Damon, Antoine Hi I use LWiP for my project. I run the stack
on an embedded board (with blackfin BF527 processor). I use the webserver too.
I have created a webpage which is located on my webserver. I would like to use
this webpage to show some dynamic data. I couldn’t send some big packets. After
two segments, the stack send an acknowledge of the end of transmission.
On my webpage, I get the data with the command xmlhttprequest. I copy hear the main lines I could see with
the sniffer Wireshark 192.168.1.1
192.168.1.11
HTTP
GET /polyline_c.xml HTPP/1.1 192.168.1.11
192.168.1.1
TCP
TCP segment of reassembled PDU 192.168.1.11

http> vaultbase [FIN,ACK] Seq=1111 ack=444 Win=8192 Len=0 …. I configured the TCP IP stack to accept the
large packet size (file lwipopts.h), but this change nothing. After the
transmission of two segments, the transmission is closed. I attached the file of trace and the file
of the Stack configuration. Thanks for your help. Best regards.
