L2CAP

Hello Dialog team

I am working on DA14682 DK and SDK1.0.14.1081. My questions are following:

1. How to transfer data (sensors data) over L2CAP to connected device (phone)?
2. Does it possible to transfer the data over L2CAP?
3. L2CAP is accessible from application layer?
4. Which APIs are used to transfer data over L2CAP?
5. Any example code available for L2CAP to transfer data?

以上提出的问题对我来说很重要understand in depth.

Thanks
Raj
