My project worked perfectly until 2020/02/17 1:28:55 AM and suddenly it crashed. error - firebase failed there is no issue with wifi or the Node MCU libraries I used - firebase library : https://github.com/FirebaseExtended/firebase-arduino JSON library : https://github.com/bblanchon/ArduinoJson/tree/v5.13.1

Please help me and thank you for your time.

This is my demo code:

Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH); }

int n = 0;

void loop() { // set value Firebase.setFloat("number", 42.0); // handle error if (Firebase.failed()) { Serial.print("setting /number failed:"); Serial.println(Firebase.error());

Update the fingerprint

static const char kFirebaseFingerprint[] = "03 D6 42 23 03 D1 0C 06 73 F7 E2 BD 29 47 13 C3 22 71 37 1B"

Hi I also had the same issue and I updated the fingerprint. After updating the latest fingerprint, data was uploaded to Firebase. But, the NodeMCU crashes automatically after sending data for a while. The Serial Monitor displays an exception. After decoding the exception, my understanding was that the issue was with the "Firebase.getInt" code parts. It works when put in "Void Setup", but results in an exception when it is placed in "Void Loop". I have been unable to fix the issue for about a week now. Please help.

Here is my code:

//D0 = 16; //D1 = 5; //D2 = 4; //D3 = 0; //D4 = 2; //D5 = 14; //D6 = 12; //D7 = 13; //D5 = 15; //D9 = 3; //D10 = 1;

@Danin066 did you check your firebase database, is the data is sending to the database or not?

Hi, I have the same problem but I already actualized the fingerprint and still no working. I installed the last Arduino firebase library, the ArduinoJson 5.13.1 library, and the ESP8266 2.5.2 board.

I have tried many things, uninstalling libraries and looking for new ones but it doesn't work.

I use this fingerprint ("03 D6 42 23 03 D1 0C 06 73 F7 E2 BD 29 47 13 C3 22 71 37 1B")

The problem is (setting /number failed:), so the firebase.begin is okay

Thank you all!

anyone having still error

Hola , también tuve el mismo problema y actualicé la huella digital. Después de actualizar la última huella digital, los datos se cargaron en Firebase. Pero, el NodeMCU se bloquea automáticamente después de enviar datos por un tiempo. El monitor serie muestra una excepción. Después de decodificar la excepción, entendí que el problema estaba en las partes del código "Firebase.getInt". Funciona cuando se coloca en "Configuración vacía", pero da como resultado una excepción cuando se coloca en "Bucle vacío". No he podido solucionar el problema durante aproximadamente una semana. Por favor ayuda.

Aquí está mi código:

// D0 = 16; // D1 = 5; // D2 = 4; // D3 = 0; // D4 = 2; // D5 = 14; // D6 = 12; // D7 = 13; // D5 = 15; // D9 = 3; // D10 = 1;
