title: Callback on device connecting to Wifi Hotspot
body: <p>I am creating WiFi AP programmatically in my application. Do i get any broadcast when new devices connect to my AP. </p>
  
  <p>I know we can get the list of the connected devices from the <strong>/proc/net/arp</strong> but i need a callback when there is a new connection.</p>
  
  <p>Any help is appreciated.</p>
