How to connect to bluetooth headset using A2dp profile programmatically?

Question

Android

Hello, I am writing an application on xamarin, the question arose, how can I programmatically connect a headset using the A2dp profile, do not offer a program like BluetoothChat, I already tried to look there, but it provides a connection only for messaging (the device is not detected as a headset and no sound is transmitted to it ).
If someone has ideas or tips, otherwise I tried everything that is possible, nothing rolls, then I know that this is possible (maybe not in xamarin, but on android for sure) I know. with the help of https://play.google.com/store/apps/details?id=org.... this program I was able to connect programmatically
