Hello, I would like to test the TCP transfer speed between a device running lwIP 1.4.1 using Raw API (192.168.0.100) and my laptop (192.168.0.1). I have 2 questions: 1/ The first part of the trace is

Nope. Whether the extra code complexity (=> size increase) will mean it ever happens I'm not sure. Jifl -- eCosCentric Limited http://www.eCosCentric.com/ The eCos experts Barnwell House, Barnwell Dr
Yeah, so I broke it adding the tcp_output_nagle. I am emulating netconns but with NO_SYS=1 and used that code as a reference. I'll take out the call. Thank you. That was a good read. As is Nagle's f
Umm. I can describe the set up I have, if that helps. Actually, the code is all available here if you want to look at that... http://interactive.freertos.org/entries/20290712-freertos-win32-project-
Hi all, I am coming back with two captures regarding lwip's retransmit mechanism NonAVR.pcap is captured on a non-lwip device, and you can see even ACk is stopped at packet 48, this TCP server keeps
Thank you.I want to run lwip on win2008 64bit system,so I want to set MEMP_NUM_NETCONN a large value. Message: 2 Date: Wed, 24 Nov 2010 14:13:41 +0000 From: Kieran Mansley <address@hidden> Subject: R
Thank you, Simon! 1) I assume you made a typo when commenting TCP_WND? "This must be at least * (2 * TCP_MSS) for things to work well" seems apply to TCP_SND_QUEUELEN, and since TCP_SND_QUEUELEN 6 *
tcp_output() actually is the place where the nagle algorithm is implemented! And no, there is no global option to disable the nagle algorithm. Simon -- Neu: GMX FreeDSL Komplettanschluss mit DSL 6.00
Hi all: I am having performance problems with TCP and I wanted to understand what is going on. It could be the Nagle algorithm. My devices exchange many small to medium-sized packets. Ideally, I woul
Hi, So maybe enlarge MEMP_NUM_PBUF 100-150 your have the memory for it J Noam. From: lwip-users [mailto:lwip-users-bounces+address@hidden On Behalf Of Itzik Levi Sent: Tuesday, November 07, 2017 6:15
Hi, Check that you have MEMP_NUM_PBUF 50 or more that MEMP_NUM_TCP_PCB is 15 or more The above may help, I think. Noam. From: lwip-users [mailto:lwip-users-bounces+noam=address@hidden] O

Unfortunately, enabling Nagle did not do the trick, still got the same result. :( On Tue, Nov 7, 2017 at 4:20 PM, Itzik Levi <address@hidden> wrote: Thanks for the reply! Actually, the end goal is
Hello, Try call tcp_output() function after tcp_write if you are using lwip1.4.x. After lwip 1.4.x, tcp_write() just enqueue your packet but will not send it. lwip 1.3.x will immediately send your pa
Hi, You must define this in your lwipopt.h take a look in stats.c file. You will need to complete the LWIP_PLATFORM_DIAG to get your data out. Jonathan Le 2014-01-29 16:50, Dave Sandl a écrit
Thanks I will try that, is it a serial / printf output? What am I looking for in the debug? Dave Date: Wed, 29 Jan 2014 15:23:13 -0500 From: address@hidden To: address@hidden Subject: Re: [lwip-users

Well, I am using lwip 1.3.2 I do understand that on every call to tcp_write the snd_queuelen is incremented but I do not understand why it is not decremented when I call tcp_output. Also take into co
