Sadly I didn’t play around with Bluetooth yet. Because the openHABian base is a very minimal Raspbian, there are some differences. I hope we can find a solution that can then be included in the openHABian image by default! So please try and give me some feedback!
Just so you know: You could always just install a standard Raspbian (Lite) system and add openHABian to the mix following these few steps: http://docs.openhab.org/installation/openhabian.html#manual-setup
