Im not able to receive video or telemetry

  • Make sure you have added video and telemetry port to your firewall rules.
  • Verify that you have proper connection with your flight controller. You can run the connection test from the Flight Controller page.
  • If you have changed the default ports for video 5600 or telemetry 14550 you need to change this on your ground control station device as well.

No Mavlink Heartbeats received in UAVcast-Pro

  • Make sure the configuration in UAVcast-Pro Flight Controller page reflects the settings in the Flight Controller. You can see the FC setttings using Mission Planner => All parameters list => search for Serial0 (USB) or Serial1 (Telem1 port) or Serial2 (Telem2)
  • Make sure you are using a good USB cable with large cross-sectional area to minimize the voltage drop supplied to Fligth Controller.
  • If you are connected by GPIO pins, make sure you have connected the ground, rx, tx wires correctly.
  • Make sure you use default configuration in Flight Controller (Ardupilot, Px4) for UART / Telemetry ports.

Cant receive video, but telemetry works

  • [PiCam] Please make sure you have enabled PiCam in the Raspberry config raspi-config
  • [Logitech cams] Check logfiles and see if there is any errors. If you see Internal data stream error its most likey a unsupported resoultion or fps. Try play with those settings.
