Im trying to set up

passkeys should be entered for both devices.
like when you are trying to paired your phone with you friend's
it would then asked to type in a passkey, you can type in any passkey you like but it should be same combination with your friend's. (so you can use 1234 punch in on yours and your friends need to use 1234 code punch in his phone, so both bluetooth device will be paired successfully).
