the problem can be that i create 8 socket in different ports, an d only the thread can be use a one configuration TCP and not 8?

Thanks!

Hello i´m testing with this new advices.

I only want to accept the connection the first time, is for testing. the new code is this

portTASK_FUNCTION( vProtocolRTUServer, pvParameters )
{
    //Local variables of function ==> maybe put global
    int i,maxfd,ret;
    struct sockaddr_in sLocalAddr[NUM_SOCKET];

    //Create the NUM_SOCKET=8 connection to wait the accept
    for(i=0;i<NUM_SOCKET;i++)
    {

        //Create the 8 socket
        lSocket[i] = lwip_socket(AF_INET, SOCK_STREAM, 0);
        if (lSocket[i]<0)
        return;

        print_dbg(" Socket creado \n");

        //Bind to this socket
        memset((char *)&sLocalAddr[i], 0, sizeof(sLocalAddr[i]));
        sLocalAddr[i].sin_family = AF_INET;
        sLocalAddr[i].sin_len = sizeof(sLocalAddr[i]);
        sLocalAddr[i].sin_addr.s_addr = htonl(INADDR_ANY); //!!!!CUIDADO SINO VALE CUALQUIER DIRECCION CAMBIAR!!!!
        sLocalAddr[i].sin_port = PortConnection[i]; //Ports of the table

        if (lwip_bind(lSocket[i],(struct sockaddr *)&sLocalAddr[i], sizeof(sLocalAddr[i])) < 0)
         {
           //Error. Close the socket
           lwip_close(lSocket[i]);
         }

        //Listen to the 8 socket.Maximum 10 connection for socket
        if ( lwip_listen(lSocket[i],10) != 0 )
         {
           lwip_close(lSocket[i]);
         }
    }

    //Using of select function to wait for the accept connection
    FD_ZERO(&acceptset);
    print_dbg(" Sockets preprarados para entrar en el select \n");

    maxfd=0;

    //Add the 8 socket to wait the accept connection and then add the accept socket
      for(i=0;i<NUM_SOCKET;i++)
       {
        FD_SET(lSocket[i], &acceptset);
        if (lSocket[i]> maxfd)
         maxfd = lSocket[i];
       }

      while(1){
        // Check for received packets on configured sockets (blocking )
        ret = select(maxfd+1, &acceptset, NULL, NULL, NULL);

        if (ret > 0) //No error
            {
            //Analyze with socket receive

            for(i=0;i<NUM_SOCKET;i++)
            {
                //socket accept
                //First thing see the connection

                if (FD_ISSET(lSocket[i], &acceptset))

                   FD_CLR(lSocket[i], &acceptset);
                 }
            }
            }
      }

I send four thing the capture of this comunnication with customer, and two file of configuration.

In my program with emulator say me that i have connected only 6 socket, and the value os this is:
a) lsocket (create with function socket() ) values = 1,2,3,4,5,6,7,8
b) asocket(create with function accept() ) values = {1342769490, 154208563, 856240397, 172573772, 1158220114, 154143026, 808978738, 218780739}

the last value are bad no?

I don´t know what happend, i´m really lost, i don´t know what parameter change, and i don´t know if the code is OK.

Can you help me?
thank
