Connect a loopback jumper to an XBee device

Connecting a loopback jumper to an XBee device lets you send a message to another XBee device and have the message loop back to the sender.

1. Connect the loopback jumper on XBEE_B so it bridges the two pins on its development board.

   

2. In the XBEE_A console, click the Clear session button to clear your previous conversation.
3. Type Hello!

   Each character loops back in the XBEE_A console log, which indicates that XBEE_A successfully sent the message to XBEE_B.

   

   You are now ready to use the loopback jumper to help you test a mesh network consisting of three XBee devices.
