title: iPhone BLE / GATT interface
body: <p>I am developing a BLE library for Node JS. I discovered my own iPhone and I found the following GATT services and characteristics:</p>
  
  <pre><code>service d0611e78bbb44591a5f8487910ae4366
  characteristic { uuid: '8667556c9a374c9184ed54ee27d90049',
    props: [ 'write', 'notify', 'extendedProperties' ] }
  
  service 9fa480e0496745429390d343dc5d04ae
  characteristic { uuid: 'af0badb15b9943cd917aa77bc549e3cc',
    props: [ 'write', 'notify', 'extendedProperties' ] }
  
  service 180f
  characteristic { uuid: '2a19', props: [ 'read', 'notify' ] }
  
  service 1805
  characteristic { uuid: '2a2b', props: [ 'read', 'notify' ] }
  characteristic { uuid: '2a0f', props: [ 'read' ] }
  
  service 180a
  characteristic { uuid: '2a29', props: [ 'read' ] }
  characteristic { uuid: '2a24', props: [ 'read' ] }
  </code></pre>
  
  <p>Now I am wondering what they do. Is there any documentation / specification for this? I could not find much by googling.</p>
