Bluetooth input/output?

So, I have this bluetooth earpiece I wanted to use for input audio and output audio with mycroft, but I have no idea how to set it up, as when I connect, I do not hear anything and get no response from the wake word

Look for the device number of the earphone and add it to configuration.

Step 3 of this wiki page provides the details. Look for your earphone instead of the loopback device that wiki page refers to.

I were you able to do it ? I have a UE boom but I am not able to make it work. I had problem to connect the Bluetooth alone. And didn’t find where to change in the config files.
Is someone could give me more infos?

Thank you very much
