    Download and show regulatory firmware

    Regulatory firmware is used for regulatory testing purposes and in most cases the available settings are limited in XCTU.

    Check this setting if you want XCTU to download and install regulatory firmware from the FTP when executing the Update the Radio Firmware Library operation. It will also show regulatory firmware in the following dialogs so that you can inspect it or flash it in an XBee module:

    • Update Firmware dialog
    • XBee Recovery tool
    • Firmware Explorer tool

    Uncheck the setting if you do not want to download or see regulatory firmware.
