  1. Are you using the us-central server for your firebase project ?
  2. You have an empty socket in your fourth if condition....
  3. Sometimes, your aia project need to interact with firebase (e.g. set a dummy tag/value) in order to initialise the dataChanged event

  1. yes
  2. corrections done
  3. can you help I am not getting what you want to say

I have just tested your aia. You have no data in Firebase (or your data is not changing), so nothing will be returned....

5

can you confirm if my code is ok or if any corrections are needed. I think its because my data is not changing.

this the url for my database

Your blocks look OK, and firebase is accepting values from the aia project, but I am guessing you want to load values into firebase from your ESP32 device ? ( I cannot provide any advice on that part)

yes, I want to display real time data obtained from ESP-32 in the app.(No problem thankyou for your quick response)

Where is the ESP-32 code?
