4Duino - Blynk compiling probleme

hello,

i would like to use my 4Duino with Blynk, but when I trying to compile the sketch, it gives me an error:
This code is intended to run on the ESP8266 platform! Please check your Tools->Board setting.

#include <ESP8266WiFi.h>
#include <BlynkSimpleEsp8266.h>

char auth = “dc757563b77349718e1678b3ce46230f”;
char ssid = “TPLINK_SRV”;
char pass = “medicor2017”;

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

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

Correct… But in your case it appears you are running an Arduino with an ESP as shield… possibly similar to this setup

Perhaps try this instead (adjust for proper pin connections between Arduino and ESP).
