Undefined Error

[rohitmsaxena]

When I run my code on my esp8266 it connects to the wifi and then attempts to connect to firebase once, fails, and then gives no error. It literally just says "failed at..." and then nothing so there is no error.

Can someone explain to me what I am doing wrong??

This is my code:

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

#define WIFI_SSID "Gumby"
#define WIFI_PASSWORD <something>
#define FIREBASE_DB_URL "http://<something>.firebaseio.com"
#define FIREBASE_DB_SECRET_KEY <secret>

void setup() {
  Serial.begin(115200);
  Serial.println("code running");
  pinMode(D1, OUTPUT);
  pinMode(D2, OUTPUT);
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  while (WiFi.status() != WL_CONNECTED) {
    Serial.println("attemping to connect to wifi...");
    delay(500);
  }
  
  Firebase.begin(FIREBASE_DB_URL, FIREBASE_DB_SECRET_KEY);
  Firebase.stream("/automation");
  Serial.println("done with setup");
}


void loop() {
  //Serial.println("looping...");
  if (Firebase.failed()) {
    Serial.println("streaming error");
    Serial.println(Firebase.error());
  }
  
  if(Firebase.available()){
    String output = Firebase.getString("value");
    Serial.print("output: ");
    Serial.println(output);
    if(Firebase.failed()) {
      Serial.print("failed at...");
      Serial.println(Firebase.error());
    }
  } else {
    Serial.println("error firebase not available");
  }
}

Same, Firebase.error() is blank.

It may be because you have your host defined as:

#define FIREBASE_DB_URL "http://<something>.firebaseio.com"

Try without the "http://", as:

#define FIREBASE_DB_URL "<something>.firebaseio.com"

I hope this helps you

@JuanPTM Thanks for answering this question!

@Mastermind42 @srph do you still have issues with the libraries?

IIRC @JuanPTM's suggestion fixed it for me.

filed #349 to improve error message.
