Overview

This community project by ethanetExplorer demonstrates practical distance tracking between two Makerfabs ESP32 UWB devices. It focuses on achieving maximum range and accuracy through proper antenna delay (Adelay) calibration, a step often skipped in basic examples.

Key Features

  • Long range: ~130 meters in line-of-sight conditions
  • Obstacle tolerance: Works through pillars and behind walls
  • High accuracy: ±20 cm precision with proper calibration
  • Antenna delay calibration: Includes calibration procedure for optimizing accuracy
  • WiFi connectivity: Tag supports WiFi for data transmission

Important Note

The project requires the specific modified DW1000 library from Makerfabs — standard DW1000 Arduino libraries only achieve ~40 meters maximum distance.

Hardware Required

  • 2x Makerfabs ESP32 UWB devices (compatible with UWB Pro with Display)
  • USB cables for programming
