I’m need some help understanding the logic between running two telemetry ports on a Pixhawk 2.1. On telemetry one, I’m running a 4G modem on on MAVLINK 2. On telemetry two, I’d like to run a RFD900X on MAVLINK I. How does the Pixhawk determine what telemetry port to use, if they both have excellent communications? If I lose 4G connection, should it automatically revert back to the RFD900X? Vice versa? How would I set it to swap to the other if one port looses connection? I’d appreciate any help.
