[SOLVED] Bluetooth doesn't turn on in relatively fresh install.

ItsFireStorm · 2025-05-11 15:49:26

I recently re-installed Arch on my PC and wanted to get Bluetooth on so I could connect my Controller, but at the moment of turning it on via bluedevil, it reported nothing, didn't scan, didn't tell me it was on, etc.

I made sure to check that the bluetooth service was active with sudo systemctl status bluetooth.

● bluetooth.service - Bluetooth service

             └─596 /usr/lib/bluetooth/bluetoothd

I also made sure that the btusb module was loaded (lsmod | grep btusb).

btusb                  86016  0
btrtl                  32768  1 btusb

bluetooth            1150976  15 btrtl,btmtk,btintel,btbcm,bnep,btusb

One thing I would have to mention however, is that my motherboard does not contain a bluetooth module and I rather have to use a dongle to have Bluetooth connectivity, performing lsusb reports that it detects the dongle, and yet I have no bluetooth connectivity.

I'm informed that this requires a specific driver to be loaded, but I'm confused as to which one should I use.
I also want to note that scanning Wi-Fi connections with this device also does not work.

EDIT:
I got Wi-Fi scanning working downloading this driver: https://github.com/morrownr/88x2bu-20210702
However, Bluetooth still does not work, I'm going to try and install another set of drivers and see if those get the job done.

After looking at https://wiki.archlinux.org/title/Blueto … USB_dongle I found these results:

Running bluetoothctl then show shows this: 'No default controllers available', after running hciconfig -a hci0 it reported the following:

	Link policy: 
	Link mode: PERIPHERAL ACCEPT

After running sudo journalctl -f and unplugging then plugging in my dongle it reported the following:

After installing the package realtek-firmware from the AUR it started working correctly.
