Firmware Changelog

Version

v3.0.1

Date

2023-02-08

Description

“Updated”

  • beam_to_lidar_transform for Rev7 OS0 and OS1 sensors.

  • lidar_to_sensor_transform for Rev7 OSDOME sensors.

“Added”

  • New HTTP Command to configure speed override (Refer to System)

Version

v3.0.0

Date

2023-01-26

Description

Firmware versions (3.0 & later) are only compatible on OS0/OS1/OSDome Hardware versions Rev7 and later. Please refer to FW 2.x or prior if you have hardware versions Rev7 OS2, Rev 06 OS0/OS1/OS2 and prior generation sensors.

“Fixed”

  • Bug Fix in High Input Voltage Alert behavior.

  • Bug in keep-alive behavior for HTTP 1.1.

  • Bug fix in get_lidar_data_format.

“Improvements”

  • Improved point cloud behavior due to enhanced retro-reflector range accuracy improvement.

“Changed”

  • Default value of udp_profile_lidar will be set to single return profile. For more information refer to Single Return Profile.

“Added”

  • 1024x20 and 2048x10 lidar modes with dual returns.

  • Shot limiting status flags and thermal shutdown.

  • Azimuth laser masking.

  • Two new Signal multiplier modes - 0.25 and 0.5 Mode.

  • New alerts, refer to Table of All Alerts and Errors.

Version

v2.4.0

Date

2022-08-31

Description

“Fixed”

  • Bug Fix in High Input Voltage Alert behavior.

  • Range aliasing improvement.

  • Bug in keep-alive behavior for HTTP 1.1.

  • Critical bug fix: Heavy vibration can trigger the sensor to reset without any alerts, causing an interruption to the data stream. The data stream will resume in approximately 60s. Note: Only affects FW version 2.3 and later.

“Changed”

  • pixel_shift_by_row value updated.

  • Alerts and Errors table has been updated to provide more information on each individual alert.

“Added”

  • Add the following HTTP Commands to help configure and read the sensor config parameters (Refer to Sensor Metadata for more information): 1. GET /api/v1/sensor/config. 2. POST /api/v1/sensor/config.

  • New optional argument for both TCP/HTTP commands “summary” for get_alerts command.

    Note: Valid uses of get_alerts:

    • get_alerts 1 (1 is the value of the cursor).

    • get_alerts summary.

    • get_alerts 2 summary (2 is the value of the cursor).

    Invalid uses of get_alerts:

    • get_alerts summary 2.

“Removed”

  • auto_start_flag has been deprecated.

  • udp_ip has been deprecated.

  • base_pn, base_sn and proto_rev have been deprecated.
