Esp firebase and rfid

using : esp8266 (nodemcu) and uhf-rfid

I am trying to send data from UHF-RFID to firebase using 'Firebase_ESP_Client.h' and 'Wiegand' libraries in the following links,

Firebase_ESP_Client.h

they both worked well in their examples,

I followed this code: from (ESP8266 NodeMCU: Getting Started with Firebase (Realtime Database) | Random Nerd Tutorials)

#include <Arduino.h>
#if defined(ESP32)
  #include <WiFi.h>
#elif defined(ESP8266)
  #include <ESP8266WiFi.h>
#endif
#include <Firebase_ESP_Client.h>

//Provide the token generation process info.
#include "addons/TokenHelper.h"
//Provide the RTDB payload printing info and other helper functions.
#include "addons/RTDBHelper.h"

// Insert your network credentials
#define WIFI_SSID "REPLACE_WITH_YOUR_SSID"
#define WIFI_PASSWORD "REPLACE_WITH_YOUR_PASSWORD"

// Insert Firebase project API Key
#define API_KEY "REPLACE_WITH_YOUR_FIREBASE_PROJECT_API_KEY"

// Insert RTDB URLefine the RTDB URL */
#define DATABASE_URL "REPLACE_WITH_YOUR_FIREBASE_DATABASE_URL" 

//Define Firebase Data object
FirebaseData fbdo;

FirebaseAuth auth;
FirebaseConfig config;

unsigned long sendDataPrevMillis = 0;
int count = 0;
bool signupOK = false;

void setup(){
  Serial.begin(115200);
  WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
  Serial.print("Connecting to Wi-Fi");
  while (WiFi.status() != WL_CONNECTED){
    Serial.print(".");
    delay(300);
  }
  Serial.println();
  Serial.print("Connected with IP: ");
  Serial.println(WiFi.localIP());
  Serial.println();

  /* Assign the api key (required) */
  config.api_key = API_KEY;

  /* Assign the RTDB URL (required) */
  config.database_url = DATABASE_URL;

  /* Sign up */
  if (Firebase.signUp(&config, &auth, "", "")){
    Serial.println("ok");
    signupOK = true;
  }
  else{
    Serial.printf("%s\n", config.signer.signupError.message.c_str());
  }

  /* Assign the callback function for the long running token generation task */
  config.token_status_callback = tokenStatusCallback; //see addons/TokenHelper.h
  
  Firebase.begin(&config, &auth);
  Firebase.reconnectWiFi(true);
}

void loop(){
  if (Firebase.ready() && signupOK && (millis() - sendDataPrevMillis > 15000 || sendDataPrevMillis == 0)){
    sendDataPrevMillis = millis();
    // Write an Int number on the database path test/int
    if (Firebase.RTDB.setInt(&fbdo, "test/int", count)){
      Serial.println("PASSED");
      Serial.println("PATH: " + fbdo.dataPath());
      Serial.println("TYPE: " + fbdo.dataType());
    }
    else {
      Serial.println("FAILED");
      Serial.println("REASON: " + fbdo.errorReason());
    }
    count++;
    
    // Write an Float number on the database path test/float
    if (Firebase.RTDB.setFloat(&fbdo, "test/float", 0.01 + random(0,100))){
      Serial.println("PASSED");
      Serial.println("PATH: " + fbdo.dataPath());
      Serial.println("TYPE: " + fbdo.dataType());
    }
    else {
      Serial.println("FAILED");
      Serial.println("REASON: " + fbdo.errorReason());
    }
  }
}

and this code from (Wiegand-Protocol-Library-for-Arduino/WiegandTest.ino at master · monkeyboard/Wiegand-Protocol-Library-for-Arduino · GitHub)

#include <Wiegand.h>

WIEGAND wg;

void setup() {
	Serial.begin(9600);  
	
	// default Wiegand Pin 2 and Pin 3 see image on README.md
	// for non UNO board, use wg.begin(pinD0, pinD1) where pinD0 and pinD1 
	// are the pins connected to D0 and D1 of wiegand reader respectively.
	wg.begin();
}

void loop() {
	if(wg.available())
	{
		Serial.print("Wiegand HEX = ");
		Serial.print(wg.getCode(),HEX);
		Serial.print(", DECIMAL = ");
		Serial.print(wg.getCode());
		Serial.print(", Type W");
		Serial.println(wg.getWiegandType());    
	}
}

what I found is, when I call wg.getCode() inside 'Firebase.RTDB.setInt(&fbdo, "test/code", wg.getCode() )'

I tried to do this :

void loop(){

  if (wg.available())
    {
     int x = wg.getCode();
      Serial.print(x); 
     y  = String(x);
  if (Firebase.ready() && signupOK && (millis() - sendDataPrevMillis > 15000 || sendDataPrevMillis == 0)){
    sendDataPrevMillis = millis();}
    // Write an Int number on the database path test/int
     
    
   if (Firebase.RTDB.setString(&fbdo, "test/int", y )){
      Serial.println("PASSED");
      Serial.println("PATH: " + fbdo.dataPath());
     Serial.println("TYPE: " + fbdo.dataType());
    }
    else {
      Serial.println("FAILED");
     Serial.println("REASON: " + fbdo.errorReason()); }}

did not work, I am sorry that I dont share the full script due to several scripts that I have open for testing ,, most sensors worked well ( temprature and gps ..etc) only we Wiegand didnot , from my test I assume the problem resides in the void loop section

becase when I write the previous code like:

 if (Firebase.ready() && signupOK && (millis() - sendDataPrevMillis > 15000 || sendDataPrevMillis == 0)){
    sendDataPrevMillis = millis();

 while(wg.available()){

      if (Firebase.RTDB.setInt(&fbdo, "tags/id", wg.getCode())){
            Serial.println("PASSED");
            Serial.println("PATH: " + fbdo.dataPath());
            Serial.println("TYPE: " + fbdo.dataType());
          }
          else {
            Serial.println("FAILED");
            Serial.println("REASON: " + fbdo.errorReason());
          }
      
    }

it connects to firebase as normal, but does not read from the RFID to the firebase
