title: Arduino: XBee mesh network
body: <p>I'm a newbie with XBeeS2 module. I have several XBee "router" and 1 XBee "coordinator" on my home area network.</p>
  
  <p>A couple of questions:</p>
  
  <ul>
  <li>Can I change from my application (Arduino) the XBee address? Or each XBee address must be configured before with the X-CTU tool (or another one)?</li>
  <li>From my XBee "router", how can I retrieve the XBee "coordinator" address from my application (Arduino)?</li>
  </ul>
