall be ignored.

The Primary_Advertising_Interval_Min parameter shall be less than or equal to the Primary_Advertising_Interval_Max parameter. The Primary_Advertising_Interval_Min and Primary_Advertising_Interval_Max parameters should not be the same value so that the Controller can choose the best advertising interval given other activities.

For high duty cycle connectable directed advertising event type (ADV_DIRECT_IND), the Primary_Advertising_Interval_Min and Primary_Advertising_Interval_Max parameters are not used and shall be ignored. If the primary advertising interval range provided by the Host (Primary_Advertising_Interval_Min, Primary_Advertising_Interval_Max) is outside the advertising interval range supported by the Controller, then the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

The Primary_Advertising_Channel_Map is a bit field that indicates the advertis- ing channel indices that shall be used when transmitting advertising packets. At least one channel bit shall be set in the Primary_Advertising_Channel_Map parameter.

The Own_Address_Type parameter specifies the type of address being used in the advertising packets. For random addresses, the address is specified by the HCI_LE_Set_Advertising_Set_Random_Address command.

If Own_Address_Type equals 0x02 or 0x03, the Peer_Address parameter contains the peer’s Identity Address and the Peer_Address_Type parameter contains the peer’s Identity Type (i.e., 0x00 or 0x01). These parameters are used to locate the corresponding local IRK in the resolving list; this IRK is used to generate their own address used in the advertisement.

The Advertising_TX_Power parameter indicates the maximum power level at which the advertising packets are to be transmitted on the advertising physical channels. The Controller shall choose a power level lower than or equal to the one specified by the Host.

The Primary_Advertising_PHY parameter indicates the PHY on which the advertising packets are transmitted on the primary advertising physical channel. If legacy advertising PDUs are being used, the Primary_Advertising_PHY shall indicate the LE 1M PHY. The Secondary_Advertising_PHY parameter indicates the PHY on which the advertising packets are be transmitted on the secondary advertising physical channel. If the Host specifies a PHY that is not supported by the Controller, including a value that is reserved for future use, it should return the error code Unsupported Feature or Parameter Value (0x11). If Constant Tone Extensions are enabled for the advertising set and Secondary_Advertising_PHY specifies a PHY that does not allow Constant Tone Extensions, the Controller shall return the error code Command Disallowed (0x0C).

The Secondary_Advertising_Max_Skip parameter is the maximum number of advertising events that can be skipped before the AUX_ADV_IND can be sent.

The Advertising_SID parameter specifies the value to be transmitted in the Advertising SID subfield of the ADI field of the Extended Header of those advertising physical channel PDUs that have an ADI field. If the advertising set only uses PDUs that do not contain an ADI field, Advertising_SID shall be ignored.

The Scan_Request_Notification_Enable parameter indicates whether the Controller shall send notifications upon the receipt of a scan request PDU that is in response to an advertisement from the specified advertising set that contains its device address and is from a scanner that is allowed by the advertising filter policy.

The Controller shall set the Selected_TX_Power return parameter to the transmit power that it will use for transmitting the advertising packets for the specified advertising set. The Controller shall only change this value if requested by the Host. If the radiated power level will vary between packets (e.g., because of frequency-dependent properties of the transmitter) then the value should be the best estimate of the maximum power used.

If the Host issues this command when advertising is enabled for the specified advertising set, the Controller shall return the error code Command Disallowed (0x0C).

If the Host issues this command when periodic advertising is enabled for the specified advertising set and connectable, scannable, legacy, or anonymous advertising is specified, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If periodic advertising is enabled for the advertising set and the Secondary_Advertising_PHY parameter does not specify the PHY currently being used for the periodic advertising, the Controller shall return the error code Command Disallowed (0x0C).

If the Advertising_Handle does not identify an existing advertising set and the Controller is unable to support a new advertising set at present, the Controller shall return the error code Memory Capacity Exceeded (0x07).

If the advertising set already contains advertising data or scan response data, extended advertising is being used, and the length of the data is greater than the maximum that the Controller can transmit within the longest possible auxiliary advertising segment consistent with the parameters, the Controller shall return the error code Packet Too Long (0x45). If advertising on the LE Coded PHY, the S=8 coding shall be assumed.

Event(s) generated (unless masked away): When the HCI_LE_Set_Extended_Advertising_Parameters command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.
p_return – [out] Extra return parameters.

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_ext_adv_data(const sdc_hci_cmd_le_set_ext_adv_data_t *p_params)

LE Set Extended Advertising Data.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.54

The HCI_LE_Set_Extended_Advertising_Data command is used to set the data used in advertising PDUs that have a data field. This command may be issued at any time after an advertising set identified by the Advertising_Handle parameter has been created using the HCI_LE_Set_Extended_Advertising_- Parameters command (see Section 7.8.53), regardless of whether advertising in that set is enabled or disabled.

If advertising is currently enabled for the specified advertising set, the Controller shall use the new data in subsequent extended advertising events for this advertising set. If an extended advertising event is in progress when this command is issued, the Controller may use the old or new data for that event.

If advertising is currently disabled for the specified advertising set, the data shall be kept by the Controller and used once advertising is enabled for that set. The data shall be discarded when the advertising set is removed.

Only the significant part of the advertising data should be transmitted in the advertising packets as defined in [Vol 3] Part C, Section 11.

The Host may set the advertising data in one or more operations using the Operation parameter in the command. If the combined length of the data exceeds the capacity of the advertising set identified by the Advertising_- Handle parameter (see Section 7.8.57 LE Read Maximum Advertising Data Length command) or the amount of memory currently available, all the data shall be discarded and the Controller shall return the error code Memory Capacity Exceeded (0x07).

If the advertising set uses extended advertising and the combined length of the data is greater than the maximum that the Controller can transmit within the longest possible auxiliary advertising segment consistent with the current parameters of the advertising set (using the current advertising interval if advertising is enabled), all the data shall be discarded and the Controller shall return the error code Packet Too Long (0x45). If advertising on the LE Coded PHY, the S=8 coding shall be assumed. If Operation indicates the start of new data (values 0x01 or 0x03), then any existing partial or complete advertising data shall be discarded.

If the advertising data is discarded by the command or the combined length of the data after the command completes is zero, the advertising set will have no advertising data.

If Operation is 0x04, the behavior is the same as if the current advertising data had been sent again; this can be used to cause the Advertising DID value to be updated (see [Vol 6] Part B, Section 4.4.2.11).

The Fragment_Preference parameter provides a hint to the Controller as to whether advertising data should be fragmented.

If the advertising set specifies a type that does not support advertising data, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the advertising set uses legacy advertising PDUs that support advertising data and either Operation is not 0x03 or the Advertising_Data_Length parameter exceeds 31 octets, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If Operation is 0x04 and: • advertising is currently disabled for the advertising set; • the advertising set contains no data; • the advertising set uses legacy PDUs; or • Advertising_Data_Length is not zero;

then the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If Operation is not 0x03 or 0x04 and Advertising_Data_Length is zero, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If advertising is currently enabled for the specified advertising set and Operation does not have the value 0x03 or 0x04, the Controller shall return the error code Command Disallowed (0x0C).

If advertising is currently enabled for the specified advertising set, the advertising set uses extended advertising, and the length of the data is greater than the maximum that the Controller can transmit within the longest possible auxiliary advertising segment consistent with the current parameters of the advertising set, the Controller shall return the error code Packet Too Long (0x45). If advertising on the LE Coded PHY, the S=8 coding shall be assumed.

If the advertising set corresponding to the Advertising_Handle parameter does not exist, then the Controller shall return the error code Unknown Advertising Identifier (0x42).

Event(s) generated (unless masked away): When the HCI_LE_Set_Extended_Advertising_Data command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_ext_scan_response_data(const sdc_hci_cmd_le_set_ext_scan_response_data_t *p_params)

LE Set Extended Scan Response Data.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.55

The HCI_LE_Set_Extended_Scan_Response_Data command is used to provide scan response data used in scanning response PDUs. This command may be issued at any time after the advertising set identified by the Advertis- ing_Handle parameter has been created using the HCI_LE_Set_Extended_- Advertising_Parameters command (see Section 7.8.53) regardless of whether advertising in that set is enabled or disabled.

If advertising is currently enabled for the specified advertising set, the Controller shall use the new data in subsequent extended advertising events for this advertising set. If an extended advertising event is in progress when this command is issued, the Controller may use the old or new data for that event.

If advertising is currently disabled for the specified advertising set, the data shall be kept by the Controller and used once advertising is enabled for that set. The data shall be discarded when the advertising set is removed.

Only the significant part of the scan response data should be transmitted in the advertising packets as defined in [Vol 3] Part C, Section 11.

The Host may set the scan response data in one or more operations using the Operation parameter in the command. If the combined length of the data exceeds the capacity of the advertising set identified by the Advertising_Handle parameter (see Section 7.8.57 LE Read Maximum Advertising Data Length command) or the amount of memory currently available, all the data shall be discarded and the Controller shall return the error code Memory Capacity Exceeded (0x07).

If Operation indicates the start of new data (values 0x01 or 0x03), then any existing partial or complete scan response data shall be discarded.

If the scan response data is discarded by the command or the combined length of the data after the command completes is zero, the advertising set will have no scan response data. The Fragment_Preference parameter provides a hint to the Controller as to whether advertising data should be fragmented.

If the advertising set is non-scannable and the Host uses this command other than to discard existing data, the Controller shall return the error code Invalid HCI Command Parameters (0x12). If the advertising set uses scannable leg- acy advertising PDUs and either Operation is not 0x03 or the Scan_- Response_Data_Length parameter exceeds 31 octets, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If Operation is not 0x03 and Scan_Response_Data_Length is zero, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If advertising is currently enabled for the specified advertising set and Operation does not have the value 0x03, the Controller shall return the error code Command Disallowed (0x0C).

If the advertising set uses extended advertising and the combined length of the data is greater than the maximum that the Controller can transmit within the longest possible auxiliary advertising segment consistent with the current parameters of the advertising set (using the current advertising interval if advertising is enabled), all the data shall be discarded and the Controller shall return the error code Packet Too Long (0x45). If advertising on the LE Coded PHY, the S=8 coding shall be assumed.

If the advertising set uses scannable extended advertising PDUs, advertising is currently enabled for the specified advertising set, and Scan_Response_- Data_Length is zero, the Controller shall return the error code Command Disallowed (0x0C).

If the advertising set corresponding to the Advertising_Handle parameter does not exist, then the Controller shall return the error code Unknown Advertising Identifier (0x42).

Event(s) generated (unless masked away): When the HCI_LE_Set_Extended_Scan_Response_Data command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_ext_adv_enable(const sdc_hci_cmd_le_set_ext_adv_enable_t *p_params)

LE Set Extended Advertising Enable.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.56

The HCI_LE_Set_Extended_Advertising_Enable command is used to request the Controller to enable or disable one or more advertising sets using the advertising sets identified by the Advertising_Handle[i] parameter. The Control- ler manages the timing of advertisements in accordance with the advertising parameters given in the HCI_LE_Set_Extended_Advertising_Parameters command. The Num_Sets parameter is the number of advertising sets contained in the parameter arrays. If Enable and Num_Sets are both set to 0x00, then all advertising sets are disabled.

The Controller shall only start an advertising event when the corresponding advertising set is enabled. The Controller shall continue advertising until all advertising sets have been disabled. An advertising set shall be disabled when the Host issues an HCI_LE_Set_Extended_Advertising_Enable command with the Enable parameter set to 0x00 (Advertising is disabled), a connection is cre- ated using that advertising set, the duration specified in the Duration[i] parame- ter expires, or the number of extended advertising events transmitted for the set exceeds the Max_Extended_Advertising_Events[i] parameter.

The Duration[i] parameter indicates the duration for which that advertising set is enabled. The duration begins at the start of the first advertising event of this advertising set. The Controller should not start an extended advertising event that it cannot complete within the duration.

If the advertising is high duty cycle connectable directed advertising, then Duration[i] shall be less than or equal to 1.28 seconds and shall not be equal to 0.

The Max_Extended_Advertising_Events[i] parameter, if non-zero, indicates the maximum number of extended advertising events that shall be sent prior to disabling the extended advertising set even if the Duration[i] parameter has not expired.

Duration[i] and Max_Extended_Advertising_Events[i] shall be ignored when Enable is set to 0x00.

If the HCI_LE_Set_Extended_Advertising_Enable command is sent again for an advertising set while that set is enabled, the timer used for the duration and the number of events counter are reset and any change to the random address shall take effect.

Disabling the advertising set identified by the Advertising_Handle[i] parameter does not disable any periodic advertising associated with that set.

Disabling an advertising set that is already disabled has no effect.

If the same advertising set is identified by more than one entry in the Advertising_Handle[i] arrayed parameter, then the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the advertising set corresponding to the Advertising_Handle[i] parameter does not exist, then the Controller shall return the error code Unknown Advertising Identifier (0x42).

The remainder of this section only applies if Enable is set to 0x01.

If Num_Sets is set to 0x00, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the advertising set contains partial advertising data or partial scan response data, the Controller shall return the error code Command Disallowed (0x0C).

If the advertising set uses scannable extended advertising PDUs and no scan response data is currently provided, the Controller shall return the error code Command Disallowed (0x0C).

If the advertising set uses connectable extended advertising PDUs and the advertising data in the advertising set will not fit in the AUX_ADV_IND PDU, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

Note: The maximum amount of data that will fit in the PDU depends on which options are selected and on the maximum length of PDU that the Controller is able to transmit.

If extended advertising is being used and the length of any advertising data or of any scan response data is greater than the maximum that the Controller can transmit within the longest possible auxiliary advertising segment consistent with the chosen advertising interval, the Controller shall return the error code Packet Too Long (0x45). If advertising on the LE Coded PHY, the S=8 coding shall be assumed.

If the advertising set’s Own_Address_Type parameter is set to 0x00 and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12).

If the advertising set’s Own_Address_Type parameter is set to 0x01 and the random address for the advertising set has not been initialized using the HCI_LE_Set_Advertising_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the advertising set’s Own_Address_Type parameter is set to 0x02, the Controller’s resolving list did not contain a matching entry, and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12).

If the advertising set’s Own_Address_Type parameter is set to 0x03, the controller’s resolving list did not contain a matching entry, and the random address for the advertising set has not been initialized using the HCI_LE_Set_Advertising_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

Event(s) generated (unless masked away): When the HCI_LE_Set_Extended_Advertising_Enable command has completed, an HCI_Command_Complete event shall be generated.

If the Duration[i] parameter is set to a value other than 0x0000, an HCI_LE_- Advertising_Set_Terminated event shall be generated when the duration spec- ified in the Duration[i] parameter expires. However, if the advertising set is for high duty cycle connectable directed advertising and no connection is created before the duration expires, an HCI_LE_Connection_Complete or HCI_LE_- Enhanced_Connection_Complete event with the Status parameter set to the error code Advertising Timeout (0x3C) may be generated instead of or in addi- tion to the HCI_LE_Advertising_Set_Terminated event. If the Controller gener- ates both events, they may be in either order.

If the Max_Extended_Advertising_Events[i] parameter is set to a value other than 0x00, an HCI_LE_Advertising_Set_Terminated event shall be generated when the maximum number of extended advertising events has been transmitted by the Controller.

If the advertising set is connectable and a connection gets created, an HCI_LE_Connection_Complete or HCI_LE_Enhanced_Connection_Complete event shall be generated followed by an HCI_LE_Advertising_Set_Terminated event with the Status parameter set to 0x00. The Controller should not send any other events in between these two events.

Note: If this command is used to disable advertising at about the same time that a connection is established or the advertising duration expires, there is a possible race condition in that it is possible to receive both an HCI_LE_- Connection_Complete, HCI_LE_Enhanced_Connection_Complete, or HCI_LE_Advertising_Set_Terminated event and the HCI_Command_- Complete event for this command.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

LE Read Maximum Advertising Data Length.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.57

The HCI_LE_Read_Maximum_Advertising_Data_Length command is used to read the maximum length of data supported by the Controller for use as advertisement data or scan response data in an advertising event or as periodic advertisement data.

Note: The maximum amount may be fragmented across multiple PDUs (see [Vol 6] Part B, Section 2.3.4.9).

LE Read Number of Supported Advertising Sets.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.58

The HCI_LE_Read_Number_of_Supported_Advertising_Sets command is used to read the maximum number of advertising sets supported by the advertising Controller at the same time.

Note: The number of advertising sets that can be supported is not fixed and the Controller can change it at any time because the memory used to store advertising sets can also be used for other purposes.

Event(s) generated (unless masked away): When the HCI_LE_Read_Number_of_Supported_Advertising_Sets command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_return – [out] Extra return parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

LE Remove Advertising Set.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.59

The HCI_LE_Remove_Advertising_Set command is used to remove an advertising set from the Controller.

If the advertising set corresponding to the Advertising_Handle parameter does not exist, then the Controller shall return the error code Unknown Advertising Identifier (0x42). If advertising or periodic advertising on the advertising set is enabled, then the Controller shall return the error code Command Disallowed (0x0C).

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.60

The HCI_LE_Clear_Advertising_Sets command is used to remove all existing advertising sets from the Controller.

If advertising or periodic advertising is enabled on any advertising set, then the Controller shall return the error code Command Disallowed (0x0C).

Note: All advertising sets are cleared on HCI reset.

Event(s) generated (unless masked away): When the HCI_LE_Clear_Advertising_Sets command has completed, an HCI_Command_Complete event shall be generated.

Return values: 0 – if success.
Returns: Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_periodic_adv_params(const sdc_hci_cmd_le_set_periodic_adv_params_t *p_params)

LE Set Periodic Advertising Parameters.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.61

The HCI_LE_Set_Periodic_Advertising_Parameters command is used by the Host to set the parameters for periodic advertising.

The Advertising_Handle parameter identifies the advertising set whose periodic advertising parameters are being configured. If the corresponding advertising set does not already exist, then the Controller shall return the error code Unknown Advertising Identifier (0x42).

The Periodic_Advertising_Interval_Min parameter shall be less than or equal to the Periodic_Advertising_Interval_Max parameter. The Periodic_Advertising_- Interval_Min and Periodic_Advertising_Interval_Max parameters should not be the same value to enable the Controller to determine the best advertising interval given other activities.

The Periodic_Advertising_Properties parameter indicates which fields should be included in the advertising packet.

If the advertising set identified by the Advertising_Handle specified scannable, connectable, legacy, or anonymous advertising, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the Host issues this command when periodic advertising is enabled for the specified advertising set, the Controller shall return the error code Command Disallowed (0x0C).

If the Advertising_Handle does not identify an advertising set that is already configured for periodic advertising and the Controller is unable to support more periodic advertising at present, the Controller shall return the error code Memory Capacity Exceeded (0x07).

If the advertising set already contains periodic advertising data and the length of the data is greater than the maximum that the Controller can transmit within a periodic advertising interval of Periodic_Advertising_Interval_Max, the Controller shall return the error code Packet Too Long (0x45). If advertising on the LE Coded PHY, the S=8 coding shall be assumed.

Event(s) generated (unless masked away): When the HCI_LE_Set_Periodic_Advertising_Parameters command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_periodic_adv_data(const sdc_hci_cmd_le_set_periodic_adv_data_t *p_params)

LE Set Periodic Advertising Data.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.62

The HCI_LE_Set_Periodic_Advertising_Data command is used to set the data used in periodic advertising PDUs. This command may be issued at any time after the advertising set identified by the Advertising_Handle parameter has been configured for periodic advertising using the HCI_LE_Set_Periodic_- Advertising_Parameters command (see Section 7.8.61), regardless of whether periodic advertising in that set is enabled or disabled. If the advertising set has not been configured for periodic advertising, then the Controller shall return the error code Command Disallowed (0x0C).

If periodic advertising is currently enabled for the specified advertising set, the Controller shall use the new data in subsequent periodic advertising events for this advertising set. If a periodic advertising event is in progress when this command is issued, the Controller may use the old or new data for that event.

If periodic advertising is currently disabled for the specified advertising set, the data shall be kept by the Controller and used once periodic advertising is enabled for that set. The data shall be discarded when the advertising set is removed.

Only the significant part of the periodic advertising data should be transmitted in the advertising packets as defined in [Vol 3] Part C, Section 11.

The Host may set the periodic advertising data in one or more operations using the Operation parameter in the command. If the combined length of the data exceeds the capacity of the advertising set identified by the Advertising_- Handle parameter (see Section 7.8.57 LE Read Maximum Advertising Data Length command) or the amount of memory currently available, all the data shall be discarded and the Controller shall return the error code Memory Capacity Exceeded (0x07).

If the combined length of the data is greater than the maximum that the Con- troller can transmit within the current periodic advertising interval (if periodic advertising is currently enabled) or the Periodic_Advertising_Interval_Max for the advertising set (if currently disabled), all the data shall be discarded and the Controller shall return the error code Packet Too Long (0x45). If advertising on the LE Coded PHY, the S=8 coding shall be assumed. If Operation indicates the start of new data (values 0x01 or 0x03), then any existing partial or complete data shall be discarded.

If Operation is 0x04, then the behavior is the same as if the current periodic advertising data had been sent again; this can be used to cause the Advertising DID value to be updated (see [Vol 6] Part B, Section 4.4.2.11).

If Operation is 0x04 and: • periodic advertising is currently disabled for the advertising set; • the periodic advertising set contains no data; or • Advertising_Data_Length is not zero;

then the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If Operation is not 0x03 or 0x04 and Advertising_Data_Length is zero, then the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the periodic advertising data is discarded by the command or the combined length of the data after the command completes is zero, the advertising set will have no periodic advertising data.

If periodic advertising is currently enabled for the specified advertising set and Operation does not have the value 0x03 or 0x04, then the Controller shall return the error code Command Disallowed (0x0C).

If the advertising set corresponding to the Advertising_Handle parameter does not exist, then the Controller shall return the error code Unknown Advertising Identifier (0x42).

Event(s) generated (unless masked away): When the HCI_LE_Set_Periodic_Advertising_Data command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_periodic_adv_enable(const sdc_hci_cmd_le_set_periodic_adv_enable_t *p_params)

LE Set Periodic Advertising Enable.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.63

The HCI_LE_Set_Periodic_Advertising_Enable command is used to request the Controller to enable or disable the periodic advertising for the advertising set specified by the Advertising_Handle parameter (ordinary advertising is not affected).

If the advertising set is not currently enabled (see the HCI_LE_Set_Extended_- Advertising_Enable command), the periodic advertising is not started until the advertising set is enabled. Once the advertising set has been enabled, the Controller shall continue periodic advertising until the Host issues an HCI_LE_- Set_Periodic_Advertising_Enable command with bit 0 of Enable set to 0 (peri- odic advertising is disabled). Disabling the advertising set has no effect on the periodic advertising once the advertising set has been enabled.

The Controller manages the timing of advertisements in accordance with the advertising parameters given in the HCI_LE_Set_Periodic_Advertising_- Parameters command.

If the advertising set corresponding to the Advertising_Handle parameter does not exist, the Controller shall return the error code Unknown Advertising Identifier (0x42).

If bit 0 of Enable is set to 1 (periodic advertising is enabled) and the advertising set contains partial periodic advertising data, the Controller shall return the error code Command Disallowed (0x0C).

If bit 0 of Enable is set to 1 and the Host has not issued the HCI_LE_Set_- Periodic_Advertising_Parameters command for the advertising set, the Con- troller shall either use vendor-specified parameters or return the error code Command Disallowed (0x0C).

If bit 0 of Enable is set to 1 and the length of the periodic advertising data is greater than the maximum that the Controller can transmit within the chosen periodic advertising interval, the Controller shall return the error code Packet Too Long (0x45). If advertising on the LE Coded PHY, the S=8 coding shall be assumed.

If bit 0 of Enable is set to 1 and the advertising set identified by the Advertising_Handle specified scannable, connectable, legacy, or anonymous advertising, the Controller shall return the error code Command Disallowed (0x0C).

If bit 0 of Enable is set to 0 and the Controller supports the Periodic Advertising ADI Support feature, then the Controller shall ignore bit 1.

If bit 1 of Enable is set to 1 and the Controller does not support the Periodic Advertising ADI Support feature, the Controller shall return an error which should use the error code Unsupported Feature or Parameter Value (0x11).

Enabling periodic advertising when it is already enabled can cause the random address to change. Disabling periodic advertising when it is already disabled has no effect.

Event(s) generated (unless masked away): When the HCI_LE_Set_Periodic_Advertising_Enable command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_ext_scan_params(const sdc_hci_cmd_le_set_ext_scan_params_t *p_params)

LE Set Extended Scan Parameters.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.64

The HCI_LE_Set_Extended_Scan_Parameters command is used to set the extended scan parameters to be used on the advertising physical channels.

The Scanning_PHYs parameter indicates the PHY(s) on which the advertising packets should be received on the primary advertising physical channel. The Host may enable one or more scanning PHYs. If the Host specifies a PHY that is not supported by the Controller, including a bit that is reserved for future use, it should return the error code Unsupported Feature or Parameter Value (0x11). The Scan_Type[i], Scan_Interval[i], and Scan_Window[i] parameters array elements are ordered in the same order as the set bits in the Scanning_PHY parameter, starting from bit 0. The number of array elements is determined by the number of bits set in the Scanning_PHY parameter.

The Scan_Type[i] parameter specifies the type of scan to perform.

The Scan_Interval[i] and Scan_Window[i] parameters are recommendations from the Host on how long (Scan_Window[i]) and how frequently (Scan_Interval[i]) the Controller should scan (see [Vol 6] Part B, Section 4.4.3); however the frequency and length of the scan is implementation specific. If the requested scan cannot be supported by the implementation, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

The Own_Address_Type parameter indicates the type of address being used in the scan request packets.

If the Host issues this command when scanning is enabled in the Controller, the Controller shall return the error code Command Disallowed (0x0C).

Event(s) generated (unless masked away): When the HCI_LE_Set_Extended_Scan_Parameters command has completed, an HCI_Command_Complete event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_ext_scan_enable(const sdc_hci_cmd_le_set_ext_scan_enable_t *p_params)

LE Set Extended Scan Enable.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.65

The HCI_LE_Set_Extended_Scan_Enable command is used to enable or disable scanning for both legacy and extended advertising PDUs.

The Enable parameter determines whether scanning is enabled or disabled. If it is set to 0x00, the remaining parameters shall be ignored.

If Enable is set to 0x01 and the Host has not issued the HCI_LE_Set_- Extended_Scan_Parameters command, the Controller shall either use vendor- specified parameters or return the error code Command Disallowed (0x0C).

The Filter_Duplicates parameter controls whether the Link Layer should filter out duplicate advertising reports (filtering duplicates enabled) to the Host or if the Link Layer should generate advertising reports for each packet received (filtering duplicates disabled). See [Vol 6] Part B, Section 4.4.3.5.

If the Filter_Duplicates parameter is set to 0x00, all advertisements received from advertisers shall be sent to the Host in advertising report events.

If the Filter_Duplicates parameter is set to 0x01, duplicate advertisements should not be sent to the Host in advertising report events until scanning is disabled.

If the Filter_Duplicates parameter is set to 0x02, duplicate advertisements in a single scan period should not be sent to the Host in advertising report events; this setting shall only be used if both Period and Duration are non-zero. If Filter_Duplicates is set to 0x02 and either Period or Duration to zero, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the Duration parameter is zero or both the Duration parameter and Period parameter are non-zero, the Controller shall continue scanning until scanning is disabled by the Host issuing an HCI_LE_Set_Extended_Scan_Enable command with the Enable parameter set to 0x00 (Scanning is disabled). The Period parameter shall be ignored when the Duration parameter is zero.

If the Duration parameter is non-zero and the Period parameter is zero, the Controller shall continue scanning until the duration specified in the Duration parameter has expired. If both the Duration and Period parameters are non-zero and the Duration is greater than or equal to the Period, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

When the Duration and Period parameters are non-zero, the Controller shall scan for the duration of the Duration parameter within a scan period specified by the Period parameter. After the scan period has expired, a new scan period shall begin and scanning shall begin again for the duration specified. The scan periods continue until the Host disables scanning.

If the HCI_LE_Set_Extended_Scan_Enable command with Enable set to 0x01 is sent while scanning is already enabled, the timers used for duration and period are reset to the new parameter values and a new scan period is started. Any change to the Filter_Duplicates setting or the random address shall take effect.

Disabling scanning when it is disabled has no effect.

Note: The duration of a scan period refers to the time spent scanning on both the primary and secondary advertising physical channels. However, expiry of the duration does not prevent the Link Layer from scanning for and receiving auxiliary packets of received advertisements.

If Enable is set to 0x01, the scanning parameters’ Own_Address_Type parameter is set to 0x00 or 0x02, and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12).

If Enable is set to 0x01, the scanning parameters’ Own_Address_Type parameter is set to 0x01 or 0x03, and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

Event(s) generated (unless masked away): When the HCI_LE_Set_Extended_Scan_Enable command has completed, an HCI_Command_Complete event shall be generated.

Zero or more LE Extended Advertising Reports are generated by the Controller based on any advertising packets received and the duplicate filtering in effect. More than one advertising packet may be reported in each HCI_LE_- Extended_Advertising_Report event.

At the end of a single scan (Duration non-zero but Period zero), an HCI_LE_- Scan_Timeout event shall be generated.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_ext_create_conn(const sdc_hci_cmd_le_ext_create_conn_t *p_params)

LE Extended Create Connection.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.66

The HCI_LE_Extended_Create_Connection command is used to create an ACL connection, with the local device in the Central role, to a connectable advertiser.

If a connection is created with the local device in the Peripheral role while this command is pending, then this command remains pending.

The Initiator_Filter_Policy parameter is used to determine whether the Filter Accept List is used. If the Filter Accept List is not used, the Peer_Address_Type and the Peer_Address parameters specify the address type and address of the advertising device to connect to.

The Own_Address_Type parameter indicates the type of address being used in the connection request packets.

The Peer_Address_Type parameter indicates the type of address used in the connectable advertisement sent by the peer.

The Peer_Address parameter indicates the Peer’s Public Device Address, Random (static) Device Address, Non-Resolvable Private Address, or Resolvable Private Address depending on the Peer_Address_Type parameter.

The Initiating_PHYs parameter indicates the PHY(s) on which the advertising packets should be received on the primary advertising physical channel and the PHYs for which connection parameters have been specified. The Host may enable one or more initiating PHYs. If the Host specifies a PHY that is not supported by the Controller, including a bit that is reserved for future use, the latter should return the error code Unsupported Feature or Parameter Value (0x11). The array elements of the arrayed parameters are ordered in the same order as the set bits in the Initiating_PHYs parameter, starting from bit 0. The number of array elements is determined by the number of bits set in the Initiating_PHYs parameter. When a connectable advertisement is received and a connection request is sent on one PHY, scanning on any other PHYs is terminated.

The Scan_Interval[i] and Scan_Window[i] parameters are recommendations from the Host on how long (Scan_Window[i]) and how frequently (Scan_Interval[i]) the Controller should scan (see [Vol 6] Part B, Section 4.5.3); however the frequency and length of the scan is implementation specific. If the requested scan cannot be supported by the implementation, the Controller shall return the error code Invalid HCI Command Parameters (0x12). If bit 1 is set in Initiating_PHYs, the values for the LE 2M PHY shall be ignored.

The Connection_Interval_Min[i] and Connection_Interval_Max[i] parameters define the minimum and maximum allowed connection interval. The Connection_Interval_Min[i] parameter shall not be greater than the Connection_Interval_Max[i] parameter.

The Max_Latency[i] parameter defines the maximum allowed Peripheral latency (see [Vol 6] Part B, Section 4.5.1).

The Supervision_Timeout[i] parameter defines the link supervision timeout for the connection. The Supervision_Timeout[i] in milliseconds shall be larger than (1 + Max_Latency[i]) * Connection_Interval_Max[i] * 2, where Connection_- Interval_Max[i] is given in milliseconds (see [Vol 6] Part B, Section 4.5.2).

The Min_CE_Length[i] and Max_CE_Length[i] parameters provide the Controller with the expected minimum and maximum length of the connection events. The Min_CE_Length[i] parameter shall be less than or equal to the Max_CE_Length[i] parameter. The Controller is not required to use these values.

Where the connection is made on a PHY whose bit is not set in the Initiating_- PHYs parameter, the Controller shall use the Connection_Interval_Min[i], Connection_Interval_Max[i], Max_Latency[i], Supervision_Timeout[i], Min_CE_Length[i], and Max_CE_Length[i] parameters for an implementation- chosen PHY whose bit is set in the Initiating_PHYs parameter.

If the Host issues this command when another HCI_LE_Extended_Create_- Connection command is pending in the Controller, the Controller shall return the error code Command Disallowed (0x0C).

If the Own_Address_Type parameter is set to 0x00 and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12). If the Own_Address_Type parameter is set to 0x01 and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the Own_Address_Type parameter is set to 0x02, the Initiator_Filter_Policy parameter is set to 0x00, the Controller’s resolving list did not contain a matching entry, and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12).

If the Own_Address_Type parameter is set to 0x02, the Initiator_Filter_Policy parameter is set to 0x01, and the device does not have a public address, the Controller should return an error code which should be Invalid HCI Command Parameters (0x12).

If the Own_Address_Type parameter is set to 0x03, the Initiator_Filter_Policy parameter is set to 0x00, the controller’s resolving list did not contain a matching entry, and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the Own_Address_Type parameter is set to 0x03, the Initiator_Filter_Policy parameter is set to 0x01, and the random address for the device has not been initialized using the HCI_LE_Set_Random_Address command, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the Initiating_PHYs parameter does not have at least one bit set for a PHY allowed for scanning on the primary advertising physical channel, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

Event(s) generated (unless masked away): When the Controller receives the HCI_LE_Extended_Create_Connection com- mand, the Controller sends the HCI_Command_Status event to the Host. An HCI_LE_Enhanced_Connection_Complete event shall be generated when a connection is created because of this command or the connection creation pro- cedure is cancelled; until the event is generated, the command is considered pending. If a connection is created, this event shall be immediately followed by an HCI_LE_Channel_Selection_Algorithm event.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_periodic_adv_create_sync(const sdc_hci_cmd_le_periodic_adv_create_sync_t *p_params)

LE Periodic Advertising Create Sync.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.67

The HCI_LE_Periodic_Advertising_Create_Sync command is used to synchronize with a periodic advertising train from an advertiser and begin receiving periodic advertising packets.

This command may be issued whether or not scanning is enabled and scanning may be enabled and disabled (see the LE Set Extended Scan Enable command) while this command is pending. However, synchronization can only occur when scanning is enabled. While scanning is disabled, no attempt to synchronize will take place.

The Options parameter is used to determine whether the Periodic Advertiser List is used, whether HCI_LE_Periodic_Advertising_Report events for this periodic advertising train are initially enabled or disabled, and whether duplicate reports are filtered or not. If the Periodic Advertiser List is not used, the Advertising_SID, Advertiser Address_Type, and Advertiser Address parameters specify the periodic advertising device to listen to; otherwise they shall be ignored.

The Advertising_SID parameter, if used, specifies the value that must match the Advertising SID subfield in the ADI field of the received advertisement for it to be used to synchronize.

The Skip parameter specifies the maximum number of consecutive periodic advertising events that the receiver may skip after successfully receiving a periodic advertising packet.

The Sync_Timeout parameter specifies the maximum permitted time between successful receives. If this time is exceeded, synchronization is lost.

The Sync_CTE_Type parameter specifies whether to only synchronize to periodic advertising with certain types of Constant Tone Extension (a value of 0 indicates that the presence or absence of a Constant Tone Extension is irrelevant). If the periodic advertising has the wrong type of Constant Tone Extension then: • If bit 0 of Options is set, the Controller shall ignore this address and SID and continue to search for other periodic advertisements. • Otherwise, the Controller shall cancel the synchronization with the error code Unsupported Remote Feature (0x1A).

If the periodic advertiser changes the type of Constant Tone Extension after the scanner has synchronized with the periodic advertising, the scanner’s Link Layer shall remain synchronized.

If the Host sets all the non-reserved bits of the Sync_CTE_Type parameter to 1, the Controller shall return the error code Command Disallowed (0x0C).

Irrespective of the value of the Skip parameter, the Controller should stop skipping packets before the Sync_Timeout would be exceeded.

If the Host issues this command when another HCI_LE_Periodic_Advertising_- Create_Sync command is pending, the Controller shall return the error code Command Disallowed (0x0C).

If the Host issues this command with bit 0 of Options not set and with Advertising_SID, Advertiser_Address_Type, and Advertiser_Address the same as those of a periodic advertising train that the Controller is already synchronized to, the Controller shall return the error code Connection Already Exists (0x0B).

If the Host issues this command and the Controller has insufficient resources to handle any more periodic advertising trains, the Controller shall return the error code Memory Capacity Exceeded (0x07).

If bit 1 of Options is set to 1 and the Controller supports the Periodic Advertising ADI Support feature, then the Controller shall ignore bit 2.

If bit 1 of Options is set to 0, bit 2 is set to 1, and the Controller does not support the Periodic Advertising ADI Support feature, then the Controller shall return an error which should use the error code Unsupported Feature or Parameter Value (0x11).

If bit 1 of the Options parameter is set to 1 and the Controller does not support the HCI_LE_Set_Periodic_Advertising_Receive_Enable command, the Controller shall return the error code Connection Failed to be Established / Synchronization Timeout (0x3E).

Event(s) generated (unless masked away): When the HCI_LE_Periodic_Advertising_Create_Sync command has been received, the Controller sends the HCI_Command_Status event to the Host. An HCI_LE_Periodic_Advertising_Sync_Established event shall be generated when the Controller starts receiving periodic advertising packets.

When the Controller receives periodic advertising packets then, if reporting is enabled, it sends HCI_LE_Periodic_Advertising_Report events to the Host.

Note: The HCI_LE_Periodic_Advertising_Sync_Established event can be sent as a result of synchronization being canceled by an HCI_LE_Periodic_- Advertising_Create_Sync_Cancel command.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

The HCI_LE_Periodic_Advertising_Create_Sync_Cancel command is used to cancel the HCI_LE_Periodic_Advertising_Create_Sync command while it is pending.

If the Host issues this command while no HCI_LE_Periodic_Advertising_- Create_Sync command is pending, the Controller shall return the error code Command Disallowed (0x0C).

Event(s) generated (unless masked away): When the HCI_LE_Periodic_Advertising_Create_Sync_Cancel command has completed, the Controller sends an HCI_Command_Complete event to the Host.

After the HCI_Command_Complete is sent and if the cancellation was successful, the Controller sends an HCI_LE_Periodic_Advertising_Sync_- Established event to the Host with the error code Operation Cancelled by Host (0x44).

Return values: 0 – if success.
Returns: Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.70

The HCI_LE_Add_Device_To_Periodic_Advertiser_List command is used to add an entry, consisting of a single device address and SID, to the Periodic Advertiser list stored in the Controller. Any additions to the Periodic Advertiser list take effect immediately. If the entry is already on the list, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the Host issues this command when an HCI_LE_Periodic_Advertising_- Create_Sync command is pending, the Controller shall return the error code Command Disallowed (0x0C).

When a Controller cannot add an entry to the Periodic Advertiser list because the list is full, the Controller shall return the error code Memory Capacity Exceeded (0x07).

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.71

The HCI_LE_Remove_Device_From_Periodic_Advertiser_List command is used to remove one entry from the list of Periodic Advertisers stored in the Controller. Removals from the Periodic Advertisers List take effect immediately.

If the Host issues this command when an HCI_LE_Periodic_Advertising_- Create_Sync command is pending, the Controller shall return the error code Command Disallowed (0x0C).

When a Controller cannot remove an entry from the Periodic Advertiser list because it is not found, the Controller shall return the error code Unknown Advertising Identifier (0x42).

uint8_t sdc_hci_cmd_le_write_rf_path_compensation(const sdc_hci_cmd_le_write_rf_path_compensation_t *p_params)

LE Write RF Path Compensation.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.76

The HCI_LE_Write_RF_Path_Compensation command is used to indicate the RF path gain or loss between the RF transceiver and the antenna contributed by intermediate components. A positive value means a net RF path gain and a negative value means a net RF path loss. The RF_TX_Path_Compensation_- Value parameter shall be used by the Controller to calculate the radiative Tx power level used in HCI commands, HCI events, Advertising physical channel PDUs, and Link Layer Control PDUs using the following equation:

Radiative Tx power level = Tx power level at RF transceiver output + RF_TX_- Path_Compensation_Value

For example, if the Tx power level is +4 (dBm) at RF transceiver output and the RF_TX_Path_Compensation_Value is -1.5 (dB), the radiative Tx power level is +4+(-1.5) = 2.5 (dBm).

The RF_RX_Path_Compensation_Value parameter shall be used by the Controller to calculate the RSSI value reported to the Host.

The default values for the RF path compensation are vendor-specific.

This command can be issued at any time. If this command is issued during an ongoing over-the-air RF activity, the Controller may apply the Tx path compensation immediately or after a vendor-specific delay.

The Controller shall apply a change to the Tx path compensation value either by leaving the power at the transceiver output unchanged and altering the radiative Tx power level or by altering the power at the transceiver output to maintain any previously chosen radiative Tx power level.

If the Host needs to maintain a specific radiative transmit power level for an advertising set, it should disable that set before issuing this command then, after the command completes, reissue the HCI_LE_Set_Extended_- Advertising_Parameters command for that set and then re-enable it.

Event(s) generated (unless masked away): When the HCI_LE_Write_RF_Path_Compensation command has completed, an HCI_Command_Complete event shall be generated.

If the command leads to a change in the local radiative transmit power level for an LE ACL connection, then the Controller shall generate an HCI_LE_- Transmit_Power_Reporting event if local reporting is enabled and initiate a Link Layer Power Change Indication procedure if remote reporting is enabled.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_privacy_mode(const sdc_hci_cmd_le_set_privacy_mode_t *p_params)

LE Set Privacy Mode.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.77

The HCI_LE_Set_Privacy_Mode command is used to allow the Host to specify the privacy mode to be used for a given entry on the resolving list. The effect of this setting is specified in [Vol 6] Part B, Section 4.7.

When an entry on the resolving list is removed, the mode associated with that entry shall also be removed.

LE Set Connectionless CTE Transmit Parameters.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.80

The HCI_LE_Set_Connectionless_CTE_Transmit_Parameters command is used to set the type, length, and antenna switching pattern for the transmission of Constant Tone Extensions in any periodic advertising on the advertising set identified by the Advertising_Handle parameter.

The CTE_Count parameter specifies how many packets with a Constant Tone Extension are to be transmitted in each periodic advertising event. If the number of packets that would otherwise be transmitted is less than this, the Controller shall transmit sufficient AUX_CHAIN_IND PDUs with no AdvData to make up the number. However, if a change in circumstances since this command was issued means that the Controller can no longer schedule all of these packets, it should transmit as many as possible.

If the Host issues this command when Constant Tone Extensions have been enabled in the advertising set, the Controller shall return the error code Command Disallowed (0x0C).

The Switching_Pattern_Length and Antenna_IDs[i] parameters are only used when transmitting an AoD Constant Tone Extension and shall be ignored if CTE_Type specifies an AoA Constant Tone Extension.

If the CTE_Length parameter is greater than the maximum length of Constant Tone Extension supported, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

If the Host requests a type of Constant Tone Extension that the Controller does not support, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

If the Controller is unable to schedule CTE_Count packets in each event, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11). If the advertising set corresponding to the Advertising_Handle parameter does not exist, the Controller shall return the error code Unknown Advertising Identifier (0x42).

If Switching_Pattern_Length is greater than the maximum length of switching pattern supported by the Controller (see Section 7.8.87), the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

If the Controller determines that any of the Antenna_IDs[i] values do not identify an antenna in the device’s antenna array, it shall return the error code Unsupported Feature or Parameter Value (0x11).

Note: Some Controllers may be unable to determine which values do or do not identify an antenna.

Event(s) generated (unless masked away): When the HCI_LE_Set_Connectionless_CTE_Transmit_Parameters command has completed, an HCI_Command_Complete event shall be generated.

LE Set Connectionless CTE Transmit Enable.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.81

The HCI_LE_Set_Connectionless_CTE_Transmit_Enable command is used to request that the Controller enables or disables the use of Constant Tone Extensions in any periodic advertising on the advertising set identified by Advertising_Handle.

In order to start sending periodic advertisements containing a Constant Tone Extension, the Host must also enable periodic advertising using the HCI_LE_Set_Periodic_Advertising_Enable command (see Section 7.8.63).

Note: Periodic advertising can only be enabled when advertising is enabled on the same advertising set, but can continue after advertising has been disabled.

If the Host issues this command before it has issued the HCI_LE_Set_Periodic_Advertising_Parameters command (see Section 7.8.61) for the advertising set, the Controller shall return the error code Command Disallowed (0x0C).

Once enabled, the Controller shall continue advertising with Constant Tone Extensions until either one of the following occurs: • The Host issues an HCI_LE_Set_Connectionless_CTE_Transmit_Enable command with CTE_Enable set to 0x00 (disabling Constant Tone Extensions but allowing periodic advertising to continue). • The Host issues an HCI_LE_Set_Periodic_Advertising_Enable command (see Section 7.8.63) with Enable set to 0x00 (disabling periodic advertising). If periodic advertising is re-enabled then it shall continue to contain Constant Tone Extensions.

If the Host issues this command before it has issued the HCI_LE_Set_Connectionless_CTE_Transmit_Parameters command for the advertising set, the Controller shall return the error code Command Disallowed (0x0C).

If the periodic advertising is on a PHY that does not allow Constant Tone Extensions, the Controller shall return the error code Command Disallowed (0x0C). If the advertising set corresponding to the Advertising_Handle parameter does not exist, the Controller shall return the error code Unknown Advertising Identifier (0x42).

The Host may issue this command when advertising or periodic advertising is enabled in the advertising set.

Event(s) generated (unless masked away): When the HCI_LE_Set_Connectionless_CTE_Transmit_Enable command has completed, an HCI_Command_Complete event shall be generated.

The HCI_LE_Set_Connection_CTE_Transmit_Parameters command is used to set the antenna switching pattern and permitted Constant Tone Extension types used for transmitting Constant Tone Extensions requested by the peer device on the connection identified by the Connection_Handle parameter.

If the Host issues this command when Constant Tone Extension responses have been enabled on the connection, the Controller shall return the error code Command Disallowed (0x0C).

If the CTE_Types parameter has a bit set for a type of Constant Tone Extension that the Controller does not support, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

The Switching_Pattern_Length and Antenna_IDs[i] parameters are only used when transmitting an AoD Constant Tone Extension and shall be ignored when CTE_Types does not have a bit set for an AoD Constant Tone Extension; they do not affect the transmission of an AoA Constant Tone Extension.

If Switching_Pattern_Length is greater than the maximum length of switching pattern supported by the Controller, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

If the Controller determines that any of the Antenna_IDs[i] values do not identify an antenna in the device’s antenna array, it shall return the error code Unsupported Feature or Parameter Value (0x11).

LE Set Periodic Advertising Sync Transfer Parameters.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.91

The HCI_LE_Set_Periodic_Advertising_Sync_Transfer_Parameters command is used to specify how the Controller will process periodic advertising synchronization information received from the device identified by the Connection_Handle parameter (the “transfer mode”).

The Mode parameter specifies the action to be taken when periodic advertising synchronization information is received. If Mode is 0x00, the Controller will ignore the information. Otherwise it will notify the Host and synchronize to the periodic advertising. Mode also specifies whether periodic advertising reports are initially enabled or disabled and whether duplicates are filtered.

The Skip parameter specifies the number of consecutive periodic advertising packets that the receiver may skip after successfully receiving a periodic advertising packet.

The Sync_Timeout parameter specifies the maximum permitted time between successful receives. If this time is exceeded, synchronization is lost.

Irrespective of the value of the Skip parameter, the Controller should stop skipping packets before the Sync_Timeout would be exceeded.

The CTE_Type parameter specifies whether to only synchronize to periodic advertising with certain types of Constant Tone Extension. If the periodic advertiser changes the type of the Constant Tone Extension after the Controller has synchronized with the periodic advertising, it shall remain synchronized.

Note: A value of 0 (i.e. all bits clear) indicates that the presence or absence of a Constant Tone Extension is irrelevant.

This command does not affect any processing of any periodic advertising synchronization information already received from the peer device, whether or not the Controller has yet synchronized to the periodic advertising train it describes.

The parameter values provided by this command override those provided via the HCI_LE_Set_Default_Periodic_Advertising_Sync_Transfer_Parameters command (Section 7.8.92) or any preferences previously set using the HCI_LE_Set_Periodic_Advertising_Sync_Transfer_Parameters command on the same connection.

If the Connection_Handle parameter does not identify a current connection, the Controller shall return the error code Unknown Connection Identifier (0x02).

Event(s) generated (unless masked away): When the HCI_LE_Set_Periodic_Advertising_Sync_Transfer_Parameters command has completed, an HCI_Command_Complete event shall be generated.

LE Set Default Periodic Advertising Sync Transfer Parameters.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.92

The HCI_LE_Set_Default_Periodic_Advertising_Sync_Transfer_Parameters command is used to specify the initial value for the mode, skip, timeout, and Constant Tone Extension type (set by the HCI_LE_Set_Periodic_Advertising_- Sync_Transfer_Parameters command; see Section 7.8.91) to be used for all subsequent connections over the LE transport.

The Mode parameter specifies the initial action to be taken. If Mode is 0x00, the Controller will ignore the information. Otherwise it will notify the Host and synchronize to the periodic advertising. Mode also specifies whether periodic advertising reports are initially enabled or disabled and whether duplicates are filtered.

The Skip parameter specifies the number of consecutive periodic advertising packets that the receiver may skip after successfully receiving a periodic advertising packet.

The Sync_Timeout parameter specifies the maximum permitted time between successful receives. If this time is exceeded, synchronization is lost.

The CTE_Type parameter specifies whether to only synchronize to periodic advertising with certain types of Constant Tone Extension. If the periodic advertiser changes the type of the Constant Tone Extension after the Controller has synchronized with the periodic advertising, it shall remain synchronized.

Note: A value of 0 (i.e. all bits clear) indicates that the presence or absence of a Constant Tone Extension is irrelevant.

This command does not affect any existing connection.

uint8_t sdc_hci_cmd_le_read_remote_transmit_power_level(const sdc_hci_cmd_le_read_remote_transmit_power_level_t *p_params)

LE Read Remote Transmit Power Level.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.118

The HCI_LE_Read_Remote_Transmit_Power_Level command is used to read the transmit power level used by the remote Controller on the ACL connection that is identified by the Connection_Handle parameter and the PHY indicated by the PHY parameter.

The local Controller may use the remote transmit power level value obtained from a prior Power Change Indication or Power Control Request procedure (see [Vol 6] Part B, Section 5.1.17 and [Vol 6] Part B, Section 5.1.18). If the Controller chooses not to use these prior values, or if no prior value is available for one or more of the remote transmit power level, maximum transmit power level, or minimum transmit power level, the local Controller shall initiate a new Power Control Request procedure to obtain the remote transmit power level.

If the Host sets PHY to a value that the Controller does not support, including a value that is reserved for future use, the Controller shall return the error code Unsupported Feature or Parameter Value (0x11).

If the Connection_Handle parameter does not identify a current ACL connection, the Controller shall return the error code Unknown Connection Identifier (0x02).

Event(s) generated (unless masked away): When the Controller receives the HCI_LE_Read_Remote_Transmit_Power_- Level command, the Controller shall send the HCI_Command_Status event to the Host. When the Controller has determined the remote transmit power, it shall generate an HCI_LE_Transmit_Power_Reporting event with Reason 0x02.

Note: An HCI_Command_Complete event is not sent by the Controller to indicate that this command has been completed. Instead, the HCI_LE_- Transmit_Power_Reporting event indicates that this command has been completed.

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_le_set_path_loss_reporting_params(const sdc_hci_cmd_le_set_path_loss_reporting_params_t *p_params, sdc_hci_cmd_le_set_path_loss_reporting_params_return_t *p_return)

LE Set Path Loss Reporting Parameters.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.119

The HCI_LE_Set_Path_Loss_Reporting_Parameters command is used to set the path loss threshold reporting parameters for the ACL connection identified by the Connection_Handle parameter.

The path loss threshold-based mechanism is described in [Vol 6] Part B, Section 4.5.16. For each zone boundary, the upwards boundary shall equal the threshold plus the hysteresis and the downwards boundary shall equal the threshold minus the hysteresis.

If the Host issues this command with High_Threshold+High_Hysteresis greater than 0xFF or with Low_Threshold less than Low_Hysteresis, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

If the Host issues this command with Low_Threshold greater than High_Threshold or with Low_Threshold+Low_Hysteresis greater than High_Threshold–High_Hysteresis, the Controller shall return the error code Invalid HCI Command Parameters (0x12).

The Min_Time_Spent parameter indicates the minimum time that the Controller shall observe the path loss has crossed the threshold before the Controller generates an event for the threshold crossing. The Host should specify a suitable value based on the connection interval, subrate factor, and Peripheral latency.

If the Host issues this command when path loss monitoring is enabled, the Controller shall override the existing path loss threshold reporting parameters with the parameters provided in this command.

The High_Threshold and the Low_Threshold parameters are common to all PHYs supported by the Controller. However, the Host can reissue this command with suitable parameters whenever a PHY switch is detected.

If the Connection_Handle parameter does not identify a current ACL connection, the Controller shall return the error code Unknown Connection Identifier (0x02).

Event(s) generated (unless masked away): When the HCI_LE_Set_Path_Loss_Reporting_Parameters command has completed, an HCI_Command_Complete event shall be generated.

If the Host issues this command when path loss monitoring is enabled, and if the new parameters mean that the path loss is now in a different zone, an HCI_LE_Path_Loss_Threshold event shall be generated as soon as possible irrespective of the Min_Time_Spent parameter and the timer shall be reset.

If the Host issues this command with High_Threshold parameter set to 0xFF, then the Controller shall not generate an HCI_LE_Path_Loss_Threshold event with Zone_Entered set to 0x02.

Parameters

p_params – [in] Input parameters.
p_return – [out] Extra return parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

LE Set Path Loss Reporting Enable.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.120

The HCI_LE_Set_Path_Loss_Reporting_Enable command is used to enable or disable path loss reporting for the ACL connection identified by the Connection_Handle parameter.

If the Enable parameter is set to 0x01 and no prior LE Power Control Request procedure has been initiated on the ACL connection, then the Controller may need to initiate a new LE Power Control Request procedure on that ACL.

Path loss reporting is disabled when the connection is first created.

If the Host issues this command before it has issued the HCI_LE_Set_Path_- Loss_Reporting_Parameters command on this connection, the Controller shall return the error code Command Disallowed (0x0C).

If the Connection_Handle parameter does not identify a current ACL connection, the Controller shall return the error code Unknown Connection Identifier (0x02).

Enabling path loss monitoring when it is already enabled or disabling path loss monitoring when it is already disabled has no effect.

Event(s) generated (unless masked away): When the HCI_LE_Set_Path_Loss_Reporting_Enable command has completed, an HCI_Command_Complete event shall be generated.

When reporting is enabled and was previously disabled, the Controller shall generate an HCI_LE_Path_Loss_Threshold event as soon as it has a reliable measurement of the path loss. If the Controller has to query the remote Controller for its transmit power level, then it shall generate this event within Tpath_loss_enable from the time it receives a response to its query. Otherwise, the Controller shall generate this event within Tpath_loss_enable from the time the command is issued. Tpath_loss_enable shall be Min_Time_Spent + 6 connection events or, if longer, 2 connection events where the Controller actually receives a packet from the peer, where Min_Time_Spent is specified by the HCI_LE_Set_Path_Loss_Reporting_Parameters command.

After the initial event on reporting being enabled, the Controller shall generate this event each time it determines that the path loss has moved to a different zone and stayed in that zone for Min_Time_Spent.As stated in [Vol 6] Part B, Section 4.5.16, two consecutive events must not indicate the same zone.

Parameters

p_params – [in] Input parameters.
p_return – [out] Extra return parameters.

The HCI_LE_Set_Transmit_Power_Reporting_Enable command is used to enable or disable the reporting to the local Host of transmit power level changes in the local and remote Controllers for the ACL connection identified by the Connection_Handle parameter.

If the Remote_Enable parameter is set to 0x01 and no prior LE Power Control Request procedure has been initiated on the ACL connection, then the Controller shall initiate a new LE Power Control Request procedure on that ACL.

Reporting is disabled when the connection is first created.

If the Connection_Handle parameter does not identify a current ACL connection, the Controller shall return the error code Unknown Connection Identifier (0x02).

Event(s) generated (unless masked away): When the HCI_LE_Set_Transmit_Power_Reporting_Enable command has completed, an HCI_Command_Complete event shall be generated.

When local reporting is enabled, the Controller shall generate an HCI_LE_- Transmit_Power_Reporting event with Reason 0x00 each time the local transmit power level is changed.

When remote reporting is enabled, the Controller shall generate an HCI_LE_- Transmit_Power_Reporting event with Reason 0x01 each time it becomes aware that the remote transmit power level has changed.

The HCI_Disconnect command is used to terminate an existing connection. The Connection_Handle command parameter indicates which connection is to be disconnected. The Reason command parameter indicates the reason for ending the connection and is copied into the error code field of the LMP_DETACH PDU on a BR/EDR connection or the error code field of the LL_TERMINATE_IND or LL_CIS_TERMINATE_IND PDU on an LE connection. All SCO, eSCO, and CIS connections on a physical link should be disconnected before the ACL connection on the same physical connection is disconnected. If it does not, they will be implicitly disconnected as part of the ACL disconnection.

If, on the Central, the Host issues this command before issuing the HCI_LE_Create_CIS command for the same CIS, then the Controller shall return the error code Command Disallowed (0x0C).

If, on the Peripheral, the Host issues this command before the Controller has generated the HCI_LE_CIS_Established event for that CIS, then the Controller shall return the error code Command Disallowed (0x0C).

Note: As specified in Section 7.7.5, on the Central, the handle for a CIS remains valid even after disconnection and, therefore, the Host can recreate a disconnected CIS at a later point in time using the same connection handle.

Event(s) generated (unless masked away): When the Controller receives the HCI_Disconnect command, it shall send the HCI_Command_Status event to the Host. The HCI_Disconnection_Complete event will occur at each Host when the termination of the connection has completed, and on the local Host also indicates that this command has been completed. The Reason event parameter in the event on the local Host shall be set to the value Connection Terminated by Local Host (0x16), while that on the remote Host shall be set to the value of the Reason command parameter. However, if the termination procedure completes because a timer expires and, therefore, the local Controller cannot determine whether or not the Reason command parameter was received by the remote Controller, the Reason event parameter on the local Host should instead be set to the value LMP Response Timeout / LL Response Timeout (0x22).

If this command is issued for a CIS on the Central and the CIS is successfully terminated before being established, then an HCI_LE_CIS_Established event shall also be sent for this CIS with the Status Operation Cancelled by Host (0x44).

Parameters

p_params – [in] Input parameters.

Return values

0 – if success.

Returns

Returns value between 0x01-0xFF in case of error. See Vol 2, Part D, Error for a list of error codes and descriptions.

uint8_t sdc_hci_cmd_lc_read_remote_version_information(const sdc_hci_cmd_lc_read_remote_version_information_t *p_params)

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.1.23

This command will obtain the values for the version information for the remote device identified by the Connection_Handle parameter. The Connection_Handle shall be a Connection_Handle for an ACL-U or LE-U logical link.

Event(s) generated (unless masked away): When the Controller receives the HCI_Read_Remote_Version_Information command, the Controller shall send the HCI_Command_Status event to the Host. When the Link Manager or Link Layer has completed the sequence to determine the remote version information, the local Controller shall send an HCI_Read_Remote_Version_Information_Complete event to the Host. The HCI_Read_Remote_Version_Information_Complete event contains the status of this command, and parameters describing the version and subversion of the LMP or Link Layer used by the remote device.

Parameters

uint8_t sdc_hci_cmd_sp_read_rssi(const sdc_hci_cmd_sp_read_rssi_t *p_params, sdc_hci_cmd_sp_read_rssi_return_t *p_return)

Read RSSI.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.5.4

This command reads the Received Signal Strength Indication (RSSI) value from a Controller.

For a BR/EDR Controller, the RSSI parameter returns the difference between the measured Received Signal Strength Indication (RSSI) and the limits of the Golden Receive Power Range for a Connection_Handle to another BR/EDR Controller. Any positive RSSI value returned by the Controller indicates how many dB the RSSI is above the upper limit, any negative value indicates how many dB the RSSI is below the lower limit. The value zero indicates that the RSSI is inside the Golden Receive Power Range.

Note: How accurate the dB values will be depends on the Bluetooth hardware. The only requirements for the hardware are that the BR/EDR Controller is able to tell whether the RSSI is inside, above or below the Golden Device Power Range.

The RSSI measurement compares the received signal power with two threshold levels, which define the Golden Receive Power Range. The lower threshold level corresponds to a received power between -56 dBm and 6 dB above the actual sensitivity of the receiver. The upper threshold level is 20 dB above the lower threshold level to an accuracy of ±6 dB.

For an LE transport, the RSSI parameter returns the absolute receiver signal strength value in dBm to ±6 dB accuracy. If the RSSI cannot be read, the RSSI metric shall be set to 127.

Event(s) generated (unless masked away): When the HCI_Read_RSSI command has completed, an HCI_Command_- Complete event shall be generated.

Zephyr Write Tx Power Level (per Role/Connection).

This command dynamically modifies Bluetooth LE Tx power level at the antenna given a handle and a handle type (advertiser, scanner, connection).

The Tx power of the Bluetooth LE radio interface is modified for any low-level link by the controller with a high degree of flexibility. The Bluetooth LE link whose power is set is identified based on a handle type (advertiser, scanner, connection) and handle pair.

The role/state defining input parameter is the Handle_Type, whereas its corresponding handle is provided by the Handle input parameter. Note that for Advertisements, the Handle input parameter is ignored in the case that Advertising Extensions are not configured, whereas Advertising Sets are to be identified by their corresponding Handle in case Advertising Extensions are enabled.

The desired transmitter power level for the selected link instance is inputted as Tx_Power_Level. This value represents the actual power level fed to the antenna. When a Front-End Module is used, gain values for the SoC and FEM are calculated automatically to guarantee closest possible match to the value requested by the user at the RF output. The power setup and control can be performed dynamically without the need of restarting the advertiser and scanner role/states. In case of connections, the Tx power changes take effect only if the connections are in a connected state.

The inputs Handle_Type and Handle are passed through as outputs to aid the asynchronous service of the command as well. In addition, the command returns also with the Selected_Tx_Power by the controller which addresses and corrects the possible mismatches between the desired Tx_Power_Level and the achievable Tx powers given each individual controller capabilities.

This vendor specific command is used to disable/enable peripheral latency. Three modes of disable/enable are supported.

In enable mode, the peripheral will wake up every time it has data to send, and/or every peripheral latency number of connection events.

In disable mode, the peripheral will wake up on every connection event regardless of the requested peripheral latency. This option consumes the most power.

In wait_for_ack mode, the peripheral will wake up on every connection event if it has not received an ACK from the master for at least peripheral latency events. This configuration may increase the power consumption in environments with a lot of radio activity.
