Cylon.js (http://cylonjs.com) is a JavaScript framework for robotics, physical computing, and the Internet of Things using Node.js
This repository contains the Cylon adaptor/drivers to connect to Bluetooth Low Energy (LE) peripherals. It uses the Noble node module (https://github.com/sandeepmistry/noble) created by @sandeepmistry thank you!
For more information about Cylon, check out the repo at https://github.com/hybridgroup/cylon
Install the module with:
$ npm install cylon cylon-ble
For Ubuntu you must install the following dependency prior to npm install cylon-ble:
$ sudo apt-get install libbluetooth-dev
Here's a basic BLE example to get the battery level of a device:
"use strict";
var Cylon = require('cylon');
Cylon.robot({
connections: {
bluetooth: { adaptor: 'ble', uuid: '207377654321' }
},
devices: {
battery: { driver: 'ble-battery-service' }
},
work: function(my) {
my.battery.getBatteryLevel(function(err, data) {
if (!!err) {
console.log("Error: ", err);
return;
}
console.log("Data: ", data);
});
}
}).start();var Cylon = require('cylon');
Cylon.robot({
connections: {
wiced: { adaptor: 'ble', uuid: '207377654321' }
},
devices: {
battery: { driver: 'ble-battery-service' }
},
work: function(my) {
every((1).second(), function() {
my.battery.getBatteryLevel(function(err, data){
if (err) {
console.log(err);
} else {
console.log("BatteryLevel:", data);
}
});
});
}
}).start();You will need a computer with a hardware adaptor that supports Bluetooth LE, also known as Bluetooth 4.0, or Bluetooth Smart. Also, this module currently only supports OSX and Linux operating systems.
You can use the cylon-ble modules's included commands to scan for BLE devices, and then to list the various BLE characteristics for a specific device.
Note that you need to install cylon-ble using the -g option, and then run each commands under sudo like this:
$ sudo cylon-ble-scan
Starting scan.
