Setting/number failed

[ArunN21]

Unable to connect to firebase ,please help ,urgent

For Firebase_demo code

[mrunmaydarpan]

same thing happening with my nodemcu also

[vvinu9876]

even i have the sane problem...

[valdiney]

I´m with the same problem and i don´t know what i should do to solve!

[opit7]

You need to use the newest headerfiles. You can download the repo as a zip and inlcude the neccesary files by hand. This is not an elegant solution, but it works.

[heriveltogabriel]

I'm having the same problem, I downloaded it again, updated but it does not work.
Someone?

[valdiney]

I downloaded it again too, but not work.

[heriveltogabriel]

Guys, I've been able to solve my problem.
I removed the bar "/" from the end of the url

Ex:
#define FIREBASE_HOST "test.firebaseio.com"

That's Work!!!

[valdiney]

I removed the second parameter of the method Firebase.begin(FIREBASE_HOST); I passed the firebase host only and work to me!!

[axelsilvaferreira]

Hi, I had the same problem. I was using the wrong token. Apparently you have to go to Firebase "Settings" > "Service Accounts" tab > under Legacy Credentials click "Database Secrets" > select your firebase project anda click "Show".
The following video shows how to get the token.

[valdiney]

Thanks bro. I will watch your video! In my case I removed the key.

[axelsilvaferreira]

It’s not my video, but I hope it will help. :)

[proppy]

Thanks for figuring that out!

[youtechnoid]

After the strive of whole day long, at last I reached to solution that the file "FirebaseHttpClient.h" had a problem.
(C:\Users\XXXXX\Documents\Arduino\libraries\firebase-arduino-master\src )

Just change the fingerprint in "static const char kFirebaseFingerprint[]" to another one [without : ] . You can find one for yours here"https://www.grc.com/fingerprints.htm". Just scroll down and put your firebase host (ie. https://xxxxxxx.firebaseio.com/) here.

found same kinda problem here "#236"

[adamrabbani]

@ArsamHashmi I think fingerprint not change from 1 year ago.. because i use old libary 1 year ago..
recently i check still remain the same

[ArsamHashmi]

@adamrabbani I'm new to this stuff so please correct me if I'm wrong. I tried it on old library today. It refused to work on the fingerprint found in the firebase console idk why but it worked like a charm when i used the upper link to find fingerprint.
A little bird told me that it's only compatible with version 1.6.9 of arduino ide. Not sure about this one

[adamrabbani]

@ArsamHashmi
i use the newest arduino IDE 1.85.
i think library you using is old libary but old fingerprint..
so when you change old fingerprint to new fingerprint.. so working perfectly..
btw, what version library are you using ?

use this library for while.. https://github.com./RaemondBW/firebase-arduino.
this old library but the newest fingerprint so work smoothly..
*but function like "stream" doesnt work

[adamrabbani]

@ArsamHashmi just now firebase fingerprint has changed..

[ArsamHashmi]

@adamrabbani yesterday I came across the same thing. I'm 100% sure that this tweak can solve the problem. Thanks for updating

[proppy]

Fingerprint updated with #368

[mesut25]

Bütün gün süren gayretten sonra, en sonunda "FirebaseHttpClient.h" dosyasının bir problemi olduğu sonucuna vardım.
(C: \ Users \ XXXXX \ Documents \ Arduino \ kitaplıklar \ firebase-arduino-master \ src)

Sadece parmak izini "statik const char kFirebaseFingerprint []" dosyasında başka bir [:] olmadan değiştirin. Burada sizin için bir tane bulabilirsiniz " https://www.grc.com/fingerprints.htm ". Sadece aşağı kaydırın ve firebase sunucunuzu buraya yerleştirin (ör. Https://xxxxxxx.firebaseio.com/ ).

Burada aynı sorun bulundu " # 236 "
sorguma sonucu
AN ERROR OCCURRED

[Vlequns]

That's worked for us, thanks a lot.

[leozhoushu]

I tried everything you guys mentioned above (check the fingerprint, switch to the old library but with the new fingerprint, delete key), but none of them work for me.... omg, what can I do now, pls help...

[rexoravbiere]

@leozhoushu please am facing the same problem here, i have changed the fingerprint, tried removing the secrete-key, tried old library, but non of these solution work for me, please if you find solution do let me know, thanks

[khoiwalvikram2]

Just upload your sketch and you getting Setting/number failed and then press reset button on your esp8266 nodemcu than its been working great for you. it is worked for me

[rexoravbiere]

@khoiwalvikram2 thank you and all for your help, now working!, my problem was actually from the host url (was https://iothome-xxxxx.firebaseio.com/ instead of iothome-xxxxx.firebaseio.com )

[stackblogger]

Its fixed!!!

go to C:/Users/{username}/My Documents/Arduino/libraries/firebase-arduino-master/src

open FirebaseHttpClient.h file, and paste following fingerprint =>

6F D0 9A 52 C0 E9 E4 CD A0 D3 02 A4 B7 A1 92 38 2D CA 2F 26

Now build and upload the sketch to NodeMCU using Arduino IDE

[joy2012bd]

I am facing same problem.Setting / number failed:
Please help.

[Mayoogh]

@joy2012bd Updated fingerprints ?

[joy2012bd]

@joy2012bd Updated fingerprints ?

Yeah.The problem is solved.But another issue with get value. Firebase.getString("S2").toInt(); always return 0. Any suggestion? What is the perfect way to get value of a key? Is .Firebase.getFloat() enough to get all types value?

[Mayoogh]

@joy2012bd I too had similar issue. Try this 2 methods

1. Delete the location S1 from firebase.
   In void setup() add Firebase.set("S1", 0);

2. Inside void loop
   int S1_value = firebase.getInt("S1");

Let me know if it fix the issue.

Thank you so much.It worked for me.But another issue.After running few seconds it returns error in Serial monitor Trying to reconnect setting number failed: And it does not stop until the reset switch is pressed.

I am using the code below.

#include <ESP8266WiFi.h>
#include<FirebaseArduino.h>
#define FIREBASE_HOST "***"                     //Your Firebase Project URL goes here without "http:" , "\" and "/"
#define FIREBASE_AUTH "***"       //Your Firebase Database Secret goes here
#define WIFI_SSID "***"             //your WiFi SSID for which yout NodeMCU connects
#define WIFI_PASSWORD "***"        //Password of your wifi network 

void setup() 
{
  Serial.begin(115200);                                                   // Select the same baud rate if you want to see the datas on Serial Monitor
  WiFi.begin(WIFI_SSID,WIFI_PASSWORD);
  Serial.print("connecting");
  while (WiFi.status()!=WL_CONNECTED){
    Serial.print(".");
    delay(500);
  }
  Serial.println();
  Serial.print("connected:");
  Serial.println(WiFi.localIP());

  Firebase.begin(FIREBASE_HOST,FIREBASE_AUTH);
  Firebase.set("loads/switch1",1);
}
void firebasereconnect(){
  Serial.println("Trying to reconnect");
    Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
}

void loop(){
  if (Firebase.failed()){
      Serial.print("setting number failed:");
      Serial.println(Firebase.error());
      firebasereconnect();
      return;
  }

  int S1_value = Firebase.getInt("loads/switch1");
  Serial.println(S1_value);
}

Any suggestion will be highly appreciated.Thank you.

Not sure about it. Try without firebasereconnect()
you can refer to this code

found same kinda problem here "#236"

Thanks. It worked!

[Alpha-1729]

Try this method:
use latest firebase arduino library from the github.
use firebase 5.13.5
use esp8266 board manager 2.6.0

use firebase database rule like this
{
"rules": {
".read": "true",
".write": "true"
}
}

use firebase url like this : ######.firebaseio.com

then everything will work

[Alpha-1729]

dont use the firebase token in the script

[WareBV]

dont use the firebase token in the script
Awesome, like butter!!

[vienbu]

hi, i make a same error, i was change fingerprint but it still don't work, can anyone tell me how to u slove it, please

[cosme098]

Well, I managed to solve my problem which was the same as the ones above, I did the following steps, I changed the esp8266 core to version: 2.4.1, I put the json arduino to: 5.13.1 and finally, I did it the video steps:https://www.youtube.com/watch?v=ZZ5JvSA-Ed8&ab_channel=TrickSumo

[cosme098]

@vienbu follow this video, I had the same problem:https://www.youtube.com/watch?v=ZZ5JvSA-Ed8&ab_channel=TrickSumo

[stackblogger]

The error comes when Firebase Fingerprint is expired and your NodeMCU keeps trying to connect to Firebase.
The solution of the error is to generate a new fingerprint and insert in code.
The steps on how to generate and new key and insert is here- https://stackblogger.com/setting-number-failed-firebase-nodemcu/

[zeynepbaysoy]

Hi, I make a "setting/number failed error". I'm using nodemcu esp8266. I installed arduino json 5.13.1 version and esp8266 2.4.1 version and ı updated firebase fingerprint. But it doesn't work for me :( Please help.
