With the help of @Jtyle6 and his pi zero 2 we have bluetooth working on this device. It is a BCM43430B0 and the kernel was looking for BCM.hcd firmware to load. So I made a temporary link “ln -s BCM43430B0.hcd BCM.hcd” in the firmware-raspberrypi package for now in /usr/lib/firmware/updates/brcm/.
The new firmware package has been pushed to all branches when the mirrors sync.
firmware-raspberrypi 7.1-1
To have bluetooth on the pi zero 2:
sudo systemctl disable attach-bluetooth.service
# Add this to config.txt:
dtparam=krnbt=on
Then reboot
