Bluetooth Pairing one device on Dual Boot of Windows & Linux - Stop having to Pair Devices

test You may have experienced when dual booting that you need to re-pair your bluetooth devices (ie., Headphones, mouse, keyboard, etc) this usually happens because you have already paired the device with another operating system using the same bluetooth adapter when dual booting (either Linux or Windows).

Some devices cannot handle multiple pairings associated with the same MAC address (ie., bluetooth adapter). As per suggested on the ArchWiki you can fix this by re-pairing the device each time, but there's actually another solution to not do so each time you choose to use your device on a different OS.

How can we accomplish this?

Easy, just pair the device on a OS and copy the bluetooth keys generated to the other OS so our device doesn't notice the difference.
