Hi all,
I am writing my first lwIP (1.3.2) project using an RTOS and I face an
issue.
My software connect my board to an TCP server and send TCP data using
netconn_write.
It's working fine (connection and write) during 10-20 seconds but after
data are not send at all and netconn_write return ERR_OK.
I also tried to disconnect the ethernet cable when this issue appears to
see if any error will be returned, but I still have netconn_write
returning ERR_OK.
I think I do something wrong, so I would like to have some help from you.
Please find the code of my software:
struct netconn *TxConn = NULL;
char ClientConnected = FALSE;
for( ;; )
{
while (ClientConnected == FALSE)
{
/* Create a new connection identifier. */
TxConn = netconn_new(NETCONN_TCP);
/* Try to connect with the TCP server */
if (netconn_connect(TxConn, &ipaddr_server, 10113) == ERR_OK)
ClientConnected = TRUE;
else
{
/* Close & Delete the Connection before trying again */
netconn_close(TxConn);
netconn_delete(TxConn);
}
}
/* Send data over TCP to server */
if ((netconn_write(TxConn, QueueTCPClientData.Data,
QueueTCPClientData.Size, NETCONN_NOCOPY)) == ERR_OK)
{
/* Always enter here even if Ethernet cable is disconnected */
}
else
{
/* Close & Delete the Connection before trying again */
netconn_close(TxConn);
netconn_delete(TxConn);
/* Set Flag to Flase to connect again */
ClientConnected = FALSE;
}
}
Thanks in advance for your help
Best Regards
Fabien
