PCR2 Firmware 3.3.x

The following documentation relates to PCR2 Firmware V3.3.x only.


Device startup sequence

After switching on the device, following sequence will start.

  1. Initialization of Radar Processor. LEDs are constantly on.

  2. Start Join-Procedure (only if LoRa Modem is enabled). LEDs are blinking slowly

  3. After receiving Join Accept, the device switches to detection mode

Detection mode

  1. LEDs are off and are quickly flashing if a object gets detected.

  2. After Interval time is up, the device sends the PCR2 Application Payload. This can be done in Confirmed or Unconfirmed Mode.

  3. In Confirmed mode LEDs are on until successful 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.

Firmware Changelog

[3.3.2] - 2020-05-27

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)

[3.2.0] - 2020-04-06

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.
