[lwip-users] netconn_x API, Creating a TCP client fails

[Sägesser Walter]

I have succeeded in setting up a server application using either the Raw API or the netconn_x API. But I also need a TCP client on the device, able to send state information to a server app on a PC.

I have

struct netconn * xNetConn = netconn_new ( NETCONN_TCP );  xAddr.addr = M_IpAddrEncode ( 192, 168, 142, 52 );

// xNetConn->recv_timeout = 100;

Int32 xRes = netconn_bind ( xNetConn, &xAddr, 9000 );

while ( true )

{

RTOS_TaskSleep ( cT1s );

xRes = netconn_connect ( xNetConn, &xAddr, 9000 );

if ( xRes == ERR_OK )

netconn_write ( xNetConn, "Ein Comm String", 16, NETCONN_NOCOPY );

}

} // procedure ExTaskEthClient

 

 

Freundliche Grüsse / Kind regards

Walter Sägesser
