+* File Name : atp_gsm_bt_api.c
+*
+* This file handles all the interface between GSM AT command handler or Data handler
+* and the BT protocol stack. It has 2 main functions:
+*	- get the events coming from Bluetooth ATP in direction of GSM, analyse them and
+*	  call the proper function of atp_gsm_gsm_api.c
+*   - offer function to GSM so that GSM can use services of the BT PS
