GoDice JavaScript API (with demo)

Overview

Use the GoDice JavaScript API to integrate GoDice functionality into your own JavaScript applications.

Here are some of the things that you can do with the GoDice JavaScript API:

Turn ON/OFF GoDice RGB Leds
Ask for the die Color (dots color)
Ask for the die battery level
Get differernt notifications reagrding the die state (Rolling or Stable and get the outcome number)
Use and configure different shells

To run the demo (that use the API) just open the index.html file in Chrome or Microsoft Edge browser

Getting Started

Create a web page and include the GoDice JavaScript API file (godice.js):
<script src="godice.js"></script>
In your main JavaScript file create a new instance of the GoDice class: goDice = new GoDice();
To open the Bluetooth connection dialog and connect to your GoDice, call the following funtion: goDice.requestDevice();
After successfull connection the function onDiceConnected will be called from the GoDice class

API Functions

There are few types of API calls:

Message - a message to the die
Request - a message to the die, that should follow by corresponding response.
Response - an event that is expected after sending the request
Events - a message sent by the die

Once you followed the "Getting Started" section and you have the goDice instance ready you can call to the following class functions:

Message:

/**
 * Turn On/Off RGB LEDs (the LEDs will turn off if both led1 and led2 are null or set to [0,0,0])
 * @param {Array} led1 - an array to control the 1st LED in the following format '[R,G,B]'
 *                       where R,G and B are numbers in the range of 0-255
 * @param {Array} led2 - an array to control the 2nd LED in the following format '[R,G,B]'
 *                       where R,G and B are numbers in the range of 0-255
 */                          
 setLed(led1, led2);

/**
 * Pulses LEDs for a defined time and color
 * @param {number} pulseCount - an integer of how many times the pulse will repeat (max 255)
 * @param {number} onTime - how much time should the LED be ON each pulse (units of 10ms, max 255) 
 * @param {number} offTime - how much time should the LED be OFF each pulse (units of 10ms, max 255)
 * @param {Array}  RGB - an array to control both LEDs color's in the following format '[R, G, B]' 
 *                 where R, G and B are number in the range of 0-255
 */
 pulseLed(pulseCount, onTime, offTime, RGB)

Requests:

 /**
  * Open a browser connection dialog to connect a single GoDice, after successfull connection it will followed 
  * by corresponding "onDiceConnected" callback function (response) from the GoDice class (instance).
  */	
  requestDevice();

 /**
  * Request for the die color, that should follow by corresponding "onDiceColor" callback function (response) 
  * from the GoDice class (instance).
  */
  getDiceColor(){

 /**
  * Request for the die battery, that should follow by corresponding "onBatteryLevel" callback function (response)
  * from the GoDice class (instance).
  */
  getBatteryLevel()

  /**
  * Sets the die type for the die value calculations, Use GoDice.diceTypes.X for die type.
  * Supported dice types (Shells): D6, D20, D10, D10X, D4, D8, D12
  * Default die type is D6 (when not calling this function)
  * @param {ENUM} GoDice.diceTypes - the die type
  */
  setDieType(GoDice.diceTypes)

Responses:

 /**
