Dear sir,

    I recently use your company's lwip on ARM cpu. But now I have a problem when I do the Client and need you give me a help! Follow is my code:

void T_LwIPClientEntry(void * pvArg)
  {

      extern void vHandler_Client(ST_NETCONN *pstConn);
      ST_NETCONN  *__pstConn;  
      struct ip_addr __stRemoteIpAddr;    

      INT8S  __s8ConnClient;
      INT8U  i=1;
    
while(OS_TRUE)
{     
  IP4_ADDR(&__stRemoteIpAddr,Remote_IP_ADDR_0,Remote_IP_ADDR_1,Remote_IP_ADDR_2,Remote_IP_ADDR_3);       
       __pstConn = netconn_new(NETCONN_TCP);
       netconn_bind(__pstConn, NULL, 40000); 
       __s8ConnClient = netconn_connect(__pstConn,&__stRemoteIpAddr,60000);
       if(__s8ConnClient != -1)   //if(1)
       { 

          vHandler_Client(__pstConn);                                 

          while(netconn_delete(__pstConn) != ERR_OK)
             OSTimeDlyHMSM(0, 0, 1, 0);
       
    }//end //if(1)
 }//end while
}//end T_LwIPClientEntry

    The Server is PC. The problem is that when the Client runs before the Server

for a while, the  connection will be failure . But when the Server runs before the Client for a while, the  connection will be successful .

    Thank you very much!

                                                       Good Luck,

                                                       Mrs Gao
