ng-cordova-bluetoothle

This wraps the Bluetooth Low Energy Phonegap Plugin by Rand Dusing in AngularJS code so it can be used more easily in AngularJS mobile applications.

Using ngCordovaBluetoothLE In Your Project

The core Apache Cordova plugin is required to use this wrapper:

cordova plugin add https://github.com/randdusing/BluetoothLE

Example Usage

Scanning all BLE devices in range

var params = {
  request: true,
  time : 10000 //in milliseconds, time to scan defaults to 5000ms if not provided
};
$cordovaBluetoothle.startScan(params).then(function(success) {
	console.log(device.name);
	console.log(device.address);
});

The Scan method will stop as soon as it finds its first device. This is probably not what you want; and is a limitation of wrapping a continuous operation (like scan) into a one-time promise resolution. This is definitely open for improvement. I use 'find' instead to find a specific device.

Scanning for Specific Device using .find()

var params = {
  request: true, //ask user to enable bluetooth
  name: 'Jewelbot' //device name to look for
};


$ionicPlatform.ready()
        .then(function () {
          return $cordovaBluetoothle.initialize(params)
            .then(function () {
              //successfully initialized
              return $cordovaBluetoothle.find(params);
            }, function (err) {
              //error trying to initialiez
            });
        })
        .then(function (data) {
          // Scanning for specific device
          if (data.status === 'scanResult') {
            $scope.model.status = 'Found device: ' + data.name;
            $scope.model.devices.push(data);
            return $cordovaBluetoothle.stopScan();
          }
        }, function (error) {
          $scope.model.status = 'Error while scanning.' + JSON.stringify(error);
          return $cordovaBluetoothle.stopScan();
        }, function (notify) {
          // found other devices; but not the device you're looking
        })
        .then(function () {
          $scope.model.status = 'ending scan...';
          return $cordovaBluetoothle.isScanning().then(function(isScanning) {
            $scope.model.status = isScanning ? 'Scan Not Ended' : 'Scan Ended';
            if (isScanning) {
              return $cordovaBluetoothle.stopScan();
            }
          });
        });

Pairing (assumes address found during scan)

.controller("ExampleController", ['$cordovaBluetoothle', '$ionicPlatform', '$scope', function($cordovaBluetoothle,$ionicPlatform, $scope ) {
    
    $ionicPlatform.ready()
          .then(function () {
            return $cordovaBluetoothle.connect({address: $scope.model.address})
              .then( function (success) {
                //successfully paired
              })
              .error(function (err) {
                //error while pairing, return promise that invokes disconnect.
                return $cordovaBluetoothle.disconnect(address);
              })
              .notify(function (notify) {
                //still trying to connect. 
              });
          });
