Hi,
My embedded system (ES) starts a TCP Listener socket that waits for a client connection. My client is a VB NET app that connects to TCP listener and polls the unit @ 200 msec interval. It seems after some time, which varies, my client socket times out waiting for response from ES. The problem seems to be in the TCP library (EDK) and was confirmed by SiLabs.

1) Has anyone developed a Listener socket on F120 that works? If so would you share code snips?

2) Although multiple connections is not easy due to memory limitation, I wrote a test firmware that allows 2 connections; Upon timeout on existing remote connection, the client opens 2nd connection; In ES, the 2nd connection attempts to close the broken connection; However this does not work since the TCP stack reports that 1st connection is still active after I have close it and I can not reuse it again. Has anyone tried this scenario ?

Thanx in advance.
