I added
pxSRVconn = netconn_new(NETCONN_TCP); // init conn
if (pxSRVconn != NULL)
if (pxSRVconn->pcb.tcp != NULL)
pxSRVconn->pcb.tcp->so_options |= SO_KEEPALIVE; // turn on
keep-alive
and not keep-alive is working. But I don't understand why when I close
socket on my windows serwer the lwIP does not notify that. Only when I close
my serwer the lwIP close too (RST state?).
cheers
