title: Bluetooth peripheral does not pair
body: <p>I have written an apple watch app to try to communicate with a bluetooth peripheral which has implemented some custom encryption and pairing process I already managed to implement correctly.</p>
  <p>The device seems not to conform to standards and as such does not indicate that it needs encryption through its chatacteristic properties. After going through the pairing I can write values to it and recieve notifications.</p>
  <p>The problem is that when I disconnect and connect again I have to go through the pairing process again. Also I have noticed that after pairing via other apps the device does a long beep sound which seems missing when I pair it through my app.</p>
  <p>Is there any way to force pairing/binding in CoreBluetooth?</p>
