Home Assistant on Home Assitant OS running on a Raspberry Pi 4.
I am constantly getting this message, like every day. I can power the device down, power it on again, and it will go away for a little bit, but it always comes back by the end of the day.
Is it possible for me to just disable the Bluetooth on my Pi as I don't even use it?
Or is this a symptom of something else?
Bluetooth adapter requires system power cycle
Warning · Reported by Bluetooth
The Bluetooth adapter hci0 (DC:A6:32:A1:73:6F) (bcm43438-bt) is stuck in passive scanning mode despite requesting active scanning mode. Automatic recovery was attempted but failed. This is likely a kernel, firmware, or operating system issue, and the system requires a complete power cycle to recover the adapter.
In passive mode, the adapter can only receive advertisements but cannot request additional data from devices, which will affect device discovery and functionality.
Manual intervention required:
Shut down the system completely (not just a reboot)
Remove power (unplug or turn off at the switch)
Wait 10 seconds
Restore power and boot the system
If the issue persists after power cycling:
Check for kernel/firmware updates
The onboard Bluetooth adapter may have hardware issues
