TCR Firmware Changelog

All notable changes to the TCR Firmware will be documented in this file. The format is based on Keep a Changelog, and this project adheres to Semantic Versioning.

Versions marked with UPDATE! should not be used anymore.

[1.3.1] - 2021-08-27

Improved noise canceling in the radar processing algorithm leading to higher resolution.

[1.3.0] - 2021-08-22

TCR-HS and TCR-HSS should uptate to 1.3.1

Finding the right sensitivity is now easier as we introduced autotuning. This can be done via CLI or with the new configuration payload (V3).

Improved object counting in a wider range of sensitivity settings as well as with certain usual types of radar reflections. Asymmetric counting (more RTL than LTR) at inaccurate sensitivity settings no longer occurs.

For US915 or AU915 users we fixed the prolem with config downlinks not beeing received due to limited airtime in these LoRaWAN bands. We also updated some default values based on customer feedback to make defaults be a good starting point for most users.

[1.2.4] - 2021-02-17

Minor Bugfixes for AS923 devices allowing to receive config payload now during startup

[1.2.3] - 2020-12-21

Improved sensitivity

[1.2.2] - 2020-12-10

Minor Bugfixes for US915 and AU915 devices allowing to receive config payload and ectendet payloads. Fixed an issue where settings have not been correctly saved.

[1.2.1] - 2020-11-13

radar module update mechanism fixed

[1.2.0] - 2020-11-05 - UPDATE!

Update to V1.2.1 or newer as we found a issue in the update mechanism of the radar module that could lead to a bricked device if power will be cutted in the wrong moment.

FFR firmware is now included in the main firmware and will be automatically updated during startup. During the update both LEDs blink fast. (Please be patient)

Power Consumption

  • TCR-LS 157mW

[1.1.2] - 2020-10-15

Fixes a problem where in the config payload where Payload Speed Groups have not been mapped correctely

[1.1.1] - 2020-09-16

[1.1.0] - 2020-09-15

Indroduces FFR radar algorithm and Payload V2

[1.0.0] - 2020-06-10

First Relase for TCR/TCR-S
