Hi,
the internal BT device of my Pi3 is not that powerfull as a external USB BT dongle.
I wan’t to make sure that it is disabled completely to save power. (Pi connected in the car)
Is it enaugh to switch the default BT controller to the USB BT dongle with bluetoothctl or is there another option to disable the internal BT device?
regards ben

Add dtoverlay=pi3-disable-bt to /boot/config.txt. You need to be on the latest OSMC version for this to work.
Then run
sudo systemctl disable brcm43xx.service
thank you @fzinken for the hint. I searched but haven’t found this thread. will try it and reply, but I think that will work!
You can disable bluetooth through a device tree overlay in config.txt. See:
