Hi.
Double-check that the user you created and corresponding password is the same you’re using in your code.
Also, double-check the database URL.

Hi.
It still works using the deprecated library on VS Code.
The interface on Firebase console has changed the colors, but the menus are the same.

Are you stuck at some point in the process?

Sara

I really like and use your tutorials. Congratulations on your work.

Now I can’t use more Firebase.
The firebase access has changed and the library is Deprecated.

See msg at GitHub.

I successfully logged into the firebase. But in the loop() part, the error “connection lost” keeps comming. I am using v 2.3.7. The newest version gave me error “connection failed”

Hello,

I have followed this tutorial and successfully build a project using Esp8266 and Firebase Realtime Database. Everything works fine except that when my project is kept idle for like an hour or something it gives me this error:

Token info: type = id token, status = on request
Token info: type = id token, status = error
Token error: code: 400, message: INVALID_EMAIL

Please Note that my Token and Database URL are totally fine. As far as the Email is concerned, im using the anonymous authentication of firebase so that the ESP can connect directly without any human interaction.

Thank you.
