Re: [lwip-users] TCP write won't work after netconn_recv timeout

[Marco Jakobs]

Hi Kieran,

i'm using 1.3.0 with Free RTOS on an AT91SAM7X512.

My "basic idea" for the final solution is that LWIP should have incoming data in its buffers. With this, if i call

  tgtxcon->recv_timeout=1;    // Timeout setzen
  txbuf=netconn_recv(tgtxcon);    //Daten empfangen

every 20ms, it should "grap" data for my TCP connection out of its buffer to my "txbuf". Do you think this should work?

But first, the problem that "write" won't work after a timeout of the receive function must be solved ... ;-)

What version of lwIP are you using?  I have a vague recollection of a
bug in an earlier version that resulted in a timeout error being treated
as fatal.
