The following documentation relates to PCR2 Firmware V3.3.x only.
After swithing on the device, following sequence will start.
Initialization of Radar Processor. LEDs are constantely on.
Start Join-Procedure (only if LoRa Modem is enabled). LEDs are blinking slowly
After receiving Join Accept, the device switches to detection mode
LEDs are off and are quickly flashing if a object gets detected.
After Interval time is up, the device sends the PCR2 Application Payload. This can be done in Confirmed or Unconfirmed Mode.
In Confirmed mode LEDs are on until succesfull received a ACK. After receiving the ACK LTR and RTL counters will be reset. If the device operated in Unconfirmed Mode counters will be immediately reset after sending w/o waiting for an ACK.
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.
V3.3.2 enables the NFC chip. In combination with our Android App you can access data directly by touching the front with your phone.
We also optimized the Antenna gain for better outdoor coverage. (Thanks Digita for the feedback)
Firmware used for PCR2-T2 devices only. Needs radar firmware V2.2.0 for the speed detection in order to work.
PCR2-T2 will be replaced with TCR devices.
Added Cacapcity Counting Mode for COVID-19 counting applications
Removed the Uplink Interval limit. Uplink Interval can be set between 1-1440 min.
Please make shure you stay in the limits of your LoRaWAN network provider regarding maximum duty cycles allowed.
Minor Bugfix: Update only if you are using the CLI restart command
Minor optimizations in the Radar sequence timing. Update if you are not happy with power consumption.
First version for PCR2 Rev.03 devices forked from V2.0.4. We habe a Boot Button on the board for easy and save firmware updates. PCR Setup Tool now has integrated firmware update wizzard
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
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 wizzard.
4. Reconnect Device
Plug out and plug in device and check updated firmware version
