Hi, I was reading and I would like do something similar. I want start to run this [script](https://gist.githubusercontent.com/patrickelectric/17093de541b533c9afd7fb57e2c96a91/raw/13e43c36466fed9c08309f34fc78034243673329/simple_mavtester.py) directly in the RPi from the BlueROV2, without lose the telemetry and video in QGC. But when I do, the script remains frozen and only I see this result: " pi@raspberrypi:~ $ python test\_auv.py Waiting for APM heartbeat " The script to split the telemetry is for default: " # this starts mavproxy so that the serial link to the companion computer (on /dev/ttyACM0) # is available to a companion computer and external GCSs via UDP. This broadcasts so that # multiple IP addresses can receive the telemetry. # For PixHawk or other connected via USB on Raspberry Pi cd /home/pi mavproxy.py --master=/dev/serial/by-id/usb-3D\_Robotics\_PX4\_FMU\_v2.x\_0-if00,115200 –source-system=200 –cmd=“set heartbeat 0” –out udpin:localhost:9000 –out udpbcast:192.168.2.255:14550 " I try change in my code of ‘test mavlink messages’ with: master = mavutil.mavlink\_connection(‘udp:localhost:14550’) or master = mavutil.mavlink\_connection(‘udp:192.168.2.1:14550’) or master = mavutil.mavlink\_connection(‘udp:192.168.2.2:14550’) or master = mavutil.mavlink\_connection(‘udp:localhost:9000’) But, none works. Can you help me please? Thanks a lot! Greetings! --- _[View the full topic](https://discuss.bluerobotics.com/t/autonomous-bluerov2-mavlink-ardusub-help/1761)._
