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 from the ble_stack_handler callback.
Attention! To maintain compliance with Nordic Semiconductor ASA Bluetooth profile qualification listings, this section of source code must not be modified.

This function will erase the flash page (if the data to store are diferent than the one already stored) and then write into flash. Those operations could prevent the radio to run.

Note
Do not call this function while in a connection or when advertising. If you do, the behavior is undefined.
