title: Can I implement an iOS App to act as a BLE service?
body: <p>Can I implement an iOS App to act as a Bluetooth low energy service?</p>
  
  <p>I need to be able to programmatically define:</p>
  
  <ul>
  <li>a service UUID</li>
  <li>characteristics for the service</li>
  <li>a way to update the values of these </li>
  <li>a way to define the user permission of the characteristics: read / write / notify</li>
  <li>a way to define the transmission (TX) power of the service</li>
  </ul>
  
  <p>Would appreciate if you could point me out to a good demo / example to get started or even share some code snippet so this can become part of the Documentation of iOS.</p>
