Hi all,
I have LWIP_TCP_KEEPALIVE enabled, and I am using lwip_send(clientfd,
databuffer, datacount, 0) to send out data
At 200kb/s and full-size packet, lwip_send will failed once a while
At this point, how can I tell if the failure is from broken line
(keep alive failed) or out of tx buffer? if it is out of tx buffer,
anyway to get the warning first so that I can send out a smaller packet first?
Thanks!
