Thank you.

I will only need to get and send from an ESP32, I’ll see next week.

Hi.
We have these tutorials to control ESP32 hardware via Firebase:
– https://randomnerdtutorials.com/?s=firebase

However, we don’t use MIT APP Inventor in any of them.
We use web apps to create an interface.

Regards,
Sara

I’ve seen that Firebase can be used in MIT App Inventor with an extension, and the ESP32 can communicate with Firebase. Which project do you suggest for ESP32 hardware to and from Firebase?

Hi.
Open the Terminal window with a right click on the mouse. Then, select open as admin or something similar.

Sara

Hi.
I’m sorry, but I didn’t understand your question.
Are you having issues with our tutorial, or is it with your modified version only?
Regards,
Sara

Looks like the path info was filtered out. It should be Userid/deviceID/date/data. The dataStringPath would be similar: const dataStringPath = ‘Userid/deviceID/date’;

I am trying to adapt your instructions to use on my own project but I’m not seeing any data/records being displayed on the web page. Can you recommend a way to troubleshoot this? It’s probably a path issue but I’ve tried several changes and deployed them but still nothing and I’m not sure how to debug this.

My path looks similar to ///. The path, as defined in app.js is //

Can you recommend some troubleshooting tips as to how to debug this?

Thanks.

Hi.
You’re probably wrong credentials or wrong database URL.
