|Subject:||[lwip-users] lwipopts.h, how to enlarge send and receive packet size|
|Date:||Fri, 12 Jul 2013 09:42:59 +0900|
I am new one in this group.
Very glad to know your all.
I use Stellaris and I use the open source (from TI homepage) for driver.
Sometimes, my stellaris need to send or receive large size packet (almost 1200byte).
However, the buffer size is defined as
#define PBUF_POOL_BUFSIZE 256
Now, my stellaris can send packet as large as 1200 byte but it can NOT receive packet (1200bytes).
and I do not know the reason.
I have 1 question.
When I send a packet (1200 bytes), and the "#define PBUF_POOL_BUFSIZE 256",
the first 256 packets are saved in the buffer and
the rest 1200-256 bytes overflow the buffer size and not correctly saved.
Is my comprehension above correct?
Is it possible to configure the PBUF_POOL_BUFSIZE and PBUF_POOL_SIZE to send and receive packet as large as 1200 bytes.
Thanks in advance and sorry for interruption.
