Hi,
I'm using lwip 2.0.3 with freertos.
I'm running tcp server in my Linux pc and tcp client on atmel
microcontroller with lwip 2.0.3.
I got succeeded in establishing a successful tcp connection with my Linux
pc,but when I start sending tcp messages from client using *send* function I
see it stops sending after 1 or two minutes always.
I observed that it is clubbing all the messages and try to continuously
retransmit.please help me fixing this issue.
Things like this have *very very* often been the result of invalid
multitasking in the lwIP core functions. Less often but on second place
are buggy drivers.
Try reading the docs (especially "Common pitfalls", see
http://www.nongnu.org/lwip/2_0_x/pitfalls.html, does anyone having
problems ever read this?) and see if you have buggy code running.
To check multithreading problems semi-automatically, upgrade to latest
git master and use LWIP_ASSERT_CORE_LOCKED() - check the existing ports
in contrib/ports for examples of how to setup these checks with your OS.
