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.
