[lwip-users] TCP Echo (sockets) only accepting connection once |

Hello everyone,
I've got lwip basically working (UDP Send, ping, DHCP, etc) under FreeRTOS
on my hardware, but I'm having a heck of a time getting a simple TCP Echo
server to work as expected.
I've separated the listener thread from the worker threads so that more than
one client can connect, but no matter what I do, only the very first
connection is successful. No other client can connect after the first one
does, and not even the first client can disconnect and then re-connect.
I'm guessing that I'm missing something very simple, but I sure as heck
can't see the forest through the trees here.
If anyone sees anything obvious, please say so.
Thanks,
Ben
