I have PIX4d capture 3.6.1 running on Samsung Tab s2 Android 6.0.1.
/controller links ok to drone. Grid mission inputs to drone OK. Mission take off is normal. Drone flies to beginning of grid, orients itself, starts forward and takes one photo, then immediately drops communication and climbs to RTB altitude, but holds itself in place. I have to manually fly it back to its take off point.
This stuff had been working O, until I installed the DJI Go 4 app, which demonstrated the same problem.
I did a complete system reset on my tablet, and reinstalled the original DJI app (3.1.3)
How do I get this system back in to operation?
