ESP8266 not connecting to firebase!

[JaysArtworks]

I've a problem connecting the ESP8266 board to Firebase (sketch is correct), but the board connects to the wi-fi, I've already updated the Arduino Json Library and i reinstalled the Firebase library, but nothing (2 months ago I had no problems with the connection).

Same for me, it fails to read and write. Although Firebase.begin gives success. I am using DB Secret.

try this : #369

I'll try this solution later.

@prj-x I've I tried to change the Firebase fingerprint, but nothing...it is working for you?
I'm a bit worried, beacuse i have to finish a project for school...

[santoshn547]

I have tried changing the Firebase fingerprint as well as updating the library itself but no use ?
Firebase begins connection without any error but
Unable to read data from firebase and streaming also fails,
Does Anyone know the solution ?

I Changing the firebase fingerprint, nothing. I'm try get new firebase library complete, but don't work.
Help-us!!

try use old libary for a while..
This link --> https://github.com/RaemondBW/firebase-arduino

but this library doesn't work for stream function
just simple function like "get" and "set" is work.

download and edit to newest fingerprint.. (FirebaseHttpClient.h)

Using the old library in esp8266 it is reseting.

it shows the following exception :
Exception (28):
epc1=0x4020e636 epc2=0x00000000 epc3=0x00000000 excvaddr=0x00000000 depc=0x00000000

and it continuously resets .
I can say that my sketch is error free, Its because of using old library .
Does anyone know the solution ?
Stuck in a project thats in due.

@santoshn547 can i see the code ?

The above Sketch was working fine before 5 days.

Hi everyone
here is the solution that is working for me.

1. download the file from the link : https://github.com/firebase/firebase-arduino/files/2268787/firebase-arduino-master.zip
2. extract the zip file.
3. copy everything from the file and paste and replace into the location C:\Users\hossa\Documents\Arduino\libraries\firebase-arduino-master
4. now download this file from the link https://github.com/firebase/firebase-arduino/files/2268800/FirebaseHttpClient.zip
5. extract it and paste and replace the file into C:\Users\hossa\Documents\Arduino\libraries\firebase-arduino-master\src

@santoshn547
sorry the old library doesn't work for stream function
but basic function like "get" and "set" is work.

[santoshn547]

@adamrabbani
Using the below code only returns 0 while the data in firebase is 1.
I am not getting data from firebase it is blank when converted to String.
My Url and Authcode is right.
MyFirebase.begin(firebaseURl,authCode);

FirebaseObject object = MyFirebase.get(path);
bool led1 = object.getBool("001");
bool led2 = object.getBool("002");

Is my code right for the old library ?

@kabir1995 What code are you using to begin connection as well as to get bool from firebase ?

[JaysArtworks]

@kabir1995 Thank you very much man! Now the code is working, I did all the steps which you said above, and i deleted the #include <ArduinoJson.h> from the code, because when i upload the code with the Json Library included, it gives me errors, anyway all is working, so thank you again!

[santoshn547]

@JaysArtworks
What code are you using for reading data from firebase ?
