[lwip-users] Re transmission behaviour?

[Fred39]

Hi Lwip Users

i am facing a problem and cant find a solution. I have a master slave
application which uses tcp protocol. I get a request and reponse to it. If i
put the master cylce time very fast (send request every 1 ms)the
transmission looks ok
 request -> 
 <- response 
 request -> 
 <- response 
 request -> 
 <- response 
 request -> 
 <- response 
But if i set the cycle time of the master slow, like 80ms and slower i get
an response and a retransmission of that response for every request.
 request -> 
 <- response 
 <- retransmission
 request -> 
 <- response 
 <- retransmission
 request -> 
 <- response 
 <- retransmission

Does this problem sound familiar to you? I have to say that my lwip version
is 1.1.1 and i cant change it to a new one.

I checked the timer because i thought the problem is there but no success.
I cant say that the lwip stack is to slow because when the cycletime is fast
it works, very weird behaviour.
Any suggestions?


Regards 
Fred
