I added functionality to get the RSSI, BER, and Cell Neighbor for reporting connection issues to M2X

Dependencies:   WncControllerK64F

Revision:
18:198e9b0acf11
Parent:
12:0071cb144c7a 
Updates to mbed os resulted in mutex.h going away and rtos.h needed to be used; This fixes the Mutex typedef failure.  Also cast data buffers from 'char *' to (const std::uint8_t*) to conform with Fred's changes in WncController
