Using Bluetooth HID requires additional configuration of the operating system. For v2+, this means losing the UART port, since it will be used by Bluetooth. Also, Bluetooth operation was tested only on RPi4 and v2+ platform. Other boards may require different system service settings. Making the required changes for BT to work will also disable normal KB/MOUSE functionality therefor this will need to be disabled before normal operation can occur.
Bluetooth mouse can work only in [relative mode](mouse.md). The reason is that many Bluetooth host drivers do not correctly implement HID descriptors. Horizontal scrolling is not supported for the same reason.
* If something went wrong, use the web menu `System -> Reset keyboard & mouse`. This will cause unpair the device and switch the PiKVM to public mode before the first client is connected.
