Hi,
First of all forgive me if I'm asking something so fundamental but I
can't find any remedy to my problem. Besides, I have no idea what's
going on.
I'm running lwIP on my custom Arm7 board successfully for a while. Until
now I used UDP(it's working quite well), but I want to implement TCP
functionlity as well. I write my TCP code
(actually I'm using one of the examples presented in this list before)
using raw api. I can successfully send large packets ( ~ 1k) but small
packets(~ 30 bytes) are merged into one packet.
For example, When I send "Read" and "Write" messages, they're delivered
as "ReadWrite".
I'm not sure that this is fault of lwIP stack! Because I see the same
behaviour when I send messages from my linux box also. I don't know what
kind of an error I'm making can cause this
kind of strange behaviour.
Should I play with my lwIP options or should I review my linux network
programming knowledge? Moreover, can I investigate this problem using
Ethereal?
Thanks for your valuable comments.
