PubSubClient : mqtt_auth

Hi,

ESP32-Mqtt was not connected using Azure SSL Certificate

I am using the below code for connecting with ssl certificate was not working.

#include <wificlientsecure.h>
const char* ssid = "xxx"; // your network SSID (name of wifi network)
const char* password = "xxx"; // your network password
const char* server = "xxx.azure-devices.net"; // Server URL
const char* test_root_ca=
"-----BEGIN CERTIFICATE-----\n"

"-----END CERTIFICATE-----\n";

// You can use x.509 client certificates if you want
const char* test_client_key =
"-----BEGIN RSA PRIVATE KEY-----\n"

"-----END RSA PRIVATE KEY-----\n"; //to verify the client

const char* test_client_cert =
"-----BEGIN CERTIFICATE-----\n"

"-----END CERTIFICATE-----\n"; //to verify the client
WiFiClientSecure client;
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(115200);
delay(100);
Serial.print("Attempting to connect to SSID: ");
Serial.println(ssid);
WiFi.begin(ssid, password);
// attempt to connect to Wifi network:
while (WiFi.status() != WL_CONNECTED) {
Serial.print(".");
// wait 1 second for re-trying
delay(1000);
}
Serial.print("Connected to ");
Serial.println(ssid);
client.setCACert(test_root_ca);
client.setCertificate(test_client_cert); // for client verification
client.setPrivateKey(test_client_key); // for client verification
Serial.println("\nStarting connection to server...");
if (!client.connect(server, 8883)){
Serial.println("Connection failed!");
}
else {
Serial.println("Connected to server!");
}
}
void loop() {
// do nothing
}

This example was tested on 2016-06-11 and it compiles on Arduino Uno, Arduino Leonardo, Arduino Mega.
