My RPi3 installation has lost its onboard Bluetooth lately. I have changed literally nothing except installed recent upgrades (now core 2023.12.1, supervisor 2023.11.6, OS 11.2). I believe this happened with the OS upgrade.
I tried removing the Bluetooth integration, but it refuses to reinstall (“no adapters found”). Config/hardware doesn’t show anything starting with “hci” (not sure if it even should). Where do I go from here?
