Arduino R4 wifi sketch is not compiling

[JohnLincoln]

I've had some limited success.

I went to my Arduino Cloud Sketches at https://app.arduino.cc/sketches

There I found that 2 new sketches had appeared: Weather_Report_aug21a and Weather_Report_aug21b

Weather_Report_aug21b had 3 tabs:
Weather_Report_aug21b.ino, thingProperties.h and Sketch Secrets.

Weather_Report_aug21a only had 2 tabs. Sketch Secrets was missing.
So I concentrated on Weather_Report_aug21b.

When I inspected 'Sketch Secrets' it did not look like the 'Sketch Secrets' that I had seen in other working sketches.

This is what it should have have looked like:

I clicked on the 'ADD NEW' button and manually entered the correct details:

I'll delete the erroneous entry later on.

When I tried to compile the code, there were errors.

Unfortunately I don't have a screenshot with the errors on, or the error message itself.

Here is the code that was created:

Weather_Report_aug21b.ino

#include "arduino_secrets.h"
#include <WiFiS3.h>
#include <ArduinoJson.h>
#include <ArduinoHttpClient.h>
#include "thingProperties.h"
#include <Arduino_LED_Matrix.h>
#include <Arduino_CloudConnectionFeedback.h>

ArduinoLEDMatrix matrix;

// Number that sets how many days of forecasts that are collected
const int numOfForecasts = 7;

double temperatureMax[numOfForecasts];
double temperatureMin[numOfForecasts];
int weather[numOfForecasts];


void setup() {
  Serial.begin(9600);
  delay(1500);

  matrix.begin();

  // Defined in thingProperties.h
  initProperties();

  // Connect to Arduino Cloud
  ArduinoCloud.begin(ArduinoIoTPreferredConnection);
  waitForArduinoCloudConnection(matrix);

  ArduinoCloud.printDebugInfo();

  int status = WL_IDLE_STATUS;
  WiFi.begin(SSID, PASS);
  delay(1000);
  status = WiFi.status();

  // Set location of weather forecasts
  //and display location on the cloud dashboard
  weatherLocation = Location(latitude, longitude);

  getWeatherData();
}

void loop() {
  ArduinoCloud.update();
}

void getWeatherData() {
  int httpPort = 80;
  char serverAddress[] = "api.open-meteo.com"; // server address
  WiFiClient wifi;
  HttpClient client = HttpClient(wifi, serverAddress, httpPort);

  // This loop will look through the JSON response and find the lines
  // that contain the temperature and weather codes,
  // which will then be placed in arrays so they can be easily accessed
  client.get("/v1/forecast?latitude=" + String(latitude) + "&longitude=" + String(longitude) + "&current=temperature_2m,weather_code&daily=weather_code,temperature_2m_max,temperature_2m_min&timezone=Europe%2FBerlin");

  unsigned long timeout = millis();
  while (client.available() == 0) {
    if (millis() - timeout > 5000) {
      client.stop();
      return;
    }
  }

  int statusCode = client.responseStatusCode();
  // The entire response from the API in JSON is then stored in "result"
  String result = client.responseBody();
  // To only get the information that is needed, the JSON response will be parsed using a parsing function
  parseWeatherData(result);
}

void parseWeatherData(const String& json) {
  StaticJsonDocument<7000> doc;
  deserializeJson(doc, json);

  // This loop will look through the JSON response and find the lines
  // that contain the temperature and weather codes,
  // which will then be placed in arrays so they can be easily accessed
  for (int i = 0; i < numOfForecasts; i++) {
    temperatureMax[i] = doc["daily"]["temperature_2m_max"][i];
    temperatureMin[i] = doc["daily"]["temperature_2m_min"][i];
    weather[i] = doc["daily"]["weather_code"][i];
  }
}

  weatherLocation = Location(latitude, longitude);

}

  ArduinoCloud.addProperty(weatherLocation, READ, ON_CHANGE, NULL);
  ArduinoCloud.addProperty(forecastSchedule, READWRITE, ON_CHANGE, onForecastScheduleChange);

}

WiFiConnectionHandler ArduinoIoTPreferredConnection(SSID, PASS);

Sketch Secrets

#define SECRET_moto_e_13_ ""

// this is the erroneous arduino_secrets.h 
// as generated by the Arduino Cloud.

The errors were due to void onLatitudeChange() and void onLongitudeChange() in the .ino file being defined twice.

I commented out the second definition and retried the compiling.

Success at last:

Now I have the following Dashboard:

I've got a nice new dashboard, but it does not get populated with any data.

I don't know whether the errors that the Arduino Cloud introduced were peculiar to me , or whether @d2v5d will have exactly the same faults.

@mario-r , I don't think that someone new to Arduino would stand any chance of finding the errors that i did.
