IoT: MQTT Client & UDP Bridge

The ultimate tool for IoT Developers, Network Engineers, and Home Automation enthusiasts.

Transform your smartphone into a powerful IoT Gateway.

This application combines a robust MQTT Client with a flexible UDP Server, enabling seamless bi-directional communication between cloud brokers and local hardware like ESP32, Arduino, Raspberry Pi, or PLCs.

Unlike standard network tools, this app is designed for reliability: it runs as a persistent Foreground Service, ensuring your connection stays alive and data keeps flowing even when the screen is off.

🌟KEY FEATURES

📡Professional MQTT Client

•TCP Connection: Connect to any standard MQTT Broker (v3.1.1).

•Custom Configuration: Set Broker IP and Port easily.

•Multi-Topic Subscription: Listen to multiple topics simultaneously.

•Secure & Stable: Auto-reconnection logic and parameter locking during execution.

🔄Advanced UDP Server

•Local Listener: Runs a local UDP server to capture incoming data packets.

•Smart Forwarding: Automatically tracks incoming peers to send replies without manual IP configuration.

•Fixed TX Port (Unique Feature): Option to force outgoing packets to a specific target port (essential for strict hardware devices or asymmetric UDP clients).

🔀Real-Time Bridge (Gateway)

•MQTT ➔ UDP: Incoming MQTT messages are automatically relayed to all active UDP clients.

•UDP ➔ MQTT: Incoming UDP data packets are instantly published to your MQTT topic.

•Live Log: Scrollable console with timestamps for packet inspection and debugging.

✨User Experience

•Interactive Walkthrough: Step-by-step tutorial on first launch to get you started in seconds.

•Dark Mode: Fully supported dark theme for comfortable use in low-light environments.

•Background Service: Keeps sockets open while the app is minimized.

🎯Perfect For:

•Debugging WiFi firmware on ESP32 / ESP8266.

•Bridging Home Assistant with legacy UDP sensors.

•Testing industrial automation protocols on the go.

•Monitoring network traffic between devices.
