title: Is it possible to remote control iOS camera and music without a helper app?
body: <p>I'm making a hardware device that I can program to send any Bluetooth BLE code. How do I make it control my iPhone to:</p>
  
  <ul>
  <li>take a picture</li>
  <li>play/pause music</li>
  <li>next slide in a PPT presentation</li>
  </ul>
  
  <p>These are things that happen on the phone. Phone takes a picture, phone plays music, etc.</p>
  
  <p>Do I need to install or make a companion app on the phone, or can my hardware device just send the right BLE code(s) to the phone?</p>
