title: Questions about pairing Bluetooth (Xamrin.ios or ios)
body: <p>I have some questions about pairing Bluetooth.</p>
  
  <ol>
  <li>Is there any events that can help me to get the pair authentication status? (e.g. after typed-password, authenticate success, authenticate fail, etc…)</li>
  <li>Is there any properties I can use to get the pair authentication status? (if question 1 has no solution) (e.g. paired, unpaired, paring)</li>
  <li>How can I remove the Bluetooth authorize programmatically? (it means when I remove the authorize, I will re-type password to pair my device)</li>
  </ol>
