Bluetooth not working on ASUS ROG M8F Ubuntu 22.04.3LTS

  • 772

This question has been asked several times but no answers were posted.

Cannot turn on Bluetooth on Ubuntu 23.10 (Asus ROG ROG Flow X13 GV302XV) seemed like a great answer but didn't work in my case.

sudo dkms install btusb/4.1

failed at the end of the build. However, this answer was aimed at a problem with a USB BT connection. In my case, bluetooth is implemented on the mobo.

$ sudo service bluetooth status

Shows that the service is running ok. But.... there is no bluetooth icon in the top right status bar (as it is on my M8H machine using a BT dongle)

Bluetooth has worked on this machine previously but that could have been when earlier versions of Ubuntu were installed.

The mobo specs are bt v4.0/3.0+HS on an Intel Z170 chipset.

The problem: In Ubuntu's BT settings, bluetooth is turned on and the devices search wheel is spinning but no devices are ever found. This is true even if I install a BT dongle. The desktop right beside it is an ASUS ROG M8H mobo with no integrated BT. With a dongle installed it immediately connects to selected BT devices. Both machines are running identical versions of Ubuntu.

ASUS has firmware for bt but only in Microsoft format. They are clear that they do not support *NIX but obviously there are many of us running Ubuntu on ROG machines without problems.

I'd like to be able to run just one speaker via BT on each desktop instead of having four speaker sets, one hardwired to each machine. Yes, I know I can only have the device paired to one PC at a time.

sudo dmesg|grep Blue
[165140.288091] Bluetooth: hci0: unexpected event for opcode 0x2005

bluetoothctl fires up but I don't understand enough about that tool to use it productively. Looks like it's working ok though. Just no devices are discovered (and yes, the wifi antenna is connected. The manual sort of implies that this is needed for BT)

As expected for an onboard BT capability

    Your driver was installed successfully. You just need to enable the device:

    1. rfkill unblock all
    2. hciconfig and see see that the "DOWN" turns into "UP RUNNING PSCAN"
    3. bluetoothctl power on
    4. bluetoothctl scan on and see nearby devices

    The absence of dmesg and journalctl errors mean that nothing went wrong. You have driver=btusb so the driver loaded and detected the internal device properly. The problem was the "DOWN" in hciconfig, and the corresponding thing you would see in rfkill list.
