Question

Did u set the permissions in the manifest?

<uses-permission android:name="android.permission.BLUETOOTH_ADMIN"/>
<uses-permission android:name="android.permission.BLUETOOTH"/>

And whats exactly your exception?

EDIT: according to this http://developer.android.com/reference/android/bluetooth/BluetoothDevice.html#ACTION_ACL_DISCONNECTED it's a low level exception that shouldnt occur.

How to programmatically tell if a Bluetooth device is connected? (Android 2.2) Does this help you?
