Re: [lwip-users] TCP Receive Timeout

[Yacob Hassidim]

Hello,

Thanks Simon,

Do you mean I must to enable LWIP_TCPIP_TIMEOUT and LWIP_SO_RCVTIMEO to enable 
TCP receive timeout?

Can you please answer to the next question also?

The timeout value shall be set by the function netconn_set_recvtimeout().
Can I use netconn_set_recvtimeout() at any time or it must be at system startup?

Have you found out by now that LWIP_TCPIP_TIMEOUT has nothing to do with 
receive timeouts?

When using sockets, just try to use standard calls and come back here for 
anything that doesn't work compared to Unix/Linux/windows.
