- * @ingroup ble_sdk_srv
- * @brief Human Interface Device Service module.
- *
- * @details 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 @ref ble_stack_handler callback.
- *
- * @note Attention! 
- *  To maintain compliance with Nordic Semiconductor ASA Bluetooth profile 
- *  qualification listings, this section of source code must not be modified.
