Detailed Description

Alert Notification module.

This module implements the Alert Notification Client according to the Alert Notification Profile.

Note: The application must propagate BLE stack events to the Alert Notification Client module by calling ble_ans_c_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.

Parameters

[in] p_ans Alert Notification structure. This structure will have to be supplied by the application. It identifies the particular client instance to use.
