Internal Bluetooth

Enabling internal bluetooth

If bluetooth is disabled, enable it.

mount -oremount,rw /boot
sed -i 's/dtoverlay=disable-bt/#dtoverlay=disable-bt/' /boot/usercfg.txt
mount -oremount,ro /boot
savereboot.sh

The Bluetooth controller is not automatically discovered on the UART. Test attaching it and check that the controller is found.

btattach -B /dev/ttyAMA0 -P bcm -S 115200 -N &
/etc/init.d/bluetooth start

After that bluetoothctl list should list your bluetooth controller.

If the interface is discovered after the attach, you can make attaching persistent by uncommenting the line next to "rpi bluetooth" in /etc/mdev.conf.

sed -i 's/^#ttyAMA0/ttyAMA0/' /etc/mdev.conf
