Hi,
I am using netcon api in simple application. Device is a server
processing connections in loop, PC is a client. After PC establishes
connection we go into simple loop:
while (err == ERR_OK) {
if (streaming_enabled()) {
err = netconn_write(pc,sbuf, 1152, NETCONN_COPY);
}
vTaskDelay(1);
}
where pc is struct netconn *.
However if streaming is disabled, there is now way we can detect that
PC sent FIN and closed connection - so subsequent connection to same
port to server causes RST (we are still in inner loop so we cannot
accept next connection).
What can i do to detect that PC closed connection? I do not mean
Ethernet layer error and other "hard do diagnose in few miliseconds"
problems, rather typical situation with connection closed by PC.
Regards,
Krzysztof Wesołowski,
