[Furiantes]

Hello,

i have one more problem. My goal is:

- connect to server

loop
- send request (get request like 
/my_php?dataFrom=[something]&dataTo=[something])
- and wait for response
while(some termination)

I did this (code below), but a second request is never sent to server. 
First request id OK, i get the data in processes it ok. But at the 
second request, netconn_write it seems it never send it to a server 
anything (i watch with WireShark).

I tried to connect/disconnect, close - connect, but nothing worked.

So if please can anybody tell the correct procedure to send/recieve data 
TCP connection.

Thanks to anybody who will even read it.

Dan



resultCon = netconn_connect(xNetConn, &remote_ip, cdata->host_port_number );

    downloadBlock:
    xNetConn->recv_timeout = 30000;

    sprintf(request_my_c, "GET /my_php/data.php?startB=%d&lenB=%d

transData,transDataLen,cdata->host_add[0],cdata->host_add[1],cdata->host_add[2],cdata->host_add[3] 
, cdata->host_port_number);


netconn_write(xNetConn, request_my_c, strlen(request_my_c), NETCONN_COPY);

    while (1)
    {

        resultRecv = netconn_recv(xNetConn, &buf);

        //process data
       //all blocks downloaded -> break
        //goto another block;

}

some code....
