Hi
I am using LwIp Rev 1.4.1, on an an embeded system, and trying to open a TCP
session against Jpref TCP test tool, running on PC, and the session is not
opened.
*The source code on my system, for opening the TCP session:*
#define TCP_TEST_PORT ( 5001 )
struct netconn *TcpTestListener, *pxNewConnection;
uint status = 0;
struct netbuf *pxRxBuffer;
char *pcRxString;
unsigned short usLength;
/* Create a new tcp connection handle */
TcpTestListener = netconn_new( NETCONN_TCP );
ZR_ASSERT(TcpTestListener != NULL);
status = netconn_bind(TcpTestListener, IP_ADDR_ANY, TCP_TEST_PORT );
ZR_ASSERT(status == TX_SUCCESS);
status = netconn_listen( TcpTestListener );
ZR_ASSERT(status == TX_SUCCESS);
/* Loop forever */
for( ;; )
{
/* Wait for connection. */
status = netconn_accept(TcpTestListener, &pxNewConnection);
ZR_ASSERT(status == TX_SUCCESS);
if((status == TX_SUCCESS) && (pxNewConnection != NULL))
{
/* Service connection. */
/* We expect to immediately get data. */
status = netconn_recv( pxNewConnection, &pxRxBuffer );
ZR_ASSERT(status == TX_SUCCESS);
if( pxRxBuffer != NULL )
{
/* Where is the data? */
status = netbuf_data( pxRxBuffer, (void **)&pcRxString,
&usLength );
ZR_ASSERT(status == TX_SUCCESS);
/* Write back the data */
status = netconn_write(pxNewConnection, pcRxString,
(u16_t)usLength,
NETCONN_COPY );
ZR_ASSERT(status == TX_SUCCESS);
netbuf_delete( pxRxBuffer );
}
status = netconn_close( pxNewConnection );
ZR_ASSERT(status == TX_SUCCESS);
while( netconn_delete( pxNewConnection ) != ERR_OK )
{
tx_thread_sleep(20000);
}
}
}
Do you about a problem when working against the Jpref tool, or you see a
problem in my code ?
Thanks
Avi
