Good job with this library!

I used this library to connect to iOS device from Android and it worked well! However when I am trying to connect to a Bluetooth 2.1+EDR audio receiver, it doesnt connect.

Below is the Logcat for the same -

I am not sure but does it have to do something with A2DP profile? We cannot stream audio with this?
