I want to use the netconn_api for my app , but I have a question :
I need to optimize the bandwith due to high latency connection
(intercontinental) , so I'll send big packets
(about 5KB by 5KB) .
That doesn't result in big packets: the data will be splitted into
multiple packets of 1460 bytes of data.
Because the systeme doe not havo much memory I would
send the data with NETCONN_NOCOPY .
So I have to be sure the full packet was ACK to be able to use the netbuf
again .
How can I know if the full packet was ACKed byt the remote peer ?
With the netconn api, I think there's no way to tell. With the raw api,
your sent-callback would be called with the amount of bytes acked by the
peer, but the raw api is a little harder to use than the netconn api.
