"Connection refused" using Version 2.8.6 (used to work 4 months ago)

[samlidippos]

Hi!

I am using Firebase Esp8266 Client v2.8.6 and Esp8266 sdk v2.5.0.
My code was:

#include "FirebaseESP8266.h"
#include <ESP8266WiFi.h>
#include <WiFiClient.h>
#include <ESP8266WebServer.h>

FirebaseData firebaseData;
String FBPath;
#define FIREBASE_HOST "myprojectname.firebaseio.com"
#define FIREBASE_AUTH "xxxxxx"

int current_luminosity = 0;
void setup(void)
{
  Serial.begin(115200);
  WiFi.begin(MY_ROUTER_SSID, MY_ROUTER_PASS);
  delay(500);

  int i = 0;
  while (WiFi.status() != WL_CONNECTED) { // Wait for the Wi-Fi to connect
    delay(300);
  }
  delay(500);
  Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH);
  Firebase.reconnectWiFi(true);
  delay(1000);
  FBPath = "/";
  FBPath .concat("sample");
  FBPath .concat("/Luminosity");
  Serial.println(FBPath );
  FirebaseJson updateData;
  FirebaseJson data;
  data.set("Luminosity", 50);
  current_luminosity = 50;
  updateData.set(sample, data);
  Serial.println("Trying to update data");
  if (Firebase.updateNode(firebaseData, "/", updateData)) {

    Serial.println("Slot for this device was created at the cloud");

  } else {
    Serial.println(firebaseData.errorReason());
  }
  delay(100);
  Firebase.setStreamCallback(firebaseData, streamCallback, streamTimeoutCallback);
  Serial.println("Stream callbacks setup completed. Streaming from Firebase!");
  if (!Firebase.beginStream(firebaseData, FBPath))
  {
    Serial.println(firebaseData.errorReason());
  }
}

void loop(void)
{}

void streamCallback(StreamData data)
{

  if (data.dataType() == "int")
  {
    Serial.println(data.intData());
  }
}


//Global function that notifies when stream connection lost
//The library will resume the stream connection automatically
void streamTimeoutCallback(bool timeout)
{
  if (timeout) {
    //Stream timeout occurred
    Serial.println("Stream timeout, resume streaming...");
  }
}

What I want with that code is super simple.
I just want the ESP to connect to the local WiFi, and then create a node in a firebase realtime DB, from which I will stream the changes.
It used to work 4 months ago, when I last used it. But now I get an error "connection refused" after "Trying to update data".
I know that the version of the library is old, but I started with this as it was working fine. What could have gone wrong?

You need to update the ESP8266 core sdk because many things removed from and add to core libraries and C++ compiler was updated from v4 to v10 which breaks the compatibility of all libraries too.

If you want to use the latest version of library, you need to update the core sdk.

As I replied, you need to update core sdk to at least 2.7.x if you want to use the latest version library.

yes I saw that. I just wonder which library version requires less than 64kB of SRAM. I think the latest one needs larger board with 128kb of SRAM.

128k flash not ram

This paragraph is for devices other than esp8266.
