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?
The Forum has this fancy search function on the top right. I guess we have to make it big and flashy so that people will see it.
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:
