title: Pre-pairing bluetooth devices
body: <p>I would like to be able to pre-pair bluetooth devices, to save the step of user confusion when using the app. I have discovered that there is a patent for
  <a href="http://www.google.com/patents/US20070123166" rel="nofollow noreferrer">System, method and apparatus for pre-pairing bluetooth enabled devices</a>.</p>
  
  <p>I am looking at pairing an array of android devices with an array of embedded devices, so when the android device is set up, I can pre-pair it with the devices it needs to communicate with. I have considered maintaining a list of MAC-addresses that can be downloaded and updated by the app.</p>
  
  <p>Is there a way to pair two devices without having to bring them into contact?</p>
