title: send data using bluetooth to android mobile without an app?
body: <p>I am working on iBeacon based project to send the push notification to Android devices using Bluetooth wireless technology. Is there any way to send the push notification to Android device without any installed app over the Bluetooth? Basically, iBeacon is connected to Pi using Bluetooth and Pi (Pi 3 with inbuilt Bluetooth) will communicate with Android devices using Bluetooth.  Following are the possible ways to send data/notification to Android devices:</p>
  
  <ul>
  <li>By an installed app</li>
  <li>Push notification through chrome using web-socket</li>
  </ul>
  
  <p>But above both ways are not useful for my task. Kindly allow me to know if there is any way to do it.</p>
