Re: [lwip-users] lwIP delays outgoing TCP packets by up to 500ms

[Pîrvu Mihai]

Again, it's probably not be the wrong approach, it's just what I've been told on this thread:

https://lists.gnu.org/archive/html/lwip-users/2016-06/msg00055.html

Since it worked for me at that moment, I just let it like that, and reading the responses here confirms that it's the correct approach if you don't want to wait for the delay.

I think you might have missed reading the documentation: tcp_write enqueue data, tcp_outout tries to send it. You always have to call both.

I actually found the recommended call flow on wiki (Here: http://lwip.wikia.com/wiki/Raw/TCP ) after Mihai mentioned using tcp_output().

And yes, I haven't fully read the docs/wiki yet, since I am trying to fix existing code written by someone else - who must have missed that...

However, Mihai mentions that calling tcp_output() might be the wrong approach... Is it really?

Thanks!
