Hi Ramazan:

The device can act as both server and client. Because they running on different sockets.

I would suggest you start with the demo lwip_httpsrv. Then add your tcp echo client code.

Please refer to lwip_httpsrv_freertos.c

/*!
* @brief The main function containing server thread.
*/
static void main_thread(void *arg)
{
LWIP_UNUSED_ARG(arg);

stack_init();
http_server_socket_init();

vTaskDelete(NULL);
}

stack_init initialized the lwip stack;

http_server_socket_init initialized the web server.

Then you can add your echo client function ( for example, tcpecho_client_init) from there.
