3 * File Name : atp_gsm_bt_api.c
4 *
5 * This file handles all the interface between GSM AT command handler or Data handler
6 * and the BT protocol stack. It has 2 main functions:
7 * - get the events coming from Bluetooth ATP in direction of GSM, analyse them and
8 * call the proper function of atp_gsm_gsm_api.c
9 * - offer function to GSM so that GSM can use services of the BT PS
10 *
