[lwip-users] Connection closes with Echoraw demo

[Francois Bouchard]

HI all,

 

 

The server side (embedded) runs the Echoraw demo, which implements a TCP Echo Server.  On the Client Side, my PC an Echo client runs and continuously sends packest, and measure the Round Trip Time.  Client sends Another message as soon as it receive the echo of the previous one.

 

That runs fine for a while, but after few time (mostly random I would say, although it can run for a few hours) the TCP connection terminates by itself !

 

I think server does'nt have the time to send ACK.  Should I pause client apps once in a while to let the server send acks?

 

Attached is the wireshark file when the TCP connection stops.

 

regards,
