Re: No log_packace with the new library
Marcus do you mean the output of my application?
With new I mean the last version, with old I mean the version before the hover mode.

Re: [SOLVED] Crazyflie tilts to M4 side when taking off
I have the same behavior. But In my case I don't think it is a problem of the ontroller because i'm using my own code where i send exactly the commands. I think it could be a problem of the IMU that is not perfect calibrated.
