Building Your Own Server

In This Guide

This guide explains how to use MQTT-Studio to connect to the Mosquitto broker and subscribe to the real-time UWB location data sent from the GrowSpace Gateway. When you want to integrate the tag and anchor location data with a server or cloud system via the MQTT broker, setting up the MQTT subscription environment as described in this guide will make the data integration process much easier.

⚠️ If you are setting up or configuring the MQTT server (Mosquitto broker) for the first time, please refer to the document below to prepare your server environment. Go to the MQTT Server Setup Guide

However, even before setting up the server, you can configure a test environment using MQTT-Studio. We recommend following the steps in this guide to learn the process of connecting to the broker and subscribing to data. This will help you familiarize yourself with the steps before the server setup.


Creating a Project in MQTT-Studio

Creating a Project

  • Open MQTT-Studio.

  • In the left menu, click New Project.

  • Enter the following details:

Item
Description

Project name

Project name (e.g. growspace-test)

MQTT Broker

IP address of the PC where the Mosquitto broker is installed

Port

Keep the default port 1883

Client ID

Enter a unique, random name (e.g. testclient1)

Username / Password

Enter settings according to the broker configuration, or leave it blank if not required

If connecting within the same network, simply enter the IP address to establish the connection.

For external connections, you will need to configure port forwarding on the router for port 1883.

  • Once the connection is successfully established, the status in the top right corner will change to CONNECT.


How to Check the IP Address (Windows)

  • Type cmd in the Windows search bar and open the Command Prompt.

    • Enter the command ipconfig and press Enter.

  • In the output, locate the IPv4 Address field. Example: 192.168.0.101

* Use this address(주소) as the IP for the MQTT Broker.


Configuring Gateway Data Subscription

After connecting to the Mosquitto broker, subscribe to the topics in MQTT-Studio to receive location data.

  • Click the + button in the top-right corner.

  • Enter and add the following 3 topics:

Topic
Description

uwb/gateway/start/#

Gateway Boot Status Information

uwb/gateway/config/#

Configuration data, including settings and measurement intervals

uwb/gateway/devices/#

Real-time location data of tags and anchors

The # symbol subscribes to all subtopics within the specified path. The projectId included in the topic structure is configured based on the API key issued on the GrowSpace Web Configuration page.


Saving the Project

Once the topics are registered, click Save Project in the top-left menu to save the configuration. You can later quickly reconnect with the same settings by selecting Open Project.


Gateway Configuration and Data Transmission

Through the GrowSpace Web Configuration Page, you can configure the GrowSpace Gateway Q1 device to send data to a private Mosquitto broker.

Configuration Steps

  • Connect the power to the gateway.

  • Open Google Chrome and navigate to the following web page. https://uwb-gateway.web.app

  • From the top menu of the page, go to the Gateway Settings section.

  • Enter the required details in the fields below.

Item
Description

Wi-Fi Name / Password

Enter the 2.4GHz Wi-Fi information (5GHz is not supported)

MQTT IP

Enter the IP address of the PC where the Mosquitto broker is installed

  • After filling in all the fields, click Save. The gateway will automatically restart and begin sending data to the configured MQTT broker.


Confirm Data Reception in MQTT-Studio

Once the gateway configuration is complete, real-time location data will begin to appear automatically in MQTT-Studio. Below is an example of the actual received message.

swift복사편집Topic: uwb/gateway/devices/project-1234/TAG-001
{
  "tagId": "TAG-001",
  "x": 12.34,
  "y": 56.78,
  "z": 1.23,
  "timestamp": 1723850283
}

Using this data, you can check the tag’s location or integrate it with a real-time monitoring system.
