I am using a raspberry pi. Discovery and connecting with blueZ works like a charm. My Pi runs the stated BlueZ 5.44.

That part of the error message is suspicious: according to signature None: <class 'TypeError'>: Expected a string or unicode object. Looks like some type couldn't be resolved.

Which adapter name does your Bluetooth adapter have? Is it hci0?

chbardel commented 7 years ago

The name is hci0 thats right! I really dont know where this is coming from. I followed the instructions one by one and on bluetooth side it is no problem to find and connect to the nuimo via CLI.

After a reboot everything works fine now. Always the same stupid thing, while the sophisticated developers mind produces the complexest of possible errors.

Glad it's working now. Thanks for your feedback!
