The last couple of weeks i was working on a c++ wrapper for the networking part of the SDK.
Here it is:
https://github.com/i-n-g-o/esp-socket
It is a wrapper around the SDKs networking structures and is an alternative to the lwip socket implementation coming along with the Arduino package. It uses the espconn structures and callbacks provided by the SDK.
I am sure it can be improved and would be interested in comments and suggestions in design, code and usability.
