PTC4PU won’t connect to mqtt

[Venderwel]

Hi all,

It looks like my PTC4PU will not connect to mqtt. It’s on a AZdelivery ESP32 with ESP32 devkit (it looks like I need to use that one for ESP32-WROOM).

I don’t see a thing in my mqtt broker, while my Layoutcontroller is visible in there. They use the same network settings.
This is what I get on my com port:

Come to think of it, I’m not really sure it connects to wifi.

Hi vanderwel,

This is a known issue in the 0.4 firmware. For my MC4PU I’m using the 0.3 version of the controller and Mattzo library. For the layout controller 0.4.1 works fine.

Hope this helps!

[Venderwel]

Sadly not. I think I’m doing something wrong. Is there someone Who is willing to help me out and maybe take a look with Zoom or Teams?

Hi, unfortunately I cannot help you via teams for the coming week.

What worked for me yesterday when my layout controller couldn’t connect anymore was to clear the wifi flash. If you’re using the Arduino IDE this is an option under ‘sketch’. Usually this is set to ‘sketch only’ but you might want to try to set it to ‘sketch + WiFi’. If that doesn’t work you can try the ‘flash all’ option but note that this also clears your Mattzo ID, which means you need to change the rocrail settings (except for the MC4PU, so you’re lucky).

Hope this helps!

PS I’m not behind my computer so the names between quotes might be slightly different in the Arduino IDE.

[Venderwel]

There’s no such option with the ESP32 boards.

[Venderwel]

Rrrrrrrrr……ofcourse. Always quadruple check the board and use the right one! Now it seems so connect!!! On to the next station in my project!
