Jittery orientation after upgrading 2.8.1 to 2.9.1

Posted by Andrew Chapman on February 11, 2013 at 9:08pm

Sorry if the answer is buried in the monster 2.9 release thread (there's no search within a thread function here is there?).

After upgrading from 2.8.1 to 2.9.1 my quad now reports a very jittery artificial horizon when connected to the Mission Planner (video capture from MP attached).

This is with the quad sitting on a stable, level surface, no battery plugged in, just a USB connection to the laptop. I did a CLI reset and accelerometer calibration.

Anyone else experiencing this?

    I think from this video it is something to do with not having a great GPS fix indoors

    exactly what I was going to post this morning.

    Something very similar. Just upgraded to 2.9.1 and I find that the vertical speed indication is fluctuating +/- 0.3m/s and the indicated height +/- 1,5m. This is with the quad on the bench connected in the same way as your self. This is on an APM 1.4.

    So I went back to 2.8.1 and all is stable again.I have good vibration levels for 2.9 apparently. (They are within limits)
