Hardware
The In-Circuit radino40 DW1000 combines Nordic Semiconductor 's nRF52840 microcontroller and Decawave's DW1000 UWB radio chip in a small form-factor EMC-compliant module.
The DW1000 is a fully integrated single chip Ultra Wideband (UWB) low-power low-cost transceiver IC compliant to IEEE802.15.4-2011.
It can be used in 2-way ranging or TDOA location systems to locate assets to a precision of 10 cm. It supports data transfer at rates up to 6.8 Mbps.
The Nordic Semiconductor's nRF52840 with 32-bit ARM® Cortex®-M4 CPU mit FPU, 64 MHz Clock, 1Mb flash, 256 MB RAM offers great performance and Bluetooth 5 functionality. The radino40 modules are pin-to-pin compatible.
With its powerful processor, the DW1000 UWB-chip and its small size, the radino40 DW1000 is the perfect base for RTLS-systems

Software
Firmware-Update via USB Bootloader
Required Software
The radino40 DW1000 is shipped programmed with a usb bootloader which can be used to upload new firmware.
The USB driver needs to be installed, it can be downloaded here
Also the nrf_util tool has to be installed, it can be downloaded here (additional information regarding this tool can be found on nordicsemi.com or github.com)
The compiled firmware binaries are delivered within a compressed zip file dfu_container.zip.
Starting the bootloader
Enable the bootloader on the radino40 DW1000 via low on the reset pin, e.g. by pressing the RESET-Button. The radino40 DW1000 stays in bootloader mode for 2 seconds. After that the Firmware is running.
The bootloader will be recognized as a serial COM-Port, e.g. COM4.
Upload firmware with nrfutil_cmd
On a windows PC open a Command window (cmd.exe) and navigate to the folder that contains the firmware file dfu_container.zip.
Replace COM4 with the COM-Port that your PC assigned to your device.
command to flash:
nrfutil_cmd dfu usb-serial -pkg <dfu_container.zip> -p <COM Port: COM4> -b 115200
example:
nrfutil_cmd dfu usb-serial -pkg dfu_container.zip -p COM4 -b 115200
Start the nrfutil_cmd.
The nrfutil_cmd now waits up to 10 seconds for the radino40 DW1000 to enter the bootloader.
If the nrfutil_cmd exits successful the radino40 DW1000 is programmed.
