How to update firmware for BLK360

Release Date



January 2024

WHAT’s NEW in version 1.5.0

(Download release notes)

This firmware update focuses primarily on stability improvements and bug fixes.

  • Fan now switched off when connecting the BLK360 to a computing device via USB-C in low power mode.

Fixed issues:

  • USB-C (Low Power Mode): Connectivity issues.
    With some computing devices the data transfer in the Low Power Mode was not stable. The BLK360 occasionally would restart and therefore the data transfer was interrupted.

    This issue is now fixed, the BLK360 will not restart while connected via USB-C Low Power Mode and the data transfer will be done without interruptions.

  • Tilt: Wrong tilt calculation when capturing upside down setups.
    When upside down setups were captured, the setups would import with a slight tilt.

    Now upside setups are importing with the correct tilt.

  • Webserver:
    Failing to delete data associated to the setup file (job name, links, and bundles).

    Now when deleting setups from the webserver all the data associated to it is also being deleted from the BLK360 internal storage.

  • Minor bug fixes.

    It is recommended to update your Leica BLK360 to the latest firmware version (1.5.0) to benefit from these enhancements.
