Is here where the error apperad, error en el conn, maybe always is the same
netconn_listen_with_backlog(struct netconn *conn, u8_t backlog)
{
struct api_msg msg;
/* This does no harm. If TCP_LISTEN_BACKLOG is off, backlog is unused. */
LWIP_UNUSED_ARG(backlog);
LWIP_ERROR("netconn_listen: invalid conn", (conn != NULL), return
ERR_ARG;);
msg.function = do_listen;
msg.msg.conn = conn;
#if TCP_LISTEN_BACKLOG
msg.msg.msg.lb.backlog = backlog;
#endif /* TCP_LISTEN_BACKLOG */
TCPIP_APIMSG(&msg);
return conn->err;
}
