Which Bluetooth devices have you tried to pair / connect with your N2?
Just in the case this is a misunderstanding about how the Bluetooth Settings work in CoreELEC. The Bluetooth section of the CoreELEC settings won’t show the USB Bluetooth adapter itself, but should show any Bluetooth devices that are currently discoverable or have been paired / trusted in the past.
