DW1000 Tag

Hardware

Tag for Ranging / RTLS applications with radino32 DW1000 Ultra Wide Band module.

Features:

The DW1000 Tag is shipped programmed with a closed source firmware based on the dw1000 advanced demo from our radino Library.

Extended functionality of the DW1000 Tag firmware

The stm32 enters stopMode when there is no activity to save as much power as possible

Functionality contained in the dw1000 advanced demo

USB used as configuration interface (wireless channel, transmit power)
When USB power is detected, the measuring algorithm is paused
Measure and transmit battery voltage
When no movement is deteceted for 30 seconds the DW1000 is put to sleep and the stm32 goes to idle (checking every 2 seconds if there now is movement)
While USB power is detected the LEDs flashing signals charge state of the battery (Green:>4.125V,Yellow:>3.8V,Red:<3.8V)
A succesfull distance mesurement is signaled by a LED flash (Green:RSSI>-75dBm,Yellow:RSSI>-90dBm,Red:RSSI<-90dBm)
While turned upside down the battery voltage level ist signaled on LED (Green:>4.0V,Green/Yellow:>3.75,Yellow:>3.5V,Yellow/Red:>3.25,Red:<3.25V)

Working with the firmware command mode

Connect the DW1000 Tag to your PC via USB
Start a terminal program (e.g. PuTTY, HTerm, Hyperterminal, ...) with 57600 baud and 8N1
- STM32 virtual com port driver need to be installed
After opening the connection press <Enter> once to display the menu

Available commands:

All commands will be send by <Enter>.

aYYYY

Set address to 0xYYYY. This overides the ID set during production. (Vaild values: 0x0000 to 0xFFFF)

cX

xYYZ

Toggle execute measurements. The module communicates with the anchors and prints out results even when powered by USB.

store current configuration to EEPROM (The F option is not stored and reset on USB disconnect)
