title: Bluetooth Difference between pairing and paging, bonding
body: <p>When I study Bluetooth, I am confused to understand Bluetooth connection and pairing, bonding, etc.</p>
  
  <p>As far as I know, Bluetooth Connection has these steps:</p>
  
  <ol>
  <li>Inquiry - discover</li>
  <li>Paging - using the address in Inquiry process, process of forming a connection</li>
  <li>Connection - device can participate actively(Active mode) or put into other mode(Sniff, Hold...)</li>
  </ol>
  
  <p>When we use Bluetooth devices(e.g. Smartphone, Bluetooth Heaset)
  it has these steps:</p>
  
  <ol>
  <li>Discovery devices</li>
  <li>Pairing(exchange other security information like address, PIN Code)</li>
  <li>Connection start</li>
  </ol>
  
  <p>I can't match paging to pairing. Is my understanding right below?</p>
  
  <ul>
  <li>Inquiry = Discover Devices</li>
  <li>Paging = Pairing</li>
  <li>Connection = Connection start</li>
  </ul>
  
  <p>How can I merge above two categories?</p>
