General :: Bluetooth Stack AIDL Reflection Methods?

I work at a small company that fields autonomous android devices which programmatically connect to bluetooth telemetry devices. These devices require pins, so we need to automatically create a pairing in order to connect to the bluetooth devices. We DO have root access.

Since the new Bluetooth Stack in Android 4.2, I have been unable to use this common AIDL bluetooth reflection method in our private utility app:

Code:
public IBluetooth getIBluetooth() {
IBluetooth ibt = null;
try {
Class c2 = Class.forName("android.os.ServiceManager");
Method m2 = c2.getDeclaredMethod("getService",String.class);
IBinder b = (IBinder) m2.invoke(null, "bluetooth");

[code]...

The issue about this strategy no longer working is documented here. I previously used the setPin method as well as the createBond method from this Interface, and now I cannot.

Is there anyway to manually create a bluetooth pair profile under Android 4.2? Is there a database file where the profiles are stored that we can use root and sqlite3 to access?
