WHAT`s NEW in version 1.2.0

(Download release notes)

The firmware v1.2.0 provides general fixes and stabilisation as well as improvements and features.

In few occasions the all-new BLK360 went into yellow LED warning state during or after data capturing, and in rare cases, the red LED error state was prominent at startup or while data capturing.
These issues have been identified and consequently be fixed, improving the overall system performance and making it significantly more stable.

In especially challenging and wifi polluted environments the BLK360 lost sometimes the connection to mobile devices.
Improvements have been made in this area, leading to a more stable WiFi connection to mobile devices where the apps BLK Live or Leica Cyclone FIELD 360 are running.

Although the VIS in the small but powerful system performs already well in typical environments, the VIS is tuned with FW 1.2.0 to be more robust even in some challenging scenarios, without reducing the responsiveness when sensor movement is shown in BLK Live or Leica Cyclone FIELD 360.
Robustness has been increased by tracking more features used for trajectory calculation.

In some special usecases like dark environments or measuring on moving and vibrating undergrounds, like ships, it is recommended to turn off VIS in order to be able to use the all-new BLK360.

If VIS is enabled in dark conditions, the device might go into warning state because not enough visual features can be reliably detected.
In the other use case of measuring on vibrating undergrounds, VIS could interpret this as an active movement of the device and could calculate a wrong sensor position.

The feature to turn on/off VIS will be supported by the next official release for BLK Live in v1.0.3 and Leica Cyclone Field 360 in v4.0.3.

Leica Geosystems' patented Visual Inertial System (VIS) technology, is now built into the new BLK360 to automatically combine your scans.

Each captured scan in the field is combined with your previous scan. You'll spend less time aligning data and more time creating valuable deliverables.

Once the BLK360 is moved after the first scan, the LED ring will start blinking green, indicating that cameras and IMU are tracking its position. After the imaging laser scanner is placed on the ground, the LED will switch to constant, non blinking green, indicating that it is ready for capturing the next scan.

The imaging laser scanner knows its relative position to the previous scan which enables a very fast preregistration directly on site with Leica Cyclone FIELD 360.

The pre-registration information is synched back to the BLK360, so all information is stored on the imaging laser scanner when downloading the data directly from the device to Leica Cyclone REGISTER 360 PLUS and Cyclone REGISTER 360 PLUS (BLK Edition).


Enjoy real-time data synchronisation between your devices with the BLK360's onboard wireless connection, then transfer data with speed and stability via WiFi or its USB-C port.

The transfer speeds are:

  • up to 450 Mbit/s over USB-C and
  • up to 100 Mbit/s over WiFi

There are 2 different data transfer modes available for USB-C:

  • High power mode
    In high power mode the maximum data transfer speed of up to 450 Mbit/s is available. To start the high power mode, the BLK360 needs to be started up before connecting to the cable. In this mode, the BLK360 is powered by the internal battery. Data transfer will stop once the battery is empty.
  • Low power mode In low power mode, the data transfer speed is approximately 10% lower as in high power mode. To start the low power mode, plug the USB-C cable in the turned off BLK360. The device will automatically be turned on. In this mode, the BLK360 is powered by the connected computing device and at the same time, the battery gets charger. The low power mode is not timely limited by the internal battery and therefore the ideal mode to transfer a huge amount of data.


A direct USB-C cable must be used like the one included in the starter package of the BLK360. Data capture is not possible when the BLK360 is connected via USB-C.

The cable setup for BLK360-G1, which includes a USB-C to Ethernet adapter, does not work with the new BLK360.


The webserver is a useful tool to perform the following functions

  • Update the firmware (Device menu)
  • Download service reports (Device menu) and scan raw data (Scans menu) if required for a support case
  • Check free disc space
  • Indicate if the BLK360 is in low power mode and the related benefits as well as limitations

Webserver access:

When connected via WiFi to the BLK360, enter in the browser.

When connected via USB-C to the BLK360, enter in the browser.


A small half circle in the zenith of the imaging laser scanner will be present in the captured scan data, this is related to the characteristics of the ultra-fast LiDAR sensor. 

If required, this gap can fast and easily be closed by another scan nearby that covers that area.


Occasionally in sunny outdoor conditions, the point cloud of the BLK360 might contain ghost points which are directed towards the sun.

If required, these ghost points can easily be deleted by using the "delete" function in Cyclone REGISTER 360 PLUS.

This known issue is addressed and expected to be solved soon in an upcoming release.
