title: Connecting to a Bluetooth device from iOS, no MFi
body: <p>The vibe I'm getting from Stackoverflow and the internet at large is that unless I'm using an LE device, any Bluetooth device I make for an iOS app must be MFi certified.</p>
  
  <p>However, on the <a href="http://mfi.apple.com/faqs">MFi FAQ</a> page, I found this line:</p>
  
  <blockquote>
    <p>...developers of accessories that rely solely on standard technology
    (e.g., Bluetooth Low Energy or standard Bluetooth profiles) do not
    need to join the MFi Program.</p>
  </blockquote>
  
  <p>My device will be able to use the standard Bluetooth profile <a href="http://en.wikipedia.org/wiki/Bluetooth_profile#File_Transfer_Profile_.28FTP.29">File Transfer Protocol (FTP)</a>.</p>
  
  <p>Now this sounds like some conflicting advice to me, or perhaps I'm just not understanding correctly. So, having provided the above evidence, I'm just going to ask outright: Can I write and publish an iOS app that connects to a proprietary Bluetooth device using the standard Bluetooth profile FTP without certifying my device as MFi? And if so, what details, caveats, etc do I need to know?</p>
