MQTT BLE Bridge

Bridge the gap between MQTT message brokers and Bluetooth Low Energy devices with this powerful connectivity app.

KEY FEATURES:

• Connect to any MQTT broker with authentication support
• Scan and pair with Bluetooth Low Energy (BLE) devices
• Bidirectional message forwarding between MQTT and BLE
• Background operation keeps connections alive
• Auto-reconnect for reliable communication
• Real-time connection status monitoring
• Configurable topics and device characteristics

New in 1.2.0

• Browse and add topics from a labeled catalog instead of typing MQTT paths
• Topics are grouped by region (e.g. Maui, Columbia) for easier picking
• Friendly topic names show throughout the app
• Optional badges on catalog entries highlight topic types at a glance
• Refresh the topic list from your device’s catalog URL

PERFECT FOR:

• IoT developers and enthusiasts
• Home automation projects
• Remote sensor monitoring
• Industrial IoT applications
• Bluetooth device integration
• MQTT-based systems

HOW IT WORKS:

The app creates a seamless bridge between two protocols - receive MQTT messages and forward them to your Bluetooth device, or send Bluetooth data to your MQTT broker. Perfect for connecting legacy BLE devices to modern IoT platforms.

TECHNICAL FEATURES:

• Supports custom service and characteristic UUIDs
• Persistent connection settings
• Message logging and debugging
• Cross-platform compatibility
• Battery optimization support

Transform your Bluetooth devices into MQTT-enabled IoT endpoints effortlessly.
