title: Can BLUNO receive iBeacon signal and determine the distance?
body: <p>I'm trying to make a project where BLUNO will act as the receiver of BLE signal. An event (Buzz, LCD, vibration, etc..) will be activated when the iBeacon gets out of range. 
  I already have the BLUNO with the latest software. I will buy an iBeacon with Apple standards. For now I'm using an iPhone to simulate it.</p>
  
  <p>I want to confirm if BLUNO can act as a receiver rather than an iBeacon itself.</p>
  
  <p>How can I receive the RSSI and derive distance from it? Any libraries or sources?</p>
