Story

First, you have to configure the LinkIt as Station Mode, for this see my previous project:

https://www.hackster.io/LaurenceHR/getting-started-with-station-mode-of-linkit-smart-7688-duo-34c0f0

STEP 1: Connect to LinkIt Console with a USB to TTL adapter

To use the LinkIt Duo as like a Arduino Yun, you have to enable Bridge Feature. For this you have to run a script, but you have to connect for COM shell (in this case I use Putty).

1 / 2 • RX -> Pin 8 & TX -> Pin 9

STEP 2: Enable Bridge

thanks for read, don't forget respect ;)

If you create this too, share your project ;)

Code

#define CAYENNE_DEBUG         // Uncomment to show debug messages
#define CAYENNE_PRINT Serial  // Comment this out to disable prints and save space
#include <BridgeClient.h>
#include <CayenneYun.h>

char token[] = "o4ygx08hpx";

// Custom Widget
#define VIRTUAL_PIN 1
#define LED_DIGITAL_PIN 12

void setup(){
  pinMode(LED_DIGITAL_PIN, OUTPUT);
  Serial.begin(9600);
  Cayenne.begin(token);  
}

CAYENNE_IN(VIRTUAL_PIN){  
  int currentValue = getValue.asInt(); // 0 to 1  
  if (currentValue == 1) { 
    digitalWrite(LED_DIGITAL_PIN, HIGH);
  } else { 
    digitalWrite(LED_DIGITAL_PIN, LOW);
  }
}

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