title: How to perform a bluetooth low-energy scan via BlueZ C library
body: <p>I'm new in programming Bluetooth low energy using BlueZ.</p>
  
  <p>I want to develop a native code c to scan nearby devices using a BlueZ API for Bluetooth low energy on Intel Edison.
  I've seen <a href="https://stackoverflow.com/questions/22474714/how-to-scan-for-bluetooth-low-energy-devices-using-bluez-api">this question</a>, but the answer doesn't really help. Any advice?</p>
