4.3.9 Application Initialization
A WristApp is initialized for the first time when the current communication session is completed. The
WristApp’s background handler is processed with the system event COREEVENT_INIT. This will allow
the WristApp to setup the required parameters in the ASD section. It could also use this time to update
ASD information from the database header info if available.
