Release Date



October 2022

This is the newest firmware update for the BLK360. (Download Release Notes)

WHAT's NEW in version 2.1.1

The v2.1.1 is an engineering release which doesn't contain any new features or fixes.

Version 2.1.1 is required to be able to fully use a new batch of the EDM board.

The new EDM board is used in all original BLK360 G1 devices with a serial number of 3509564 or higher

A BLK360 G1 with an updated EDM provides the same scanning performance as a device equipped with the previous batch.

v2.1.1 is fully backwards compatible for devices with serial numbers before 3509564.


July 2021

  • Data transfer over cable
    To have a faster and more robust data transfer of scans from the Leica BLK360 to a computing device v2.1.0 supports the data transfer over LAN cable
  • Data transfer using a direct LAN communication to a computing device
    The direct LAN communication to a computing device requires no existing network structure and can very easily be setup, even when being out in the field. (See release notes for requirements)
  • Data transfer using LAN infrastructure
    The direct LAN settings configures the Leica BLK360 as DHCP server, which provides an IP to the connected computing device
  • Requirements for direct LAN communication
    All BLK360 sensor with a serial number of 3507273 or higher do support the LAN cable feature. All BLK360 devices supporting the LAN communication, will be delivered without the USB-C plug cover.
  • LAN upgrade kit for Leica BLK360
    Leica BLK360 devices with a serial number lower than 3507273 can be upgraded to support the LAN feature.
  • Issue fixed in v2.1.0
    • Memory
      The version 2.0.1 fixes an issue, where the user was not informed when the internal memory was full.

July 2020

  • New Linux operating system & new web interface
    The BLK360 firmware version 2.0.0 uses a new Linux operating system which supports a new web interface for the BLK360. All existing BLK360 functionality is supported and maintained in this new Linux OS.
  • Support of SSID handling inside the web interface
    The new web interface supports hiding the SSID in case users do not want to share or reveal the SSID. Users can also reset the SSID to default settings using the web interface. The appropriate settings are available on the web interface in the sub-menu “Advanced Settings”.
  • Dust/Dirt detection
    The BLK360 executes QA processes during the scan to be sure that the scan data only includes valid measurements, which afterwards can be processed by the according software or app. In case there are invalid measurements due to dust or dirt on the BLK360 mirror, the BLK360 will show an Error state, indicated by the yellow LED ring on the scanner. If the Cyclone FIELD 360 app is used to operate the scanner, an error message will appear within the Cyclone FIELD 360 app. The user can then clean the BLK360 mirror and resume normal scanning.
  • Battery capacity reading
    The battery capacity reading using the 1-wire battery interface sometimes showed inaccurate battery capacity information. This has been fixed and accurate battery capacity readings are shown in firmware v2.0.0.

November 2019

The following issues have been addressed:

  • Resolved all errors with image artifacts and patterns in BLK360 imagery. 

  • Database state detection upon bootup; will reset if needed to avoid bootup error.

  • All tilt measurements correctly averaged for scan-only captures of multiple setups.


August 2019

  • Battery status information not updated.

  • Scan data could be corrupted when captured with firmware v1.2.2


May 2019

  • Reduced scan data size.

  • Enhanced imaging processing.

  • Removal of rare pink mist in LDR and HDR images.

  • Improved brightness control for panoramic images.

  • Automatic update of the SD card to avoid corruption.

  • Extended Scan delay for push-button.

  • Scan only capture for push-button.


December 2018

  • Support of WLAN infrastructure access.

  • Support of additional settings to use the IR-Camera.

  • Support of scan only use-cases without image capturing.
