Bluetooth no connection Thinkpad T420s -> Onkyo TX-8150 Receiver

Hi,
I wonder how/if it is possible to connect to my Receiver TX-8150 via Bluetooth from a Thinkpad T420s

What works:

  • I can connect to this receiver using Windows 7
  • I can connect to other Bluetooth-Devices (for example to a blackberry D50 or a Gear4 Bluetooth-Speaker) from LEAP 42.3

So Bluetooth works in general, just the Onkyo Receiver TX-8150 is not found.

Any hint to solve this problem?

Franz
