Hello, How should I deal with Firebase connection lost?
When I'm trying to make a two ways communications from Due serial to ESP8266 then to Firebase, and from Firebase to ESP8266 then to Due, The data cannot be sent to Firebase and It shows Error Firebase : connection lost in my serial monitor, here's my ESP8266 source code

You should call Firebase.ready() repeatedly in loop().

The function Firebase.ready() will return true when device is authenticated. It also handles the authentication processes.

I'm sorry, I still have an error Firebase connection loss in my serial monitor, after i changed my void loop like this,

Firebase.ready();
  if(Firebase.ready() == true){
  if (millis() - sendDataPrevMillis >= 5000){
    sendDataPrevMillis = millis();
    digitalWrite(BUILTIN_LED, HIGH);    
    if(Firebase.RTDB.get(&fbdo, "Actuator/status/flag")){ //jika koneksi berhasil
      ActuatorStatus =  fbdo.to<String>();//kemudian ambil data konversi object fbdo berupa string
      Serial.println(ActuatorStatus); //Kirim nilai ActuatorStatus secara serial
    }else{
      Serial.println("Error Firebase:"+fbdo.errorReason());
//      digitalWrite(BUILTIN_LED, LOW);

    }
    
    if(ActuatorStatus == "Ya0"){
      if (millis() - sendDataPrevMillis1 > 60000){
        sendDataPrevMillis1 = millis();
        kirimFirebase();
       }
   }else if(ActuatorStatus == "Ya110"){
      if (millis() - sendDataPrevMillis1 > 60000){
        sendDataPrevMillis1 = millis();
        kirimFirebase();
       }
   }else if(ActuatorStatus == "Ya111"){
      if (millis() - sendDataPrevMillis1 > 60000){
        sendDataPrevMillis1 = millis();
        kirimFirebase();
       }
   }else if(ActuatorStatus == "Ya120"){
      if (millis() - sendDataPrevMillis1 > 60000){
        sendDataPrevMillis1 = millis();
        kirimFirebase();
       }
   }else if(ActuatorStatus == "Ya121"){
      if (millis() - sendDataPrevMillis1 > 60000){
        sendDataPrevMillis1 = millis();
        kirimFirebase();
       }
   }else if(ActuatorStatus == "Ya130"){
      if (millis() - sendDataPrevMillis1 > 60000){

You can call it once per iteration using if(Firebase.ready()){

For debugging, you should remove tokenStatusCallback function from your code and using the function from the TokenHelper instead.

Firebase-ESP-Client/examples/RTDB/Basic/Basic.ino

Line 22 in c6172d1

#include <addons/TokenHelper.h>

You should check the internet connection because it can't connect to the server even WiFi AP was connected.

From the error shown, you are using the old version library. Please update the library.

Thankyou for your help, it's solved by upgrading the library, but sometimes the esp wifi connection was reset

What do you mean "sometimes the esp wifi connection was reset"?

Calling the function Firebase.reconnectWiFi(true) once in setup is enough.

thankyou for your help mobizt, I have calling the function Firebase.reconnectWiFi(true) once in setup before, but the wifi severally reseting

mobizt Mar 30, 2022

As the name of the function reconnectWiFi, when you set Firebase.reconnectWiFi(true) the library will handle WiFi reconnection in the proper way when the WiFi disconnected by any reason.

If you don't want the library to reconnect WiFi in case you use WiFi management library, calling Firebase.reconnectWiFi(false).

I think it's not resetting but crashed and reboot.

You should debug and monitor the memory usage.
