I have earlier tested Dronedeploy for small areas without any problems. Two days ago it was first time I tried to map a little larger areas, with about 15 minutes of mission length. Both saved offline missions and areas set locally. However, the mission process stops at the “starting mission” screen. I also tried setting small default sized areas, that worked fine. But when i set the altitude to over 100 meters, the mission progress was stuck at “starting mission” again.
Today I tried again with my mobile device connected online. Longer missions still don’t work. Sometimes it was stuck on the “starting mission”, sometimes it returned error 3 or error 12, telling to try smaller missions if using older firmware.
I have the Phantom 3 Pro with the newest firmware.
Any ideas what might be causing the problem?
