How to programmatically pair a bluetooth device on Android

Question

For my application I\'m trying to programmatically pair a bluetooth device. I\'m able to show the pairing dialog for the device I want to pair and I can enter a pincode. Whe

Answer 1

I've found that using different values for PAIRING_VARIANT_PIN result in different pairing UI behaviours.

See this page: http://code.google.com/p/backport-android-bluetooth/source/browse/trunk/backport-android-bluetooth201/src/backport/android/bluetooth/BluetoothDevice.java?spec=svn67&r=67

I suspect the problem you're having is that both devices are Bluetooth 2.1, in which case a pairing request should result in a 6 digit passkey being displayed on both devices.

The best result I was able to achieve was using PAIRING_VARIANT_PIN = 0. When prompted by my application, I entered pin 1234 and a 6 digit passkey appeared on my target device. The pairing UI finished and that was that.

Either you need to find out how to initiate a Bluetooth 2.1 pairing request, using some other pairing variant or pairing variant pin. Or, you're not catching the result of the activity that's running properly.

Given the amount of time I've been trying to do this, I've decided that my end users will just have to pair using the android settings before using my application.
