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....
