title: In XBee ZigBee, how to get RSSI of all end-devices from coordinator
body: <p>What is the right way to get RSSI for each end-device?</p>
  
  <p>Scenario: Using ZigBee firmware on XBee Series 2 radio modules, API mode, I have one coordinator and multiple end-devices. Every few seconds, each end-device sends the coordinator a packet contains sensor information such as temperature...</p>
  
  <ol>
  <li><p>I don't see RSSI field in any API frame to parse.</p></li>
  <li><p>If I just blindly read pin6 (or using DB command) which stored RSSI of the last received packet, I still don't know which end-device this RSSI belongs to.</p></li>
  </ol>
