I have found a bug with my Phantom 3 Pro. If the switch is in the F-GPS position and I try and upload a mission with the Capture App, then the DJI Control app crashes. Sometimes this results in the Capture app crashing as well. It looks as if the connection with the drone is lost too as it takes a couple seconds for it to be re-established.
We would recommend the following workflow:
- Set the F mode.
- Turn on the drone.
- Turn on the remote controller.
- Start Pix4Dcapture from scratch.
This should prevent the scratch form happening.
Let us know if it persists (here or in the current email discussion).
