It’s in the correct port and correct orientation. I restarted everything this morning to check the Mavlink Inspector and the pressure sensor is working normally again. I’d rebooted the vehicle and QGC laptop multiple times yesterday trying to troubleshoot this with no luck. Now I can’t get it to fail again. I’ve gently tugged the wires, put the electronics enclosure in different orientations and everything continues to work perfectly.
I’ll leave the vehicle powered up today to see if the problem returns. I assume everything but the thrusters should capable of indefinite operation in air?
