iCade/bluetooth controller + iOS 9.2

I have an iCade bluetooth controller. It works perfectly with iOS 8 and 9 and even 9.1.

But since 9.2 I can connect the controller to my iPhone 6s, but non of button works, phone has no reaction.

I checked with another phones and iPads, all 9.2 devices don't work, however 9.1 works.

Does anybody have this problem? Are there any solutions?

Thx in advance
