title: IPhone Bluetooth Connectivity to Non IOS Devices
body: <p>I was wondering, if there is a way to use IPhone as an HID device, with some other device like PS3. I checked out the Bluetooth specification and IOS Devices do support HID Profile. So I thought it would be easy to pair my iPhone using passkey mechanism and should be able to start using my iPhone as keyboard or mouse without much hassle. But I found very soon that this assumption is naive and I need to develop custom solution.</p>
  
  <p>I was initially thinking about using GameKit framework, but I think it only works  between two compatible IOS Devices. If I want to extend this capability, then I have to use iPhone External Accessory API .In my analysis, I also found that iPhone will only communicate and pair with devices that are licensed by Apple. (Made for iPhone\iPod program). Does it mean that, if I want to use iPhone with another device, I need to get that device approved by Apple. ( Which will not surprise me one bit). Also if someone could point me to more detailed documentation on this, that will also be helpful.( What is an MFI developer board ??)</p>
  
  <p>I do not want  a solution that needs me to jailbreak an iPhone. (or any solution that will disqualify my app by Apple).</p>
  
  <p>So to summarize:</p>
  
  <p>1- Please validate my findings, correct them if they are wrong?</p>
  
  <p>2a- How does External Accessory API Work? 
   b- Can I use this to connect to third party accessories ? (or is this only for accessory developers).</p>
  
  <p>3- Or is there a better solution without using External Accessory API?</p>
  
  <p>Please provide supportive documentation or link if you can. Thank You.</p>
