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.

As far as the version of th cflib and the firmware it is before addition of the hover mode, but I don't know where i can find the correct numb...

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.
