title: RN42-APL dev board not authenticating when receiving transmit bytes
body: <p>I recently received the Microchip/Roving Networks RN42-APL development kit from Avnet, and I am able to get the sample iOS app to run and do loopback tests and everything is great (BT connects, authenticates, aware that app is on).</p>
  
  <p>However, when I place this board in a real circuit, where data is flowing to the RX-In pins, the RN42 won't even authenticate! </p>
  
  <p>Has anyone seen a functional example of this MFI chip? The whole 'it just works' isn't really ringing true. Is there something I need to -do- before this chip can send and receive data?</p>
