LE Read ISO TX Sync.

The description below is extracted from Core_v5.3, Vol 4, Part E, Section 7.8.96

This command is used to read the TX_Time_Stamp and Time_Offset of a transmitted SDU identified by the Packet_Sequence_Number on a CIS or BIS identified by the Connection_Handle parameter on the Central or Peripheral.

The Packet_Sequence_Number parameter contains the sequence number of a transmitted SDU.

The TX_Time_Stamp and Time_Offset parameters are described in [Vol 6] Part G, Section 3.3 and [Vol 6] Part G, Section 3.1 respectively. When the Connection_Handle identifies a CIS or BIS that is transmitting unframed PDUs, the value of Time_Offset returned shall be zero.

If the Host issues this command with a connection handle that does not exist, or the connection handle is not associated with a CIS or BIS, the Controller shall return the error code Unknown Connection Identifier (0x02).

If the Host issues this command on an existing connection handle for a CIS or BIS that is not configured for transmitting SDUs, the Controller shall return the error code Command Disallowed (0x0C).

If the Host issues this command before an SDU has been transmitted by the Controller, the Controller shall return the error code Command Disallowed (0x0C).

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

Parameters

[in]	p_params	Input parameters.
[out]	p_return	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.
