Direct Access to SCO Audio Streams

[lohchab]

Hello, I am struggling to find a solution to access the Raw Audio Packets either in some other codecs or PCM format with the help of 32feet .NET Library I am able to dial/receive the calls via my Android Phone. But needs a way to access the Audio Stream so I can directly play some recorded sound files back to the caller automatically on call answer. But Windows 10 Bluetooth Drivers handle the SCO Connection within the driver. It will be great if you can help in getting the access to the Audio Packets/Stream someway either by the Default Microsoft Bluetooth Driver or some other custom simple driver giving SCO Connection access to the User-Space Application.

The APIs you used in your program can be only used for the Call Control.

You can't do that with the default Microsoft driver. You need to install third-party drivers or write a custom profile driver (user-mode).
