Hi Everyone,
yesterday I had an incident flying my copter: hovering in Loiter at about 1 meter it descended quickly and hit ground.
After log investigation I found the reason of that drop: barometer wrongly reported that the altitude increased rapidly, so the Loiter controller parried this with a descend.There was no any altitude change. Copter was in several meters from me and hovered very stable. AccelZ values also does not show any moving.
It was almost 30-minutes flight and inspecting baro readings of whole flight I see very smooth and adequate baro values. Exept the one in the end of the flight that caused the hit.
So I attempted to figure out what affected Baro. And I found another anomaly in my log right at the same time - there is a rapid peak of current up to 23A logged. I believe this peak is not real because there is no voltage drop as it usually happens:
Moreover, I recall that when I armed my copter at the begin of the flight I saw that it was a 6-7 Amps of current when motors were not rotating at all! (I'm using MOT_SPIN_ARM = 0)
It was the same anomaly with curent and baro readings:Long story short: I have no idea what was that and how can I prehen that to happen it the future.
Any thought are very appreciated!
