PS4 controller with Bluetooth: Only the touch pad sends events?

Hello,

I'm currently trying to get my PS4 controller to work via Bluetooth.

My kernel is:
$ uname -a
Linux manuelspc 4.3.3-3-ARCH #1 SMP PREEMPT Wed Jan 20 08:12:23 CET 2016 x86_64 GNU/Linux

If I run "evtest" on the event device, created by the controller, then I only get events if the touch pad is touched. Even pressing the touch pad doesn't create a event and all other buttons and sticks don't send events either.

What's the reason for this? If I connect via USB, I don't have any issues and all buttons and axis work well...

Thank you very much in advance.

Best regards,

Manuel
