We're using a mesh network for communication among XBees. In the previous section, we applied DigiMesh firmware to our XBee modules. In this demo, we'll develop an application to send data from XBee on an Arduino to XBee on a computer.

First, we configure all XBee modules using XCTU. After opening XBee using XCTU, we can start to configure it. Set Destination Address Low (DL) with FFFF. You can see it here:

You also need to set API Enable (AP) as Transparent Mode [0], as shown in the following figure. If finished, you can write all changes to the XBee:

Implement these steps for both XBee modules.
