title: Android phone doesn't recognize Arduino board
body: <p>I have a <a href="http://en.wikipedia.org/wiki/Samsung_Galaxy_Gio" rel="nofollow">Samsung Galaxy Gio</a> and want to connect it to an <a href="http://arduino.cc/en/Main/ArduinoBoardLeonardo" rel="nofollow">Arduino Leonardo</a>. I use the <a href="http://store.iteadstudio.com/index.php?main_page=product_info&amp;products_id=307" rel="nofollow">Stackable Bluetooth Shield 2.1</a> from ITead Studio.</p>
  
  <p>It works with a Windows PC (I can send and receive strings with <a href="http://en.wikipedia.org/wiki/PuTTY" rel="nofollow">PuTTY</a>), but my phone doesn't even recognize it - the <a href="http://en.wikipedia.org/wiki/Bluetooth" rel="nofollow">Bluetooth</a> device list is empty.</p>
  
  <p>The strange thing is that a <a href="http://en.wikipedia.org/wiki/Samsung_Galaxy_S" rel="nofollow">Galaxy S</a> recognizes the Arduino immediately. And my phone can see all other Bluetooth devices - except the Arduino.</p>
  
  <p>Why can't my Gio recognize the board, when all other devices work?</p>
