Hi, Does anyone knows how to pair bluetooth PINLESS device to Android Kitkat OS ? I bought an X431 idiag for Android but I can't pair my device because it's always pop up a message asking me to input passkey (PIN) to pair. As far as I know X431 doesn't have passkey (PIN), anything that I input as PIN gives me an error (0, 0000, 1234, _, etc) and leaving it blank, will disable OK button. I also tried with Bluetooth Auto Pair app with no success.
If anyone know how to do it, I will be very gratefull.
