Firebase WiFiNINA Library - 'WL_CONNECTED not declared in this scope'

[andyp2000]

I have been following a tutorial to send data to a Firebase database using Arduino.

I am using an Arduino Uno WiFi Rev2, below is the code that simply connects to the WiFi and then sends data to Firebase.

I have previously had success pinging websites with this Arduino using the WiFiNINA library, so assumed that this Firebase WiFiNINA library should work too.

#include <Arduino_LSM6DS3.h>
#include <Firebase_Arduino_WiFiNINA.h>


#define FIREBASE_HOST "compost-app-4a252.firebaseio.com"
#define FIREBASE_AUTH "QKaV81CbgJcnN5zI8mSwpzkoHcWmNIVZyRv1H4dM"
#define WIFI_SSID "VM7923466 2.4GHz"
#define WIFI_PASSWORD "mrRkhbxj5smt"


FirebaseData firebaseData;

String path = "/IMU_LSM6DS3";
String jsonStr;

void setup()
{
  Serial.begin(9600);
  delay(1000);
  Serial.println();

  Serial.print("Initialize IMU sensor…");
  if (!IMU.begin()) {
    Serial.println(" failed!");
    while (1);
  }
  Serial.println(" done");
  Serial.print("Accelerometer sample rate = ");
  Serial.print(IMU.accelerationSampleRate());
  Serial.println(" Hz");

  Serial.print("Connecting to WiFi…");
  int status = WL_IDLE_STATUS;
  while (status != WL_CONNECTED) {
    status = WiFi.begin(WIFI_SSID, WIFI_PASSWORD);
    Serial.print(".");
    delay(300);
  }
  Serial.print(" IP: ");
  Serial.println(WiFi.localIP());
  Serial.println();

  Firebase.begin(FIREBASE_HOST, FIREBASE_AUTH, WIFI_SSID, WIFI_PASSWORD);
  Firebase.reconnectWiFi(true);
}

void loop()
{
  float x, y, z;

  // Read IMU acceleration data
  if (IMU.accelerationAvailable()) {
    IMU.readAcceleration(x, y, z);

    // Send data to Firebase with specific path
    if (Firebase.setFloat(firebaseData, path + "/1-setFloat/X", x)) {
      Serial.println(firebaseData.dataPath() + " = " + x);
    }
    if (Firebase.setFloat(firebaseData, path + "/1-setFloat/Y", y)) {
      Serial.println(firebaseData.dataPath() + " = " + y);
    }
    if (Firebase.setFloat(firebaseData, path + "/1-setFloat/Z", z)) {
      Serial.println(firebaseData.dataPath() + " = " + z);
    }

    // Push data using pushJSON
    jsonStr = "{\"X\":" + String(x,6) + ",\"Y\":" + String(y,6) + ",\"Z\":" + String(z,6) + "}";

    if (Firebase.pushJSON(firebaseData, path + "/2-pushJSON", jsonStr)) {
      Serial.println(firebaseData.dataPath() + " = " + firebaseData.pushName());
    }
    else {
      Serial.println("Error: " + firebaseData.errorReason());
    }

    Serial.println();
    delay(2000);
  }
}

However when I Upload my code, I get the following error: (included the relevant parts)

Arduino: 1.8.16 (Windows 10), Board: "Arduino Uno WiFi Rev2, None (ATMEGA4809)"

...

firebase_test:37:20: error: 'WL_CONNECTED' was not declared in this scope
   while (status != WL_CONNECTED) {

...

firebase_test:43:18: error: 'WiFi' was not declared in this scope
   Serial.println(WiFi.localIP());

...

exit status 1

'WL_IDLE_STATUS' was not declared in this scope

Telling me that a bunch of values and 'WiFi' are not declared in the scope.

• Previously when using the The WiFiNINA library, these values were not declared and just recognised as globals.

• The exact code I am using seems to have been used by others on the same Arduino so I am assuming my issue is something to do with the installed libraries.

Any help is massively appreciated!
