My drone suddenly goes down and I need your expert opinion to debug the reason using logs
I downloaded the logs and this lines exists in the log:
Test: Event/Failsafe = FAIL - ERR found: FS_BATT
Test: NaNs = FAIL - Found NaN in CTUN.DSAlt
Test: OpticalFlow = FAIL - FAIL: no optical flow data
Test: Parameters = FAIL - ‘THR_MIN’ not found
So most probably this is batter issue, as in other topic someone explained me that the reason is 2S battery. I should use 3s. Please see also my flight logs in that thread.
However I want to debug this using Mission Planner flight logs. And I am thinking to debug by this steps
1)Find the point when drone has crashed i.e. when the altitude dropped to 0.
2) Check the voltage of battery.
Can someone please teach me how to see drone altitude?
And how to see that batter voltage is not enough for drone fly.
