Mobile Anchor Distance Measurement Test by OS

Hello, this is Freegrow. Today, we introduce a simple test using our Mobile Anchor. We wanted to see how far the distance can be measured on Android and iOS. One of the most common questions from users is: “How far can my smartphone stay connected to the Mobile Anchor?” So we ran the same test […]

UWB DIY Failure: What We Learned and Why We Chose the UWB Creator Kit

Hello, this is Freegrow. When you prepare a capstone design or graduation project, you may think,“Maybe we can save money by building the module ourselves?”Most of you have probably thought about this at least once. The case I will share today also started with that idea. A university student project team wanted to build a […]

[ESP32 Tutorial] GrowSpace UWB Tag Integration Guide – Receiving Position Data

This guide describes how to connect a GrowSpace UWB Developer Tag to an Arduino ESP32 board, send lec and lep commands, and receive and parse real-time location data. Unlike the UNO, the ESP32 supports multiple hardware serial ports and is highly scalable with a compact footprint—making it ideal for lightweight test environments. Required Components To […]

[Part 1] GrowSpace UWB Serial Connection Guide – From Installing Tera Term to Initial Setup

This guide explains how to connect GrowSpace UWB devices (Anchor, Listener, Tag) to a PC using the Tera Term program for serial communication.Users can follow the step-by-step instructions to install the necessary tools, establish a connection, and prepare for command input and data reception. Requirements To begin serial communication, please prepare the following: Installing Tera […]

Improving Z-Axis Accuracy: Anchor Placement Tips for the GrowSpace Q1 Kit

The GrowSpace Q1 Kit is a UWB-based RTLS system capable of measuring the 3D coordinates (X, Y, Z) of tags in indoor environments in real time.By default, the XY plane (horizontal) positioning performs reliably in most environments. However, the accuracy of the Z-axis (height) measurement may vary depending on the anchor installation structure. 📌 If […]

6. Listener Map Setup Guide

In this guide, we’ll introduce how to set up indoor maps (floor plans) in the GrowSpace UWB system.We’ll guide you step by step to ensure that the tag’s location updates in real-time on your map as it moves. Why Set Up a Map? The UWB system measures tag positions as numerical coordinates (X, Y, Z).However, […]

5. Listener Setup Guide

So far, we’ve covered how to set up Tags and Anchors.Now, we’ll explain the final step: configuring and integrating the Listener. What is the Listener’s Role? The Listener is a core device that collects tag data and integrates it with your system.If this process is not configured properly, real-time location tracking will not work, so […]
