Bluetooth problems are rare with the Raspberry Pi. But when they happen, it is most likely because the operating system is out of date or too old.
If you have Bluetooth issues with the Raspberry Pi, first try to re-write the micro-SD card with a copy of the Raspberry Pi OS. You can do this with a tool called Raspberry Pi Imager.
If you cannot get your Bluetooth to work, you can try searching the Raspberry Pi Forum for help. We do not know of any other issues with Bluetooth, but we hope that this helps.
