Linux command line bluetoothctl wrapper for nodejs

powerful command line utulity bluetoothctl for discovery, connect,disconnect, scan, pair etc.. if you want to connect bluetooth speakers , mouse, keyboard etc.. you can use this module. you must install bluetoothctl . for raspberry pi 3 , it comes as default with raspbian. example install process: sudo apt-get install bluez blueman alsa-utils bluez-alsa

Features:

• checkBluetoothController() : checks if bluetooth controler exists or not

• getPairedDevices() : checks already paired devices.

• getDevicesFromController() : checks already scanned devices.

• disconnect(macID) : disconnect from macID

• info(macID) : checks features of device with given macID

• pair(macID) : pairs with given macID

• confirmPassKey(bool) : confirms passkey while paring.

• scan(bool) : starts or stops scanning of bluetooth devices. while scan is set true, current audio playback might get crackling.. so stop scan after you found what you are searching.

• discoverable(bool) : sets your raspberry or linux device's bluetooth as discoverable.

• isScanning : checks if bluetoothctl is already scanning. returns true/false

• isBluetoothReady : checks if our bluetooth controller ready.returns true/false

• isBluetoothControlExists : checks if we have a bluetooth hardware or not.

• devices : returns the scanned and found devices as array. example output at below..

• controllers : returns the found bluetooth hardware devices.

Events

• Controller: event fires when bluetooth controller detected from system

• DeviceSignalLevel: event fires when a discoverable bluetooth device's signal level detected.

• Device: event fires when a new device found or a device sends its features

• PassKey: event fires when passkey confirmation is required to pair device. confirmPasskey(true) should be called in response to this event.

Basic usage

 var blue = require("bluetoothctl");
 blue.Bluetooth()
 
 
 blue.on(blue.bluetoothEvents.Controller, function(controllers){
 console.log('Controllers:' + JSON.stringify(controllers,null,2))
 });
 
 
 blue.on(blue.bluetoothEvents.DeviceSignalLevel, function(devices,mac,signal){
     console.log('signal level of:' + mac + ' - ' + signal)
 
 });
 
 blue.on(blue.bluetoothEvents.Device, function (devices) {
     console.log('devices:' + JSON.stringify(devices,null,2))
 })
 
 blue.on(blue.bluetoothEvents.PassKey, function (passkey) {
     console.log('Confirm passkey:' + passkey)
     blue.confirmPassKey(true);
 })
 
 var hasBluetooth=blue.checkBluetoothController();
 console.log('system has bluetooth controller:' + hasBluetooth)
 
 if(hasBluetooth) {
     console.log('isBluetooth Ready:' + blue.isBluetoothReady)
     blue.scan(true)
     setTimeout(function(){
         console.log('stopping scan')
         blue.scan(false)
         blue.info('00:0C:8A:8C:D3:71')
     },20000)
 }

  {
    "mac": "B8:27:EB:2E:66:7B",
    "name": "raspberrypi"
  }
]

Sample output of devices:

devices:[
  {
    "mac": "00:0C:8A:8C:D3:71",
