[SOLVED] EPOCH TIME with ESP Board Manager v.3.0.1

Projects Programming
1

Hi,
Do you guys know which version of this library: GitHub - arduino-libraries/NTPClient: Connect to a NTP server or any other library that works fine with the ESP board manager v.3.0.1 obtaining the Epoch time?
I use the function .getEpochTime(), assign the output value to an unsigned long variable and then cast it as a String and it does only return a string of 4 digits as the code below:

unsigned long now = timeClient.getEpochTime();
json.add("timestamp", (String)now);

Get Epoch/Unix Time with the ESP32 (Arduino) | Random Nerd Tutorials.

Followed their tutorial using the ESP8266. It doesn't work

4

This will work both with ESP32 and ESP8266

Yea, an ESP8266 and a ESP32 are different animals. Sorry for posting the wrong link.

I'm using Firebase Arduino Client Library for ESP8266 and ESP32 v.2.3.7 and the ESP board manager v.3.0.1
Can I ask you if you can help me putting this code (I use an ESP01) into this one:
Thx in advance

#include <WiFi.h>
#elif defined(ESP8266)

    delay(300);
  }
  /*.println();
    Serial.print("Connected with IP: ");
    Serial.println(WiFi.localIP());

  //Or use legacy authenticate method

  Firebase.begin(&config, &auth);

  Firebase.reconnectWiFi(true);

  timeClient.begin();
}

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

    bool Sr = false;

    while (Serial.available())
    {

    delay(1000);

    if (Sr == true)
    {

      //get comma indexes from values variable
      int fristCommaIndex = values.indexOf(',');
      int secondCommaIndex = values.indexOf(',', fristCommaIndex + 1);

      int fourthCommaIndex = values.indexOf(',', thirdCommaIndex + 1);
      int fifthCommaIndex = values.indexOf(',', fourthCommaIndex + 1);

      Firebase.RTDB.setString(&fbdo, "/test/real/temp", values.substring(0, fristCommaIndex));
      Firebase.RTDB.setString(&fbdo, "/test/real/hum", values.substring(fristCommaIndex + 1, secondCommaIndex));

      Firebase.RTDB.setString(&fbdo, "/test/real/alt", values.substring(thirdCommaIndex + 1, fourthCommaIndex));
      Firebase.RTDB.setString(&fbdo, "/test/real/lum", values.substring(fourthCommaIndex + 1));

      if (count == 31)
      {
        FirebaseJson json;
        json.add("temp", values.substring(0, fristCommaIndex));

        // Space to provide EPOCH TIME
        
        json.add("timestamp", epochTime);

        Firebase.RTDB.pushJSON(&fbdo, "/test/data", &json);
        Firebase.RTDB.updateNode(&fbdo, String("/test/data/" + fbdo.pushName()).c_str(), &json);
        count = 0;
      }
      count++;
    }
  }

}

Solved by updating the firebase-esp-client library to its latest version: 4.0.0
Where there is a proper function to get timestamp ad a double variable and then pushing it as a value in the json.
