Open Source Communication Debugging Tool Supporting Modbus and MQTT

Introduction

A communication debugging tool developed based on WPF, featuring a user-friendly interface and easy operation. It supports both Modbus and MQTT protocols, enabling debugging of various communication methods. Whether in industrial automation, smart home, or IoT fields, this tool can meet your needs. Additionally, the code is open source and modular, making it highly effective for both learning and debugging.

Technologies Used

Communication debugging tool developed with C#, WPF, Prism, MaterialDesign, and HandyControl, supporting Modbus RTU debugging and MQTT debugging.

Software Features

1. 1. Supports Modbus RTU, MQTT server, and MQTT client

2. 2. Rich color interface

3. 3. Automatic parsing of Modbus RTU data frames

4. 4. Intelligent prevention of packet sticking, fast parsing (frames that cannot be verified may result in errors)

Function Introduction

Modbus RTU

1. 1. Automatic formatting, parsing, and verification of data frames

2. 2. Custom frames with automatic verification support

3. 3. Device search with multiple combinations for automatic device discovery

4. 4. Data monitoring with configurable byte order, data types, etc., supporting read and write operations

5. 5. Automatic response

MQTT Server

1. 1. Start an MQTT server locally for client connection testing

2. 2. Right-click messages to format and view JSON data

MQTT Client

1. 1. Start an MQTT client to connect to the MQTT server

2. 2. Provides subscription management, allowing subscriptions and unsubscriptions

3. 3. Right-click messages to format and view JSON data
