Bluetooth does not work on Raspberry Pi Zero 2W

[henrik242]

I have a Raspberry Pi Zero 2W with VenusOS firmware 3.21. Bluetooth doesn't work, and /var/log/messages is spammed with Bluetooth related error messages even when Bluetooth is disabled in the Remote Console. It amounts to 100K every 10 minutes, which means that I don't have more than about 1 hour of history:

$ ls -ltr /var/log/messages*
-rw-r--r--    1 root     root        102492 Jan 16 07:43 /var/log/messages.5

-rw-r--r--    1 root     root           642 Jan 16 08:32 /var/log/messages

Here are the messages that are repeated every 10 seconds:

If I add a symlink the log spamming stops (Bluetooth still doesn't work):

cd /lib/firmware/brcm
ln -s BCM43430B0.hcd BCM.hcd

Bluetooth doesn't work when I enable it in the Remote Console, and I get this every second in /var/log/messages:

rfkill: unblock set for type bluetooth

I got a little nudge from the Raspberry Pi forum, and I have gotten things to work! The bluetooth entry in the VenusOS wiki says this:

modprobe -v btusb
echo "0b05 17cb" >> /sys/bus/usb/drivers/btusb/new_id

I added it to /data/rc.local and rebooted. All the log file spam is gone!

Thanks! I’ll leave this open; sounds like something we can easily fix in Venus OS to make it work out of the box.
