Hello Peter,
you're right: what a mess with this part.
See below at you're remarks.

Hi Andreas,
first: don't know if Bluetooth has worked before. If updated today the laptop
and noticed Bluetooth isn't working.
Nope, the bliuetooth for the brcmfmac parts is complicated.
dmesg | grep -i bluetooth missed 'brcm/BCM4345C5.hcd
After searching Internet I've
foundhttps://copr.fedorainfracloud.org/coprs/jwillikers/pinebook-pro and
installed ap6256-firmware-2020.02-10.fc39.aarch64.rpm
Well per the rules for copr that shouldn't be there, but that aside....
There's two different WiFi parts, both using brcmfmac, in the Pinebook
Pro so it will depend on which one you have.
One of those parts is a Cypress part, now part of Infineon, and the
WiFi for that part will work OOTB. The WiFi for the synaptics part
won't work OOTB. That should tell you what variant of the HW you have.
You then need to go and find the right version of the BT firmware for
the one you have because neither of those firmware are upstream.
The most useful bit of debug is actually from the wifi module:
# dmesg | grep FWID
[ 20.285673] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4356/2
wl0: Apr 9 2021 00:40:07 version 7.35.349.104 (775a9ab CY) FWID
01-64b609e0
What I have:
[ 37.944145] brcmfmac: brcmf_c_preinit_dcmds: Firmware: BCM4345/9 wl0:
Jun 16 2017 12:38:26 version 7.45.96.2 (66c4e21@sh-git) (r) FWID01-1813af84
BTW: for the WIFI-Part I've installed
https://fedora.roving-it.com/brcm-pinebookpro-0.0-1.noarch.rpm from your
nullrOute BLOG.
<https://nullr0ute.com/>
The two letter right before the FWID tells you who makes the module.
The above is from the Rock960 which has a Cypress part.
Basically Broadcom made the original HW, they then sold it to
Cypress... but kept rights to it.... then Broadcom sold it to
Synaptics.... but kept the rights to it. So there's 3 vendors making
similar but not the same HW, in all cases the BT firmware can only be
described as a mess!
Any hint where I can the correct firmware ?
Peter
