This group includes functionality of registering the BLE Events from profile/service/application.
BLE-Manager checks the registered callbacks with respective events.
The BLE Profile or BLE Services can subscribe the events like GATT Server Event, GATT Client Events, GAP Events, L2CAP Events, HTPT Profile Events, DTM Events and CUSTOM Events by registering its call-backs to BLE-Manager.
If the event and registered callbacks is valid ble manager will calls the respective call back to handle the events. The more number of profile can also subscribe the same event for process. ex. If BLE battery service and BLE blood pressure profile are present in the same application then it can subscribe the same events.
