title: iOS - discovering roving network's RN-42 BTLE chip
body: <p>I am working on a project where I have to discover a bluetooth chip provided by Roving Networks - <a href="http://www.rovingnetworks.com/Apple_iOS_Support" rel="nofollow">RN-42</a>. The development kit come with an ios application which shows how to communicate with the chip but first we have to connect/pair (manually) with the chip using iOS settings. It uses EAAccessory Framework and works fine. 
  What I want is to discover the bluetooth chip from my application and then connect/pair with it automatically but I cannot find a way on how to do that. I am using CoreBluetooth framework to discovery the chip but nothing comes up. Here is how I try to scann for BT devices using CBCentralManager </p>
  
  <pre><code>[self.centralManager scanForPeripheralsWithServices:nil
                                              options:nil];
  </code></pre>
  
  <p>But I don't get anything back in the callback.</p>
  
  <p>Thanks</p>
