Hello!
I was wondering what is the proper way to change MAC address of network
interface. Can I just change the contents of netif.hwaddr[] and expect
everything to still work correctly (assuming I also change the MAC

You can change MAC address on your PC, so I'm wondering whether this is
possible and easy with lwIP. "Easy

It was behaving the same way in the git version prior to 2.0.0 and I
guess the "standard" approach to that was to include in your
arch/cc.h file. I think that such issue was reported to the mailing
list
Hello!
Currently in a project with lwIP I'm facing an issue with closing
netconns and I failed to find a solution by myself, so I'm writing here
in hope for some guidance.
Let's say that there are 5 listening netconns, each bound to a
different port, let's say 1001-1005. I'm accepting 5 different

Hello!
For the past few days I have been debugging a hang in one of my
projects which uses lwIP and my C++ RTOS - http://distortos.org/
The networking part of the application is rather simple and consists of
a single functionality (using 2 threads synchronized with mutexes),
which uses netconn AP

Alternative approach to the problem - could someone recommend a GSM
modem, commercially available in reasonable numbers, M.2 interface,
that works with lwIP? Maybe its the Huawei me906e that is the problem
here, who knows...

It is still there.

Hi!
I'm working on an open-source demo project in which there is a MQTT
client talking via PPPoS to a GSM modem. The project also has a RTOS,
so I have threads and synchronization objects.
I'm wondering whether I could connect a MQTT client to a broker
directly from a PPPoS status callback? The s

Forgive my ignorance, but what is a "module" in the lwIP world? (;
