Hi, I'm using the Linklt Assist 2502 GPS example code and in the monitor appears "GPS.c: 79 open failed". I haven't made any changes in the code, it is exactly the same of the example. When it pass througt the function gps_power_on in the monitor I got "GPS open success", but in the function gps_callback I got "open failed". Could please somebody help me? What can cause this condition and what can I do to fix it?
