Detailed Description

Human Interface Device Service module.

This module implements the Human Interface Device Service with the corresponding set of characteristics. During initialization it adds the Human Interface Device Service and a set of characteristics as per the Human Interface Device Service specification and the user requirements to the BLE stack database.

If enabled, notification of Input Report characteristics is performed when the application calls the corresponding ble_hids_xx_input_report_send() function.

If an event handler is supplied by the application, the Human Interface Device Service will generate Human Interface Device Service events to the application.

Note
The application must propagate BLE stack events to the Human Interface Device Service module by calling ble_hids_on_ble_evt() from the SoftDevice Event Handler callback.
Attention! To maintain compliance with Nordic Semiconductor ASA Bluetooth profile qualification listings, this section of source code must not be modified.

Function Documentation

uint32_t ble_hids_boot_kb_inp_rep_send ( ble_hids_t p_hids,
uint16_t  len,
uint8_t *  p_data 
)

Function for sending Boot Keyboard Input Report.

Sends data on an Boot Keyboard Input Report characteristic.

Parameters
[in]p_hidsHID Service structure.
[in]lenLength of data to be sent.
[in]p_dataPointer to data to be sent.
Returns
NRF_SUCCESS on successful sending of the report, otherwise an error code.
uint32_t ble_hids_boot_mouse_inp_rep_send ( ble_hids_t p_hids,
uint8_t  buttons,
int8_t  x_delta,
int8_t  y_delta,
uint16_t  optional_data_len,
uint8_t *  p_optional_data 
)

Function for sending Boot Mouse Input Report.

Sends data on an Boot Mouse Input Report characteristic.
