Using Java reflection, I've found that the BluetoothDevice class exposes the following method: public boolean getRemoteServiceChannel(java.lang.String,short,android.bluetooth.IBluetoothDeviceCallback) to get asynchronously the RFCOMM assigned to a certain service. To get the response, I had to find the definition of IBluetoothDeviceCallback. Therefore, I had a look to the Android's source code to (hopefully!) find what I needed; finally I used the AIDL definition of BluetoothDeviceCallback to generate the IBluetoothDeviceCallback in my library source tree. Much more critical was to find the reference to BluetoothSocket; in fact, it was org.bluez.RfcommSocket on early SDK release and android.bluetooth.BluetoothSocket on latest source repository. None of them was available using reflection. Finally, checking some possible name, I've found the current firmware use old class name with new package name (that is: android.bluetooth.RfcommSocket). > 3 Did you ever notice and consider merge all the function provided > here: > > http://groups.google.com/group/android-platform/browse_thread/thread/0395e2de5702b364/ed50c9670218f666?#ed50c9670218f666 > > Or you have noticed this? I didn't read this post, thank you for hint. Since I was not aware of that discussion, I've written my (simple) API from scratch, trying to keep them very simple. Do you think it would be better to align the library to that proposals?

Do you know if there is any trial/demo of it?
