I am following Firebase Web App with ESP32. After 1 hour I get the token expired message.
From Firebase:”Firebase Authentication sessions are long lived. Every time a user signs in, the user credentials are sent to the Firebase Authentication backend and exchanged for a Firebase ID token (a JWT) and refresh token. Firebase ID tokens are short lived and last for an hour; the refresh token can be used to retrieve new ID tokens.”
Seems like I never get a refresh token.
I have checked my code, checked Firebase console to make sure I’m signed in, Firebase rules are read True and write True, user ID prints in serial monitor.

Hi.
What is the exact sketch that is giving you trouble?

Hi Sara, I am following data logging portion of the Firebase Web App but replacing readings instead of logging them. Here is the code.

It works well except for the expiring token after an hour.

Hi.
I think you’re missing the line of code that checks that Firebase is ready (that line also refreshes the token if needed).
if (Firebase.ready() && (millis() - sendDataPrevMillis > timerDelay || sendDataPrevMillis == 0)){ sendDataPrevMillis = millis();
Take a look at the following data logging example – take a look at the loop() section
I hope this helps.
Regards.

Yes you are right. I left that line out as I did not need the timer not realizing that function was in there.
Thanks! , Rob
