Robotdyn atmega2560+esp8266 connection via wifi using blynk app

Need Help With My Project
1

Hello dear, im using a very rare arduino board called Atmega2560+ESP8266 ,It’s a single board with built in espr8266 , i’m trying to connect it with blynk app via internet like when we do it for single ship ex. esp8266 ( i tried ESP_STANDALONE) example for my another ship (ESP8266) ,

LET BACK TO MY ATMega5260+ESP8266 i got a connection to blynk app it tell me that ur device is online ( selected ATmega2560 hardware to my project , but the problem that i cant see any output changes on the pins

#define BLYNK_PRINT Serial    // Comment this out to disable prints and save space
#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

// You should get Auth Token in the Blynk App.
// Go to the Project Settings (nut icon).
char auth[] = "f798cd6dba894b96a5f55de9233f282c";

// Your WiFi credentials.
// Set password to "" for open networks.
char ssid[] = "Bezeq";
char pass[] = "18121993";

void setup()
{
  Serial.begin(9600);
  Blynk.begin(auth, ssid, pass);
}

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

this is uploded to the board when it’s selected to work as esp8266

and this when selected as atmega , u have to know that the hardware is selected to be ATmega8266
and it gave me online , but i tried to control relay or even led i didn’t see any changes

thanks for ur correction
bare in mind that the board have a dip switch which change the mode of it’s operation (USB>ESP)(USB>MCU) (MUC>ESP)

thus for when acting ATmega2560

Please format your code correctly before anymore support can be provided.

```cpp

i have already operated the board with Aurduino_wifi example, and then it gave me that it’s online , i just now i need a code or a modification to my code to see the change in o/p pins

Code snippets should be formatted. Please edit your initial post:

How to do that:

?format=2500w960×540 


 ``` cpp <--put 3 backticks BEFORE your code starts  ("cpp" means C++ language) 

   //Put your code here
   //..................
   //..................

 ``` <--insert 3 backticks AFTER your code

**This makes your code readable and with highlighted syntax, like this

↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓↓

//comment goes here 
void helloWorld() { 
   String message =  "hello" + "world"; 
}

also post your serial monitor output
