I have been trying to get 4 Pixhawk systems ready for flight. In each case I, loaded the current stable firmware, 1.7.3.
However, they won't work with QGroundcontrol 3.3.2. We can't get them to work properly. We tried going back to prior stable versions of PX4 (1.7.0), but with limited success.
It seems to us that there is a basic incompatibility between the two systems.
Is anyone else having trouble running PX4 with QGC?
