upgrade to 3.1 and autotune worked great! I just manually lowered the Stabilze P values to fly “smoother” and recently also the Rate P values due to strong decent wobble. Awesome now.
BUT: I have a problem since upgrade to 3.1 / (after autotuning?) with my GPS:
First I got GPS error messages not being able to arm- that just happened once- but this is gone now.
Flies great BUT
I am not able to LOITER (did not try other GPS modes)- copter just flies away in some (random) direction.
Calibration of compass is perfect- vibration levels really low, Alt hold also great. (at least from my understanding)
I already tried changing the PID settings for loiter- no difference (more aggressive fly away behavior but still no holding position AT ALL) I looked at the logs- no idea- just low sat count (8) and hdop could be better.
PLEASE, please have a look at my logs (have more but too big to upload here) because I am stuck and one big reason for arducopter is GPS…
I am not planning to rely on it but would feel MUCH better to have it working on that expensive quad “just in case…”
I have no idea what might cause the issue, so any help would really be appreciated!
