title: iOS 11 & Ionic 3 implement a BlueTooth connection with BluetoothSerial cordova plugin
body: <p>Im trying to connect a neurosky MindWave (detects brain signals) with this plugin:
  <a href="https://ionicframework.com/docs/native/bluetooth-serial/" rel="nofollow noreferrer">https://ionicframework.com/docs/native/bluetooth-serial/</a>
  provided by Ionic.
  But when I try to discover available devices I'm getting this error:</p>
  
  <blockquote>
    <p>Method 'discoverUnpaired:' not defined in Plugin 'BluetoothSerial'</p>
  </blockquote>
  
  <p>Here's my code:</p>
  
  <pre><code>this.bluetoothSerial.discoverUnpaired().then((success) =&gt; {
    success.forEach(device =&gt; {
        console.log('Device detected! - ' , device);
      });
    },
    (err) =&gt; {
      console.log(err);
    })
  </code></pre>
