All notable changes to the PCR2 Firmware will be documented in this file.
Versions marked with UPDATE! should not be used anymore.
Finding the right sensitivity is now easier as we introduced autotuning. This can be done via PCR Setup Tool, CLI or with the new Configuration Payload V5. Autotuning will be turned off automatically after 20 detections.
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.
Radar can be disabled by configuration downlink. This allows to save energy on solar powered devices.
AppEUI/JoinEUI is now 8CAE49CFFFFFFF01 for all PCR2 in preperation for our future Join Server
Please update your encoders/decoders to the new Configuration Payload V5. Use PCR Setup Tool V6.18.1 or newer to access PCR2 with firmware V3.10
Update to V3.10.0 if you have issues with near field counting
Updated Radar Algorithm for PCR2 indoor models. Users are now able to disable the AutoSens mode. This is useful in noisy environments.
Fixed some LoRaWAN networking issues for AS923 devices.
Improved measurement accuracy for PCR2-IN and PCR2-XIO devices on situations where people passing by very close to the sensor (less than 2 m)
Update if you have an US915 device and using a gateway with only 8 channels.
Update if you need to fine tune near distance trackings (COVID-19 lamps)
FFR 1.4.5 firmware is now included in the main firmware and will be automatically updated. During the update both LEDs blink fast for about 30s
Update introduces the new FFR Radar Processing. Better performance for PCR2-IN/XIO when people pass by very close
No need to update working PCR2-IN/OD/R/T devices as this version won’t correct anything.
Update if you are using XIO Downlinks
If you need to set capacity limit to more than 1000 persons
Update if you are using XIO Downlinks.
Update if you need the extended payload format
This is the first firmware that operates with the new PCR2-XIO devices with integrated digital outputs. PCR2-XIO devices have been released for various COVID-19 applications but can also be used as industrial counters connected to an external controller.
First version for PCR2 Rev.03 devices
This procedure is for hardware rev. 03 devices only.
1. Check Hardware Revision
Please find the PCB number printed on the backside of the PCR2 mainboard.
Look for 1714-PCB0000-03 or 1714-PCB0000-04.
2. Connect your PCR2 to your PC
Connect your PCR2 with an USB cable to your Windows10 PC and start PCR Setup Tool.
3. Start Firmware Updater
Please start Firmware Updater and check if there is a new version available. Then follow the instructions of the wizard.
4. Reconnect Device
Plug out and plug in device and check updated firmware version
