Hi Anson,
lwIP does not do a lot of buffering like your
average full blown TCP/IP stack does.
You may want to try ARP queueing in the etherarp.c
implementation. It should
do the job.
Configure this in lwipopts.h
Let us know the results, thanks!
Leon.

Subject: [lwip-members] UDP problem
Dear All,
I have a question about sending
UDP packet. I wanna send some UDP packets to PC. I send the first
UDP packet by the BSD socket API. Because lwip doesn't know the PC MAC
address, it will send the ARP packet to request the MAC address of PC. But it
doesn't send the first packet to PC and return to me. Is it a bug of
lwip? Thanks!
