Uploading data to firebase using NodeMCU

[Anudeep]

Thanks, @rafitc99. But even this didn't solve my problem!!
I have changed the code in the below format...

#include <ESP8266WiFi.h>
#include <FirebaseArduino.h>       

// Set these to run example.
#define FIREBASE_HOST "syndinnovate-1.firebaseio.com"
#define FIREBASE_AUTH "AIzaS********************7hKQe4uPbfUKHc"
#define WIFI_SSID "SSID"
#define WIFI_PASSWORD "PASS"

void setup() {
  Serial.begin(9600);
  delay(1000);                
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);                                     //try to connect with wifi
  Serial.print("Connecting to ");
  Serial.print(WIFI_SSID);
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print(".");
    delay(500);
  }
  Serial.println();
  Serial.print("Connected to ");
  Serial.println(WIFI_SSID);
  Serial.print("IP Address is : ");
  Serial.println(WiFi.localIP());                                            //print local IP address
  Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);                              // connect to firebase                                                               //Start reading dht sensor
}

void loop() {                                                             //Convert RainSensr data into string
  
  Firebase.pushString("/NEW", "No");   
  delay(1000);//setup path and send readings
  Firebase.pushString("/NEW", "Yes");                                //setup path and send readings
  delay(1000);//setup path and send readings
}

@Anudeep Ok , compilation part is clear .did you getting anything on the firebase side ? Any erros ?

[Anudeep]

@salmanfaris Nothing, No errors!!
Do I need to change anything in Firebase settings or something?

[Anudeep]

@salmanfaris Thanks for the support!!
I finally resolved the error. I have taken FIREBASE_AUTH as apiKey instead of Database secrets.

@Anudeep Great . Glad to know that it is solved , Keep hacking

@Anudeep Hello Anudeep could you please help me out by elaborating the fix to get rid of that error?
Thanks in advance.

Hello @Palani, In the Firebase, there are two types of storage,

1. Cloud Firestore (Very recent one & NoSQL database)
2. Realtime Database (To which we upload the data using NodeMCU)

In the Arduino Code, you can see that there is a variable named FIREBASE_AUTH.

This variable should be assigned to the Database secret. This you can find in Project Settings -> Service accounts -> Database Secrets.

My mistake is, i have mistakenly assigned thay to Web API key. This is found at Project Settings -> General.

The error can also occur when u don't initialise a proper realtime database in Firebase. (This is not my case).

@Anudeep Thanks a lot m8, I actually made a very silly mistake of including the https:// while entering FIREBASE_HOST, where I must have entered the Domain name alone and removed the https:// extension.

Thanks again for replying that quick. Cheers.
