On M5Core2 I am not getting a working https request (WiFiClient). What do I wrong?

[Mickey95]

Good day,

The following example for a https request is not working for my M5Core2. I don't see what I am doing wrong.

Has anybody a clue why the example is not working?

Added:

• source and
• Serial log. The last line printed is 'DEBUG 001' followed by 'DEBUG 002'.

#include <WiFi.h>

char ssid[]     = "<SSID_var>";
char password[] = "XXXXX";

char server[] = "www.google.com";
WiFiClient client;

int status = WL_IDLE_STATUS;

void setup() {
  //Initialize serial and wait for port to open:
  Serial.begin(115200);
  delay(1000);
}

void loop() {
  WiFi.begin(ssid, password);

  // Attempt to connect to Wifi network:
  while (WiFi.status() != WL_CONNECTED) {
    Serial.print("Attempting to connect to SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network. Change this line if using open or WEP network:
    delay(1000);
    Serial.print(".");
  }

  Serial.println("Connected to wifi");
  printWifiStatus();
  Serial.println("\nStarting connection to server...");

  // if you get a connection, report back via serial:
  if (client.connect(server, 443)) {
    Serial.println("connected to server");
    // Make a HTTP request:
    client.println("GET /search?q=arduino HTTP/1.1");
    client.println("Host: www.google.com");
    client.println("Connection: close");
    client.println();
    Serial.println("DEBUG 001");
  }
  Serial.println("DEBUG 002");
  
  // if there are incoming bytes available
  // from the server, read them and print them:
  while (client.available()) {
    char c = client.read();
    Serial.write(c);
  }

  // if the server's disconnected, stop the client:
  if (!client.connected()) {
    Serial.println();
    Serial.println("disconnecting from server.");
    client.stop();
  }
  // do nothing forevermore:
  while (true);
}

void printWifiStatus() {
  // print the SSID of the network you're attached to:
  Serial.print("SSID: ");
  Serial.println(WiFi.SSID());
  // print your WiFi shield's IP address:
  IPAddress ip = WiFi.localIP();
  Serial.print("IP Address: ");
  Serial.println(ip);
  // print the received signal strength:
  long rssi = WiFi.RSSI();
  Serial.print("signal strength (RSSI): ");
  Serial.print(rssi);
  Serial.println(" dBm");
}

Hello @Mickey95

I don't think WiFiClient can handle HTTPS requests. I think you need to use WiFiClientSecure for that.

Thanks

@felmue Thank you for the answer. This is working! Meanwhile my own example is working using an updated PEM certificate :-)

Can we see the code?

@felmue Thank you for the answer. This is working! Meanwhile my own example is working using an updated PEM certificate :-)

So It was the PEM certificate that was the cause?
How did you discover that?

@mickey95 dude?
