FreeRTOS+TCP is still in the lab
FreeRTOS+TCP is already used in commercial products and we encourage you to try it yourself. Be aware however that we are still refining its design, and the source code and documentation do not yet meet Real Time Engineers Ltd's strict quality standards.
Please use the forum for support, feedback and ideas, or contact us directly if you have a specific business interest.

Shutting Down and Closing a TCP Socket
Part of the FreeRTOS+TCP Networking Tutorial

A TCP socket that is not connected can be closed using the FreeRTOS_closesocket() API function.

A TCP socket that is connected should not be closed until the connection has been shut down. To gracefully shut down a socket first call FreeRTOS_shutdown(), then wait for read attempts on the socket to return FREERTOS_EINVAL, indicating that the socket is no longer connected.

The source code examples on both the Sending TCP Data and the Receiving TCP Data pages demonstrate a connected socket being shut down then closed.
