Hi guys. First things first. Sam, thanks a lot for your AWESOME work for the RPI community.
Ok I’m streaming audio using bluetooth to my Bose QC35 headphones. A tip about this.
You have to add this line ControllerMode = bredr to the file: /etc/bluetooth/main.conf
Otherwise you couldn’t pair the QC35. After restarting the bluetooth system (or your RPI) you can comment that line or remove it, the problem happens just during the pairing process.
A couple of months ago I had yo disable the internal bluetooth device in my rpi3 (adding dtoverlay=pi3-disable-bt to the config.txt file) and use an external bluetooth dongle because nothing worked with the internal one.
Has that been fixed with the last version of OSMC? (krypton)
PD: Modify config.txt using the OSMC interface, avoid changing the file from a command line interface
