title: ble trouble with IONIC 2
body: <p>I am creating an app with ionic 2 and am trying to work with the <a href="https://github.com/don/cordova-plugin-ble-central" rel="nofollow"><code>ble-plugin</code></a>. I ran the installation:</p>
  
  <pre><code>$ cordova plugin add cordova-plugin-ble-central
  </code></pre>
  
  <p>then wrote the following in my page's TS:</p>
  
  <p>import {Page, Alert, NavController} from 'ionic-angular';</p>
  
  <pre><code>@Page({
    templateUrl: 'build/pages/hello-ionic/hello-ionic.html'
  })
  
  export class HelloIonicPage {
  
          constructor(public nav: NavController) { }
          bleScan() {
              ble.scan([], 5, function(device) {
                  console.log(JSON.stringify(device));
              }, failure);
          }
  }
  </code></pre>
  
  <p>However, <code>ble</code> isn't recognised so my code is throwing errors. Do I need to inject a dependancy or something, why isn't this working?</p>
