bluetooth not detected

[tazzkiller]

BTGamepad always return " Please turn on bluetooth " after the choice of gamepad or keyboard on ubuntu 16

ran into the same thing. Looks like in the newer version of pybluez, they took out some of the functions like "DefaultAdapter", so it errors in the try/catch as "Please turn on bluetooth".

Is there a known version of pybluez where this works or an update coming. This looks pretty polished and I'd like to see it working.

I met the same problem.

I'm also interested in seeing this work. I'll see if I can modify it myself and make a pull-request.

Fixed that problem, so I'll include the patch. Unfortunately since this was written in such an old version of Bluez I'm sure there's other problems.

For now I think this is the best option:
