Currently using 2 Digi Xtend 900 radios and trying to connect to a Pixhawk running either Mavlink or Mavlink 2. Any settings or suggestions would be appreciated. When I connect with QGroundControl, the radios act like they are talking as we get RSSI lights, but I am getting no data to QGroundControl.
I would strongly suggest looking at voltage levels on your UART interface. Also make sure that your have the Tx and Rx lines correct. The radios function as a Cross over cable in the air.
