Digi XCTU can directly update any Digi XBee® firmware so that users always have the latest features. It can also wirelessly update firmware over the air for remote modules. Simply add a remote module to Digi XCTU’s device list and proceed normally for OTA upgrades. The Digi XBee3® modules can even change protocols from Zigbee to 802.15.4 to DigiMesh® simply by loading new firmware. Digi XCTU will notify a designer when updates are available so they’re always in charge for functionality, features, and compliance.
