This application uses the ADL GPRS service to setup the GPRS bearer, open
the session and the FCM flows with the ADL GPRS service.
The +GSET command has to be used to set-up the GPRS connection.
These command parameters are saved in non volatile memory.
Then, with the +WDATA command, it sends ping requests to an IP addr and waits the reception of the
answers.
