title: Is it possible to connect iOS and android device using Bluetooth?
body: <p>I have to make an application to pair an iOS and Android device (iPhone 5, iPad 3, Galaxy S3, Nexus 7 they all use Bluetooth 4.0) and then send data to each other.</p>
  
  <ul>
  <li>Is this amount of data limited ? Can we send something like a photo or a PDF?</li>
  </ul>
  
  <p>I've already done the pairing and sending data between 2 iOS devices using CoreBluetooth and the sample code from Apple <a href="http://developer.apple.com/library/ios/#samplecode/BTLE_Transfer/Introduction/Intro.html" rel="nofollow">BTLE_Transfer</a></p>
  
  <p>Of what i understood, a Peripheral (Server) can Advertise to a Central (Client).
  This central is scanning around itself, and then try to find the Server by looking for the UUID of the service advertised.</p>
  
  <p>When i make a Server on Android, it is waiting for a connection (listening), i know the UUID and the mac address of my Server.
  But when i scan with my iPhone (scanning for the same UUID of course), i can't find the server.</p>
  
  <ul>
  <li>So is there a possibility for the android server to advertise like the Peripheral on iOS?</li>
  <li>Or maybe a possibility for my iPhone client to connect using the mac address of the server?</li>
  </ul>
