For my application I need to listen for connection on TCP port 80 and 81 (for example).
To realize this I can register two TCP server with
T+SCON=S,TSN,80,0 and T+SCON=S,TSN,81,0 .
WIzfi respond both with [OK].
If I connect to TCP server on port 81, then the connection is established on socket ref 0.
But unfortunately if I try to connect to TCP server on port 80, then connection is rejected.
Maybe Wizfi not support multiple TCP server?
Thanks for any advise, kzsolt2
