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. Firmware is the program code stored in the device's persistent memory that provides the control program for the device.

Note You cannot update the cellular component on a 3G 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.
