Hi,

my config : the plane : holybro px 4 arduplane last version.
raspberry pi 5 connected to tailscale
usb cam

               ground station 1 : on pc connected to tailscale 
                                            mission planner  udp port 14550 
                                            ok

                ground station 2 : raspberry pi 3b+ connected to tailscale
                                              python and mavlink installed
                                              mission planner installed
                                              unable to get the mavlink stream

i try to connect to mavlink with this command :

mavproxy.py --master=/dev/ttyAMA0 --baudrate 57600 --out 100.78.14.39:14550 --aircraft MyCopter
where 100.78.14.39 is the ip adress of the pi 5 in the plane . it doesn’t work : AMA0 no such file.

if i try :slight_smile:

mavproxy.py --master=/dev/serial0 --baudrate 57600 --out 100.78.14.39:14550 --aircraft MyCopter

i get : link 1 down

That’s not correct. You have the --out and --master confused. Try:

mavproxy.py --master=100.78.14.39:14550 --aircraft MyCopter

I’m not sure I understand. You have a raspberry pi 5 on your plane, and it can’t connect to the flight controller via Mavlink over UART? Or is your issue that you can’t connect a Ground Station Raspberry Pi to the Pi on the plane?
