Cant connect to blynk

Please help, i just copy paste from blynk example, and paste the auth token, and run the script, says it works fine, but in the app says my arduino mega havent online :frowning:

#define BLYNK_PRINT Serial1

#include <BlynkSimpleStream.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "e705eab9485d443bba30c60bae5e57a2";

void setup()
  // Debug console

  // Blynk will work through Serial
  // Do not read or write this serial manually in your sketch
  Blynk.begin(Serial, auth);

void loop()
  // You can inject your own code or combine it with other sketches.
  // Check other examples on how to communicate with Blynk. Remember
  // to avoid delay() function!

Is COM7 the correct port for your MCU device?

Are you running an Arduino MEGA or something else with this 2nd hardware Serial1 port? If so, do you have a TTL-USB adapter that you can plug in and run a 2nd terminal program like termite so you can see the debug info?
