title: indoor navigation and tracking people using BLE
body: <p>Is there a way to use bluetooth 4.0 and beacons to create in-store navigation?</p>
  
  <p>I am searching for the best way + API to use, for indoor tracking and navigation using <code>Bluetooth 4.0</code>. I know that you can detect if a person is near a beacon or entered the store but I am not sure if you can actually track this person and understand exactly where is he inside the store, using his phone.</p>
  
  <p>Is there a way to do that, and if so what is the best tool to use it?</p>
  
  <p>I also found <a href="http://indoo.rs/" rel="nofollow">indoo.rs</a> but I don't know how accurate is it and if it is the best tool to use. </p>
  
  <p>thanks! </p>
