Thanks Noam, I got what you are saying. I could not work on this yet. I will
try as you suggested.

I'm afraid I don't really understand your questions. As Noam said, have
a look at the http server, I guess you can learn everything you need
from there.

Hi Simon,
Once the data is sent and the acknowledgement is received; I think, LWIP is
supposed to increment the tcp_sndbuf( ) value so that the next set of data
can be sent right ? Should I do something in the http_sent callback to make
room for next set of data ?
Thanks

Calling tcp_output() sends the data, but that doesn't mean the buffer is
free afterwards: it stays allocated until the remote host acknowledges it.
At this point, lwip calls your 'sent' callback.

Hi Dirk,
I agree, this function is called when the data is sent to the client. In my
case this will be called only once when the buffer is full (8*1460 bytes)
and the data is sent to the client. But, I am adding data to the buffer
with tcp_write( ) with the increments of around 2 k bytes every few

Hi,
I am using LWIP (Raw TCP mode) (in FreeRTOS) for handling http page requests,
construct the web page and send the page to the client. I have set the
TCP_SND_BUF as 8
Check out tcp_sent() callback, it is called after data was successfully
sent to remote station.

Hi,
I am using LWIP (Raw TCP mode) (in FreeRTOS) for handling http page
requests, construct the web page and send the page to the client. I have
set the TCP_SND_BUF as 8*TCP_MSS where TCP_MSS is 1460. There will be only
one client / browser connecting to the system at a time.
In the receive call
