Trying to pair a bluetooth device (Kindle tablet) to my desktop PC. Bluetooth turned on in both devices. Tablet show my computer's name and provides a passkey that Windows 10 must use. When I go to Devices and Printers, Bluetooth...Windows will search for devices, list an unknown one, but I see nowhere to give it the passkey to use. I tried Add Device, but it only searches. Does not ask for passkey. Where do I enter passkey information for a bluetooth device into Windows 10?
