Does Arduino OPTA WiFi have WiFi Secure library of any sort?

Does any of you experienced Arduino professionals have any idea about how to use the Arduino OPTA WiFi connecting via HTTPS to a site?

All examples I have found use port 80, and I have not been able to find out if there is a library (ie. I have tried WiFiNINA without success) for making HTTPS connections (with TLS/SSL).

It is not because of that I want the HTTPS. It is because of that the server we are using have stopped offering HTTP on port 80. We get an error 301 - when trying to access the http://domain.com/opta.php file, we are told that it has moved to https://domain.com/opta.php - in effect meaning that the http on port 80 is unavailable.

So, we would indeed need a port 443 based WiFi library for the Arduino OPTA WiFi model.

My code looks like this here:

#include <WiFi.h>
#include <WiFiClient.h>  // For HTTPS connections


const char* ssid = "xxxx";          // Your WiFi network name
const char* password = "xxxx";  // Your WiFi network password
const char* serverHost = "xxxxxx.xxxxxx";  // Your server's host URL (without http:// or https://)
const int serverPort = 443;               // Server port (usually 80 for HTTP)
const String postPath = "/xxxx.php";          // The API endpoint path

void setup() {
  Serial.begin(115200);
  delay(1000);
  digitalWrite(LED_D0, HIGH);
  delay(1000);
  digitalWrite(LED_D0, LOW);

  // Connect to WiFi
  WiFi.begin(ssid, password);
  Serial.print("Connecting to WiFi...");
  
  while (WiFi.status() != WL_CONNECTED) {
    delay(500);
    Serial.print(".");
  }
  
  Serial.println("\nConnected to WiFi!");
}

void sendPostRequest() {
  WiFiClient client;
  // client.setInsecure();  // Bypass certificate verification for testing

  // Connect to the server with HTTPS
  if (!client.connect(serverHost, serverPort)) {
    Serial.println("Connection to server failed!");
    return;
  }
  
  Serial.println("Connected to server");

  // Manually create the JSON string
  String jsonPayload = "{\"Command\":\"Cadence\"}";

  // Construct HTTPS POST request
  client.println("POST " + postPath + " HTTP/1.1");
  client.println("Host: " + String(serverHost));
  client.println("Content-Type: application/json");
  client.println("Connection: close");
  client.print("Content-Length: ");
  client.println(jsonPayload.length());
  client.println();
  client.println(jsonPayload);  // Send JSON payload

  // Wait for a response from the server
  while (!client.available()) {
    delay(10);
  }

  // Read and display the response
  String response = client.readString();
  Serial.println("Response:");
  Serial.println(response);

  // Parse the JSON response manually
  parseResponse(response);

  // Close the connection
  client.stop();
}

void parseResponse(String response) {
  int statusIndex = response.indexOf("\"Status\":\"");
  int statusEnd = response.indexOf("\"", statusIndex + 10);
  String statusValue = response.substring(statusIndex + 9, statusEnd);

  int codeIndex = response.indexOf("\"Code\":");
  int codeEnd = response.indexOf(",", codeIndex);
  String codeValue = response.substring(codeIndex + 7, codeEnd);

  int messageIndex = response.indexOf("\"Message\":\"");
  int messageEnd = response.indexOf("\"", messageIndex + 11);
  String messageValue = response.substring(messageIndex + 10, messageEnd);

  Serial.println("Parsed JSON response:");
  Serial.println("Status: " + statusValue);
  Serial.println("Code: " + codeValue);
  Serial.println("Message: " + messageValue);
}

void loop() {
  sendPostRequest();
  delay(10000);  // Send the request every 10 seconds
}

It looks like you did specify 443.
