Just hooked up a Dragonlink microRX. Attempting to connect over the DL modem and I get this error. RC inputs work fine, just not the modem/MavLink data. Any idea what this Internal Error is so I can narrow this down a little?
There is a wiki page explaining the ArduPilot internal errors. Have you read that?
Is there anything after that shown on screen? Like “I:1234” or something?
Copy and paste from the messages tab.
Couldn’t find anything that addressed the internal error. Ended up being that the instructions for the DragonLink were incorrect and the USB port configuration should be ‘radio modem’ instead of ‘MavLink’.
