Re: [lwip-users] recieve timeout for tcp RAW api

[vincent cui]

Simon:

I add following a piece of code in loop. It also can make tcp timeout happen ..
#if LWIP_TCP
  /* TCP periodic process every 250 ms */
  if (localtime - TCPTimer >= TCP_TMR_INTERVAL)
  {
    TCPTimer =  localtime;
    tcp_tmr();
  }
#endif

I trace the tcp_tmr() function, it will remove tcp with TCP_WAIT status from 
list... 
Does it make sense ?

No, the socket code uses netconn timeout. In the raw API you have to implement 
this on your own by either using the poll callback (tcp) or implementing a 
timeout on your own (e.g. using sys_timeout).
