Thank you ESP_Piyush. This already helps me a lot. I can get a copy of the WIfi credentials, thus making it easier on the service engineer to log in, At the same time, I will just make it for the end user as easy as possible to re-login with his phone after the visit of the service engineer. I will ...

I still have this problem finding the wifi credentials and the stored phone link. I tried going through the source code, but that proves very time consuming.
I really hope someone could point me to the right direction. Even if it is just the wifi SSID and password. I found it is stored in a ...

Moreover the service engineer has additional settings available to him, that the end user has no acces to. So yes, a change is needed as well.

I see two options. One could be that, instead of the saved provisioning data, another storage area is assigned for the service engineer for his login. The other otion ...

Thank you very much ESP_Piyush for the very quick answer I will study your suggestion. If, after really studied it, I still have questions, I will come back.

I have an application where I want the customer to be able to read the QR code for provisioning from the build-in display.
To that end I need to access the PROV_xxxxxx number to recreate the QR code.
Does anyone know where I can find this prov code? I started digging through the source code, but it ...

Thank you so much ESP_Piyush for your suggestion! Once I started to read, I realized I had, when I started, created a bunch of tasks with some stack size "just to be safe". I never touched them again after they worked.
Really stupid! Thanks, I expect to be rid ,for a while at least, of the memory ...

As I am getting close to the RAM limit, I wonder if changing to a more modern ESP32 module (ESP32-S3?) would be beneficial. Could anyone please comment. I looked at the different specifications, but with the RAM split up the way it is, it is difficult for me to be certain.
I use now the ESP32-WROOM ...
