Dummy_Device_IoTtalk_v2_Javascript

This is a DA example in Javascript version, which has enabled automatic IDF push/ODF pull.

Quick Start

Modify apiUrl in option

apiUrl: 'http://IP:9992'

Open index.html in your browser

file://file-path-to-index.html

After you bind the DA in your IotTalk project, it will send and receive the data automatically.

If you want to modify it into your own program, you only need to modify sa.js

API Reference

class iottalkjs.DAI

constructor iottalkjs.DAI(option)

options is an object:

• apiUrl (string): The CSM API URL.
• deviceModel (string)
• deviceName (string)
• deviceAddr (string): Should be a valid UUID string.
• persistentBinding (bool): Default is false.
• username (string): The DA owner.
• extraSetupWebpage (string)
• deviceWebpage (string)
• onRegister (function): A callback function with signature function (dan). The first argument is the instance of iottalkjs.DAN.Client.
• onDeregister (function): A callback function with signature function (dan).
• onConnect (function): A callback invoked on MQTT broker connected. The signature is function (dan).
• onDisconnect (function): A callback function with signature function (dan).
• pushInterval (number): The push interval in second.
• interval (object): The key is the device feature name in string.
• idfList (Array): Should be a list of idf, unit pairs. Where a idf, unit pair can be following format:
  • [<function pointer>, <unit>]: e.g.: [Dummy_Sensor, ['dB']]
  • [<df name>, <unit>]: In this case, since the function pointer is not provided, the auto-push won't be applied. Please checkout the Smartphone example.
• odfList (Array)

Example:

const Dummy_Sensor  = () => { ... };
const Dummy_Control = () => { ... };

const da = new iottalkjs.DAI({
  apiUrl: 'http://IP:9992',
  deviceModel: 'Dummy_Device',
  deviceName: 'MyMagicDevice',
  deviceAddr: '0a14943f-cc88-4f36-a441-dc3f42f03546',
  persistentBinding: true,
  idfList: [[Dummy_Sensor, ['dB']]],
  odfList: [[Dummy_Control, ['dB']]],
});

Example of DF name conversion, the valid underscore suffix (_) in function name will be converted to df naming rules (-):

const Acceleration_I = () => { ... };

const da = new iottalkjs.DAI({
 ...
 idfList: [Acceleration_I, ['g']],
 inverval: {
   'Acceleration-I': 42,
 },
});

run()

const da = new iottalkjs.DAI({ ... });
da.run();
