title: How does a Bluetooth beacon work with an app?
body: <p>Does a Bluetooth beacon work like this, it transmits ID’s and a phone with BLE detects the ID and sends it to a app looking for ID's which does something if the ID matches one in a database for example</p>
  
  <p>Question:
  Can you connect the Bluetooth beacon to a app and customize what ID is being transmitted like the boss logs in the app and the beacon starts transmitting an ID depending on the time.</p>
  
  <p>The worker logs in the app and it will start listening for ID's and update a database depending on what ID it has received?</p>
  
  <p>Is there handshake that needs to happen for an android app to detect ID’s being transmitted by a beacon or it can receive ID’s from any beacon?</p>
