Hello,
on my pixhawk 3 pro running ardupilot flight stack i’m struggling to use telemetry port 3/4. I’ve set serial4/5 to baud to 57600 and protocol to mavlink, but no data is sent through the telemetry radio. The radios work without any issue if it is connected to Telemetry port 2 which has the same configuration.
Has anyone seen this/have a solution on how this can be done?
