I am using lwip_send to send out the data. I will try to find out more about stat_display
> 1) I am using TCP API. That isn't quite what I meant. To send data do you call tcp_write() or netconn_write() or send() for example? If you use tcp_write() directly then MEMP_NUM_NETBUF will have no effect and is not your problem. If you call the function to display that stats and it shows nothing then something is wrong: it should print statistics about the resources used. You'll have to debug what's gone wrong. Kieran
