LibreELEC on RPi 400 does not find any Bluetooth device

dumetrulo · December 28, 2020 at 4:36 PM

Sorry if this is actually already posted somewhere but I was unable to find anything that helped. I installed LibreELEC 9.80 nightly 20201225 for use with a Raspberry Pi 400, and found that it does not find any Bluetooth devices. Bluetooth service is on, and Bluetooth audio (connect to external BT speaker, and play sound on it) works fine on RPiOS. Any ideas?

You probably need a firmware update.

So how does it work? Do I download the /firmware/boot folder, and drop its contents into the SD card's /boot partition?

I'm not sure whether this issue has been fixed (new hardware). I've been informed the dev - stay tuned.

I just received some feedback. Bluetooth settings need an overhaul. So you will not get a fix for this very soon - sorry.

So however it works with the update, it is not likely to fix the issue?

On the other hand, how come it does not work if the RPi 400 is 'just' an RPi 4 in a keyboard? Makes no sense to me, unless it is known that Bluetooth also does not work on the RPi 4 with LibreELEC.

Firmwares and kernel are up to date in nightly images, the problem is that the bluetooth part in LibreELEC settings is currently broken - this afects all platforms, also x86 etc. No ETA for a fix, it's being looked into.

BTW: The Pi 400 isn't a "RPi4 in a keyboard", it's a bit different in several details - for example it uses a different WIFI/BT chip (which is why you won't get WIFI/BT in LE9.2).

so long,

The settings add-on was using python dbus, which worked fine until LibreELEC 9.2.x

However python dbus is broken on LibreELEC 10 (currently available as 9.80.x nightlies)

The settings add-on is currently being rewritten to switch from python dbus to dbussy/ravel

The networking part is nearly done

The bluetooth part will be next, but will likely need a couple of weeks of work

In the meantime, you could try using CLI tools

HiassofT and thoradia. Thanks for taking the time to explain and for suggesting a temp workaround.

Thank you thoradia. Any more details on configuring bluetooth via CLI?

LongMan · December 30, 2020 at 7:49 PM

ssh into your pi

bluetoothctl - to start the bluetooth control program

power on - to enable bluetooth service.

Put your remote in discovery mode

scan on - scan for pairable devices. The address, <dev>, and device name will be listed. Use the address, <dev> to pair

pair <dev>

trust <dev> - if you or your device needs it.

Exit - Quit bluetoothctl

Exit - end ssh session

Thank you LongMan! I had this on the backburner for now so I didn't get around to working with the commands yet. Plus, if connecting to the speaker is not automatic after pairing, there is little use in trying this, and I would rather wait for a fixed version of the UI.

Speaking of: does anyone have any idea when a fixed version might become available?

dumetrulo · February 24, 2021 at 6:15 PM

Does anyone know whether there has been any progress with this issue?

dumetrulo We have no ETA for this. Stay up-to-date with RPi4 nightly builds and hope for the best. This is pretty new hardware.
