in 2 missions the drone (DJI Phantom 4V2) stopped in the middle of the work and did not continue. I had to bring it down and at each take of the mission it always stopped in the same spot. What can it depend on?
Welcome to the forum Ruberto
A couple of things you can check quickly;
- Trees, aerials, towers in your flight path - if you drone flies towards these during a flight the sensors will stop the drone moving forward.
- DJI Geofenced areas - check if you are flying near / adjacent to any airfield / airport / military NFZ areas - some DJI closed zones can be unlocked - review the link to this video if this is the case; How to Unlock DJI Geofencing Using the GEO System - YouTube
These are the two issues I have worked through.
Other members may have some alternative solutions.
Good stuff! You might also try turning off obstacle avoidance and keeping the camera pointed away from the sun as you start. We have seen 360 panos fail a bit lately and a couple of restarts usually gets it but there is definitely something going around.
