MaUWB_DW3000 with STM32S3 AT Command

Introduction

Ultra-wideband (UWB) is a short-range wireless communication protocol operating via radio waves that enables secure and reliable ranging and precise sensing, creating a new dimension of the space environment for wireless devices. However, in practical application, the most problem of UWB is the signal mutual conflicts/interference, that when there multiple anchor& tags exists. So Makerfabs solved the problem by creating the MaUWB.MaUWB module integrates MCU and all RF circuits, antennas, power management and clock circuits. This module can be quickly configured and used by AT command,supports max 8 Anchors + 64 tags in application, to create a multi-anchor multi-tag positioning system, and supports antenna delay settings for tags and anchors.

Arduino IDE preparations

  1. Install the Arduino IDE V1.8.10/V1.8.19.

  2. Install the ESP32 board package.

All projects are based on the ESP32-S3 development board, guaranteeing higher compatibility and stability.If you haven't installed the ESP32 Board SDK yet, follow the steps in this guide to get started quickly.

  1. Install "SSD1306" library(Version2.5.10).

Arduino has its own library manager, and for some authenticated third-party libraries, it can be searched in the library manager. Click install. Common libraries such as SSD1306.

  • Select "Sketch > Include Library > Manage Libraries", search ssd1306 and click Install.

The ESP32S3 controller can get the UWB arranging result simple by AT commands.

1. One Anchor + one Tag

This is the example to get the distance and signal strength value from Tag0 to Anchor0.

Set the board to Tag0

Open the Set to Tag0 by Arduino IDE.

Use Type-C USB cable to connect the board and PC, and select the development board "ESP32S3 Dev Module" and the port.

  • Select "Tools > board:"xxx" > ESP32 Arduino > ESP32S3 Dev Module".

Set the board to Anchor0

The steps are the same as Set the board to Tag0.

Open the Set to Anchor0 by Arduino IDE.

Use Type-C USB cable to connect the another board and PC, and select the development board "ESP32S3 Dev Module" and the port.

Verify the code and upload.

When it is successful,open the Arduino IDE serial monitor, and you can see the distance and signal strength value from Tag0 to Anchor0.
