The easiest one to install was Fedora Workstation 33.
Update your OS from "Software"
Type this in your terminal
dmesg | grep -i 'blue'
You might find a line saying
[5.763779] bluetooth hci0: Direct firmware load for brcm/BCM4343A0.hcd failed with error -2
[5.763789] Bluetooth: hci0: BCM: Patch brcm/BCM4343A0.hcd not found
Or something similar. Download BCM4343A0.hcd from this repo and go to Downloads (or where it downloads) and open up a terminal there and type
sudo cp BCM43430A0.hcd /lib/firmware/brcm/
Do a reboot and it should work! In case it doesn't, rename the file to whatever it's asking for (as long as your bluetooth is based on BCM43430A0)
