If you hold the copter in your hand this is also expected, the controller will try to compensate more and more and the extreme is to stop one motor. Have you double checked the propellers? If it flips over it might be that one propeller is not of the right kind. Yes the latest binary is from Februar...

Hi, This is expected and normal: the gyroscopes will drift but pitch and roll can also be measured by the accelerometer that is used to cancel the gyro drift. YAW being around the gravity acceleration it cannot be measured that way and we have no way to cancel the drift. We had a bug in the gyro bia...

Hi,

If you let the Crazyflie still on the table does the "actual" yaw moves a lot or does it stays pretty stable?

In the current form the Kalman filter is mainly aimed at position estimation. However it seems to be doing a good job without position input so this is to be tested and hacked

Hi Wolfgang,

A little while ago I pushed a "de-bricking" script that uses a Rasperry pie on the Crazyradio repos: https://github.com/bitcraze/crazyradio- ... bootloader.

Otherwise I will try to clean-up my code and push an Arduino flasher during the week.

Hi, The CPU goes in STOP mode when sleeping which means that pressing the button wakes it up from reset and the _MBS firmware is then started in main() at startup and then wait to see for how long the button stays pressed. The code to setup the STOP mode and the wake-up pin is part of the crazyflie2...

The message seems to be for python2.7 so I am not sure it applies here, unless it has not been updated for python3.5. I have no idea why it is not working for you as I never had this problem (it is working here so this is the hardest kind of problem to debug...). Have you tried to uninstall/reinstal...

Thanks for the precision, I am not surprised for the log since it was not designed to be used for such hard-realtime case. Your solution sounds good to me. it is good to know that such things are possible. Is there a reason why you chose an off-board approach instead of coding directly un the Crazyf...

Hi, Are you sure your phone is not connected via bluetooth at the same time as the VM? If this would happen the result would be similar to what you are describing: both clients would trie to send different setpoints and because one of te client is sending thrust at 0 it would limit the thrust. /Arnaud
