Как сделать GET HTTP-запрос от Arduino на Firebase?

У меня есть Arduino UNO и SIM808, и я пытаюсь отправить свои данные GPS на базу огня. Я успешно создал веб-сайт, на котором я могу размещать данные с веб-сайта в Firebase. Однако я пытаюсь отправить свои данные с Arduino на веб-сайт, который постоянно терпел неудачу. Я понятия не имею, в чем ошибка.

Вот мои коды:

  /*
    ### Get GPS data
    1. This example is used to test SIM808 GPS/GPRS/GSM Shield's reading GPS data.
    2. Open the SIM808_GetGPS example or copy these code to your project
    3. Download and dial the function switch to Arduino
    4. open serial helper
    4. Place it outside, waiting for a few minutes and then it will send GPS data to serial

Я продолжаю получать ошибку 603.

Ниже приведены мои коды PHP, веб-сайта для firebase:

    <?php
require_once 'firebaseLib.php';
// --- This is your Firebase URL
$url = 'https://projectname-default-rtdb.asia-southeast1.firebasedatabase.app/';
// --- Use your token from Firebase here
$token = 'XXXXXXXXXXJYszyqIJxr3UuGl1Zr6qHG03K';
// --- Here is your parameter from the http GET
$arduino_data = $_GET['arduino_data'];
// --- Set up your Firebase url structure here
$firebasePath = '/GPSdata';

/// --- Making calls
$fb = new fireBase($url, $token);
$response = $fb->set($firebasePath, $arduino_data);
echo $url;
sleep(2);

ОБНОВЛЕНИЕ:

Я могу получить код 200, но в моей базе данных или на моем сайте нет никаких результатов.
