Install and upgrade XCTU
XBee Configuration and Test Utility (XCTU) is a multi-platform program developed by Digi that enables
users to interact with Digi radio frequency (RF) devices through a graphical interface. The application
includes built-in tools that make it easy to set up, configure, and test Digi RF devices.
XCTU does not work directly over an SPI interface.
You can use XCTU to update the device firmware, and if needed, XCTU will attempt to update your
cellular firmware. Firmware is the program code stored in the device's persistent memory that
provides the control program for the device.
For instructions on downloading and using XCTU, see the XCTU User Guide.
Note If you are on a macOS computer and encounter problems installing XCTU, see Correct a macOS
Java error.

2. Upgrade XCTU to the latest version. This step is required.
Step 2: Add a device to XCTU
You must add a device to XCTU before you can update the device's firmware or configure the device
from XCTU.
