Need help adding usb Dongle to Blynk using a Arduino Mega adk

Here is possibly an easier example to start with for the Mega…

//#define BLYNK_DEBUG   // Advanced diagnostic data... also drastically slows entire sketch
#define BLYNK_PRINT Serial  // This prints to Serial Monitor
#define BLYNK_USE_128_VPINS
#include <ESP8266_Lib.h>  // ESP-01 Link
#include <BlynkSimpleShieldEsp8266.h>  // ESP-01 Link

ESP8266 wifi(&Serial1);  // Pins 18 & 19 on MEGA - For ESP-01 link
BlynkTimer timer;

#define HTB 13  // Set HeartBeat LED pin.

char auth[] = "xxxxxxxxxx";
char ssid[] = "xxxxxxxxxx";
char pass[] = "xxxxxxxxxx";
char server[] = "blynk-cloud.com";
int port = 8080;



void setup() {
  pinMode(HTB, OUTPUT);
  Serial.begin(115200);  // BLYNK_PRINT data - For Serial Monitor
  Serial1.begin(115200);  // Set baud rate - For ESP-01 link
  wifi.setDHCP(1, 1, 1); //Enable dhcp in station mode and save in flash of esp8266
  Blynk.config(wifi, auth, server, port);
  if (Blynk.connectWiFi(ssid, pass)) {
    Blynk.connect();
  }

  // Timed Lambda Function - UpTime counter
  timer.setInterval(1000L, []() {  // Run every second
    Blynk.virtualWrite(V0, millis() / 1000);  // Display the UpTime in Seconds to Widget on V0
  });  // END Lambda Function
}



void loop() {
  timer.run();
  Blynk.run();
}
