I also don't know whether bluetooth (rfcomm) communication will work out 
of the box or not. I know from Nick that the BLE communication requires 
some small changes to protocol, and to make things even worse there are 
several different BLE variants. So BLE support will certainly need some 
more work first. But for rfcomm, I have no idea. I don't even know 
whether the device support it.

So for the time being, I think I'll postpone applying this patch until 
someone can conform it does indeed work. Otherwise it will create false 
expectations for users.

Note that there are some more bluetooth capable models as well:

  * Aeris A300CS
  * Oceanic Pro Plus X
  * Oceanic VTX
  * Aqualung i300C (not supported yet)
