Problem to do the re connection in TCP-IP client

[Prof.Wagner]

Hi Everyone,

Some body knows how to recovery a connection if the device down by problem of power or some thing that is not possible to use the Net_Ethernet_28j60_disconnectTCP(SOCKET)? My device works just in client mode (PIC32) and if I disconnect it without the command Net_Ethernet_28j60_disconnectTCP(SOCKET) I didn't get to connect again in order to the server. My device send the SYN but the server disconnect it.
Thank you in advanced.
Best regards
Prof. Wagner

Hi,

The server has a keep alive parameter that is set with some reasonable value (60 seconds, for example);
When this period comes to an end, without and packet exchange, the server closes the socket.

In any case, the client must reconnect again, the question is will the server will let this on the same port.
If the port is not of interest, you could try reconnecting with some other ports, until you get connected.

Regards,
Filip.
