title: iOS Bluetooth setNotifyValues
body: <p>I have a device that works through Bluetooth, I can connect to it, discover it's services and characteristics (char). However, one of the char is 'repeated' twice, but each with a different property, READ and WRITE. So far so good until I try to subscribe to said char. I get an error. My guess is that, when this is called:</p>
  
  <p><code>[peripheral setNotifyValue:YES forCharacteristic:characteristic];</code></p>
  
  <p>The first char that's found by the program has the WRITE property, hence it fails.</p>
  
  <p>Is there a way to be more specific with which char to setNotifyValues to, like attaching the property to it?</p>
