Can somebody help me with using the telemetry port as GPS port on the Pixhawk? Any help is much appreciated Please Whatsapp me at 9846710101

go to full param tree... search serial 1 protocol or serial 2 protocol_...depending on which telemetry port u want to change. change option to GPS   ie change to 5

I don't think u can us telemetry port for gps but you can use the serial port for gps.

Just check the official ardupilot docs.... Here is the link....
