Common for all mainboards with BT:
The Bluetooth in the BIOS just initializes the hardware but has no protocol stack for it. Bluetooth requires drivers and utilities to manage the connection, neither of which are available in the BIOS.

If you want to use your BT keyboard in the bios, you cannot use the onboard BT.
If you find a "Bluetooth USB Dongle" that is able to provide USB HID support (aka "HID Proxy"), then you may be in luck, otherwise, I'd suggest it's not possible.

HID Proxy mode works by running a minimal Bluetooth stack on the dongle - it then enumerates as a USB "Human Input Device" instead of a "Bluetooth Radio"... this minimal stack is able to communicate with a paired keyboard / mouse, and interpret their input such that as far as the PC knows, a basic wired USB input device is connected.

I have a X570 Taichi motherboard and a Surface Ergonomic Bluetooth keyboard.

Since the motherboard has onboard Bluetooth, I thought the keyboard could be used in UEFI too, but it doesn't seem to be working until Windows is loaded.

Is there any way to make it work? I have HDD passwords set in BIOS so I have to enter them on each boot, and the only way for it now is to have a separate corded keyboard, this is very inconvenient.]]> Sun, 27 Oct 2019 19:51:42 +0000 https://forum.asrock.com/forum_posts.asp?TID=12753&PID=69380&title=using-a-bluetooth-keyboard-in-uefi-x570-taichi#69380
