Thank you for you enquery and patience. The bluetooth devices normally don’t work if the don’t have some type of OS running, which will allow the pair of the two devices (PC and device). But if you are using a keyboard/mouse with it own doungle, this might work. This is because the devices will pair with the USB doungle. But again this can be a 50/50 chance. The best option will be to use a USB Keyboard/Mouse.
Any other questions please feel free to ask.
