Re: [lwip-users] LW IP - TCP instantaneous data transmission

[Noam Weissman]

Hi Anand,

 

I am using a similar mechanism and had no problem sending even 100k and more.

 

For example I created an XML configuration file and sent it over HTTP in parts, had no problems…

 

BR,

Noam.

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

 

Regards

Anand

Hi Anand,

 

I do not know what HTTP server you use but what I sent earlier is just a skeleton or pseudo code

for you to get an idea on how to send a large buffer in chunks.

 

If you cannot send the hole buffer (make sense) and you are limited with memory you must wait

for the TCP stack to free the buffer it used to send your data before you can send more. Here comes

the sent call back in hand... it synchronizes sending and freeing of memory.

 

Do you understand that  ?

 

Try and follow the code I wrote in an earlier reply.

 

Good luck,

Noam.

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.
