Low Energy Bluetooth Service

This is a service that allows your widget to link to the devices bluetooth signal and paired devices. This is very useful when developing for IoT (Internet of Things)

Note: this will not work on the control side of your plugin

buildfire.services.bluetooth.ble (bluetooth low energy)

Used on the Widget side communicate with paired bluetooth devices

Requirements

• From the Widget

<script src="../../../scripts/buildfire/services/bluetooth/ble.js"></script>

• in plugin.json add bluetooth in your feature array "features" : ["bluetooth"]

Example

https://github.com/BuildFire/bluetoothExamplePlugin

Constructor

none. ble is a singleton

Methods

• connect (deviceId,callback) : use this method to connect to the device
  • deviceId: the device Id you received from the paired device list
  • callback (err,data): callback function called when connected or failed to connect.
• disconnect function (callback) : used to disconnect from the previously connected device
  • callback (err,data): callback function called when the disconnect occurs or fails.
• listPairedDevices function(callback): Get a list of paired bluetooth devices
  • callback(err,devices): a callback function the is called an array of devices.
    • devices: an array of devices with two properties
      • deviceId: string
      • name: string
• write function (data, callback): Used to send string data to the device
• available function (callback): check if device is available
• read function (callback):reads the buffer from the bluetooth
• readUntil function (terminator,callback): reads from the buffer until the terminator is found. for example if the terminator equals , it will continue to read until it finds the next comma
• subscribe function (delimiter,callback): will automatically send you the buffer when the terminator if found
• unsubscribe function (callback): stop subscribing
• clear function (callback) clears the buffer
