I can't enable bluetooth

I use GNOME in arch. When I try to enable bluetooth via GNOME's settings, I face this:

GNOME's version is 44.5.
I have installed gnome-bluetooth and gnome-bluetooth-3.0.
Why this is happening?

Re: I can't enable bluetooth

It's possible that missing firmware or kernel incompatibility could be the causes. I'll provide steps to check for missing firmware, kernel compatibility, and how to download and copy Bluetooth firmware.

- Check dmesg for Firmware Errors:
RezaHoss you can open a terminal and run the following command:

dmesg | grep -i firmware

This will show any firmware-related errors in the system logs.

- Check Kernel Version:
Ensuring that the kernel version is compatible with the GNOME and Bluetooth versions is crucial. You can check the kernel version with the following command:

uname -r

Also, the kernel version shall be compatible with your Arch Linux version.

Downloading and Copying Bluetooth Firmware:
If the firmware is indeed missing, it can be obtained from the Linux firmware repository. Here are the steps:

- Clone the Linux firmware repository:

git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git

- Copy the required Bluetooth firmware to the /lib/firmware/ directory. For example, if the missing firmware file is brcm/BCM20702A1-0a5c-21e8.hcd, then:

sudo cp linux-firmware/brcm/BCM20702A1-0a5c-21e8.hcd /lib/firmware/brcm/

(I'd cp * to the /lib/firmware/ without forcing or replacing anything so I wouldn't mess with the working firmwares)

- Reboot the system:

sudo reboot

- Check Bluetooth Service Status:
It might also be beneficial to check the status of the Bluetooth service using the following command:

systemctl status bluetooth

If the service is inactive, it can be started with:

sudo systemctl start bluetooth

These steps should aid in diagnosing and fixing the Bluetooth issue on GNOME in Arch Linux.
