Alt.Hold not working correctly / bad baro values

Hello,
I now have purchased a CF2, and it is a very cool quad, but I can not get the alt.hold working.

It hovers just centimeters over ground and does little "jumps", I guess due to the ground effect.

Everytime when I get some height (~2 meters) and press the "assisted control" button on my controller, it drops down to the ground and hovers there.
(The button itself is working, otherwise the thrust would drop to zero).

Is this a common problem?
So far I found nothing.

How can I read the raw baro-values? in the cfclient under baro is "z.stateEstimate", which is after sensor fusion I guess.

Hi,

this behavior looks like the altitude hold is not actually enabled in the Crazyflie. There has been a bug with that in the client previously, what version of the client are you using?
