I’ve got open-hd setup and working for video transmission but I’m having a few problems getting mavlink data to drive the OSD from my flight controller. I’ve connected the pixracer telemetry port 1 to the pi0 uart0 (pins 8 & 10) and confirm with a scope that the tx & rx pin are the correct, also tried changing the baud rates.
Any ideas what could be causing this problem or ways to debug the telemetry data?
in the air:
flight controller: pixracer (ardupilot installed)
mediatek 8812bu (didn’t think this would work but seems ok on the ground station)
