Different behaviors for each flight of the same mission
Hi!
Problem
When I try to execute a mission (that I'll add below), the drone acts differently in every flight. The most weird, and probably helpful behavior, is that the drone stops all of sudden in random locations. Sometimes it stops before arriving at the first waypoint, sometimes between one waypoint and another, sometimes exactly at the waypoint location.
I've executed this mission in 4 different days, in different locations (2 different cities - which implies different 2 missions), at different times (between 11am and 6:30pm), and different weather conditions (cloudy, sunny and windy). One area is above a soccer field and the other one is above a parking lot (the mission below). Both places had no obstacles at the altitude specified in the mission.
Another interesting behavior that only happened in the last day that I tested, is that right before the mission randomly stops, the gps count drops to 0 and right after gets back to how it was before (between 11 - 17).
After noticing this, I decided to test with the Phantom 4 Pro V2. Actually, I've tested with two Phantom 4 Pro V2, and both of them worked perfectly every single time.
Do you have any idea on what may be happening?
