[lwip-users] lwip on pico_w

Hi Christoph

Chrrisoph wrote "Yes, I’m using lwIP on Picos as well. In my case, the MQTT client was a bit of a pain and kept throwing me into random panics too. The problem is that it doesn’t take the state lock. Basically, all calls to mqtt_* functions have to be guarded by cyw43_arch_lwip_begin() / cyw43_arch_lwip_end(). Once I did that, everything became quite stable for me."

First of all thank you for the information.  This provides a path forward to getting the random panics resolved.  I am very new to using lwip & pico_w.  Can you provide a link to example code the shows cyw43_arch_lwip_begin() / cyw43_arch_lwip_end() with mqtt_ functions.

 

What are using as the broker?  I am using mosquitto on a RPi.  I have been working on RPi Bare Metal. I can a broker  on hardware/QEMU   https://github.com/develone/Ultibo_Projects/tree/master/Pauls-ultibo-mqtt
