Hi there, I am running Cube PixHawkPX2, Raspberry pi tied to Telem2 and running Mission Planner Software ArduPilot, I. Attempting to run the maxproxy.py --master=/dev/serial0 --baudrate 115200 --aircraft MyCopter I get: Waiting for hearbeat from /dev/serial0 and finally get: MAV> Link 1 down I also found the Mission Planner for Serial 0. I modified this to be 1 for MAV Link …but still does not work.
