[lwip-users] netconn_recv partial data

[N.Karakotas]

Hello,

 

Im trying to receive an image from an IP camera but im having a problem receiving data. I successfully connect and access the camera and I then try to get the data.

I receive the header response such as:

 

HTTP/1.0 200 OK

Date: Fri, 20 Jan 2012 21:50:41 GMT

Server: Mbedthis-Appweb/2.4.2

Content-type: image/jpeg

Last-modified: Fri, 20 Jan 2012 21:50:41 GMT

ETag: "32c-3142-58078"

Content-length: 208451

Connection: keep-alive

Keep-Alive: timeout=10, max=1000

 

\323?\374\360

 

All I receive is 256 bytes of data and once the loop executes again it has no data. Below is the code:

 

inbuf = netbuf_new ();

    err_t resp = OpenHTTPSocket(conn,netif_eth0,method,url,header,auth);

 

    /* Get the response */

    if(resp == ERR_OK){

        memset(httpBuf,0,BUF_SIZE);

 

        while((resp = netconn_recv(conn,&inbuf) ) == ERR_OK){

            netbuf_first(inbuf);

            do{

                netbuf_data(inbuf, (void*)&data, &buflen);

                printf("%s\r\n",data);

            }while(netbuf_next(inbuf) >= 0);

 

        }

 

        printf("%d\r\n",resp);

 

    }

 

    netbuf_delete(inbuf);

    netconn_close(conn);

    return ERR_OK;

 

 

#define PBUF_POOL_SIZE          8

#define PBUF_POOL_BUFSIZE       512

 

 

Does anyone know why this is happing? Any place to look? lwip versio 1.4.0

 

Regards,

Nick
