There is this file /lib/firmware/ar3k

$ du -h /lib/firmware/ar3k

36K    /lib/firmware/ar3k

There is no ar3k directory in Ubuntu 22.04 directory. I try to create this directory, and then execute sudo cp linux-firmware/ar3k/AthrBT_0x11020000.dfu /lib/firmware/ar3k. after restart, dmesg reports that a new file is missing：Patch file not found ar3k/ramps_0x11020000_40.dfu, and then I go to Google to find a copy. After restart, the error becomes like this

sudo dmesg |grep -i blue

I download file at :https://github.com/cernekee/linux-firmware/blob/master/ar3k/ramps_0x11020000_40.dfu

Hello! You need to add a lot more info about what you're trying to do when adding Bluetooth devices, and what error messages you get. — Artur Meinild, Apr 21 '22 at 08:15
It's reported as a bug - please expand on the bug reports: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1967935 — Artur Meinild, Apr 21 '22 at 08:21
You need to find the firmware file AthrBT_0x11020000.dfu. It is possible to extract it from a Windows driver. — Pilot6, Apr 23 '22 at 16:19
It has been already added to linux-firmware. See my answer. — Pilot6, Apr 23 '22 at 16:27
I had similar initial fun with ubuntu 22.04 mate on aus pn51 but solved by just doing apt install linux-firmware — lxx, Apr 24 '22 at 03:20

The firmware for your Bluetooth hardware isn't installed. You can install it this way. Run in a terminal:

sudo apt install git
git clone git://git.kernel.org/pub/scm/linux/kernel/git/firmware/linux-firmware.git
sudo cp linux-firmware/ar3k/AthrBT_0x11020000.dfu /lib/firmware/ar3k
sudo modprobe -r btusb
sudo modprobe btusb

Your Bluetooth should be working.

May need to do sudo systemctl enable bluetooth.service && sudo systemctl start bluetooth.service after – lxx Apr 24 '22 at 03:22
thank you Pilot6,After I install your steps, dmesg still displays the same error as before after restarting – hao wu Apr 24 '22 at 05:05

I have the same issue, tried to make what Pilot6 said but didn`t work. I have installed bluez and blueman tools. In ubuntu 20.04, this solved the same problem. But now, this happen. – Gabriel Bueno Apr 23 '22 at 23:33
Please don't add information in comments, [edit] your question. Please add output of ls /lib/firmware/ar3k – Pilot6 Apr 24 '22 at 11:02
Please edit YOUR question, not my answer. You should have /lib/firmware/ar3k directory. If not run sudo apt install --reinstall linux-firmware. If there is an error with another file, then copy this file too the same way. – Pilot6 Apr 25 '22 at 05:10
thank you Pilot6,My Bluetooth device is already working – hao wu Apr 25 '22 at 13:44

I too HAD this problem. Then I tested 22.10 and had the same problem. Turns out starting with 22.04, Blueman added a new "feature" called "Hide unnamed devices" in the View pull-down menu. The real problem is that feature defaults to enabled. Guess what? EVERY BT device is unknown, UNTIL IT'S NOT! So they're all hidden. Not smart.

Just uncheck this box, put your BT device in pairing mode, click Search, and enjoy Bluetooth again!
