I was playing a bit with bluetooth:

root@NBG8715:~# rfkill list

0: phy0: wlan
        Soft blocked: no
        Hard blocked: no
1: phy1: wlan
        Soft blocked: no
        Hard blocked: no
2: phy2: wlan
        Soft blocked: no
        Hard blocked: no

root@NBG8715:~# bluetoothctl list

So the built-in bluetooth is not exposed to the OS it seems.

If I insert an external USB BT stick I get:

root@NBG8715:~# rfkill list

0: phy0: wlan
        Soft blocked: no
        Hard blocked: no
1: phy1: wlan
        Soft blocked: no
        Hard blocked: no
2: phy2: wlan
        Soft blocked: no
        Hard blocked: no
3: hci0: bluetooth
        Soft blocked: no
        Hard blocked: no

root@NBG8715:~# bluetoothctl list

From there I don't know how to dig further. Because it this indicates sth. other is wrong. I could imagine a conflict with DBUS and UBUS. Or lacking firmware for the device itself.

While this is a nice to have feature because Bluetooth Tethering is less power consuming I would not insist to make it work.

I've digged up this which makes me think it could be more complicated to get BT working:
