Lesson 3 Connect your device to QIoT Suite Lite using MQTTS

In Lesson 2 , we complete deploy sample code to your device .In this lesson, you will learn how yo use sample code to connect to QIoT Suite Lite.

And there are two parts：

A: Run Sample Code

B:Another protocol

Part A :Run Sample Code

• Open Terminal application (e.g., PuTTY) on your PC.Connect to your device by SSH and enter the folder where put sample code (e.g., /home/root/bundle).
  

• Install sample code dependency,enter command as following
  
  

  root@edison_arduino:~# cd {folder where you put sample code}
  
  root@edison_arduino:~/bundle# npm install

  
  


• Run sample code
  
  

  root@edison_arduino:~/bundle# node mqtt.js
  
  

  
  


• device will send message to topic "temp" or that you defined ,as below image.
  

Part B :Another protocol

• Click "Connection a device" button
  


• You can choose another protocol you would like to use

• SSH to your device , and input command as following.
  
  

  pi@berry:~/bundle$ cd /home/{{user}}/bundle
  
  
  
  // mqtt(dont' need certificate,just put JSON file to "res" folder):
  
  root@edison_arduino:~/bundle# node mqtt.js
  
  
  
  // http
  
  root@edison_arduino:~/bundle# node http.js
  
  
  
  // https
  
  root@edison_arduino:~/bundle# node https.js
  
  
  
  // coap
  
  root@edison_arduino:~/bundle# node coap.js

  
  


• In next Lesson ,we will integrate Power BI to visualize senser data . Lesson 4 Integrate Power BI
