Hello,
first: don't know if Bluetooth has worked before. If updated today the laptop and noticed Bluetooth isn't working.
dmesg | grep -i bluetooth missed 'brcm/BCM4345C5.hcd
After searching Internet I've found https://copr.fedorainfracloud.org/coprs/jwillikers/pinebook-pro and installed ap6256-firmware-2020.02-10.fc39.aarch64.rpm
No failure on
