Check the result for this:

sudo dmesg |grep -i bluetooth

My case was identical to yours, and I was giving this error in the result:

[    3.935429] Bluetooth: Patch file not found ar3k/AthrBT_0x11020000.dfu

And the solution was to follow zxcde's answer to Patch file not found ar3k/AthrBT_0x31010000.dfu:

You can try my solution:

  1. Download linux-firmware_1.201.tar.xz from http://archive.ubuntu.com/ubuntu/pool/main/l/linux-firmware/linux-firmware_1.201.tar.xz (you can visit https://packages.ubuntu.com/impish/linux-firmware for more details).
  2. Extract linux-firmware_1.201.tar.xz and copy the ar3k folder into /lib/firmware.
  3. Restart your computer.
