This module implements the Link Loss Service with the Alert Level characteristic. During initialization it adds the Link Loss Service and Alert Level characteristic to the BLE stack database.

The application must supply an event handler for receiving Link Loss Service events. Using this handler, the service will notify the application when the link has been lost, and which Alert Level has been set.

The service also provides a function for letting the application poll the current value of the Alert Level characteristic.

Note: The application must propagate BLE stack events to the Link Loss Service module by calling ble_lls_on_ble_evt() from the SoftDevice Event Handler callback.
