Bluetooth Broadcast → MQTT, Easily Build a Soft Gateway This app turns your iOS device into a powerful Bluetooth gateway and debugging tool. It automatically captures broadcast data from surrounding Bluetooth devices, parses it according to custom or known protocols, and publishes the data via MQTT to your server or cloud platform. Core Features Broadcast Capture – Scan and receive broadcast packets from all detectable Bluetooth devices (e.g., beacons, sensors, IoT devices). MQTT Forwarding – Publish raw or parsed data to any MQTT Broker (supports TLS authentication and username/password). Protocol Parsing – Built-in common Bluetooth broadcast protocols (HW80x Heart Rate Armband, ZY Series Wristbands etc.) for automatic parsing and structured output. Debugging Tool – View raw broadcast data in real time (Hex/ASCII), with filtering, packet capture, and log export – ideal for Bluetooth device development and debugging. Soft Gateway Mode – Run continuously in the background (with proper authorization) to forward captured data to the cloud – no additional hardware gateway required. Use Cases Collect and upload Bluetooth device data in smart homes or industrial IoT. Verify and debug broadcast protocols during Bluetooth device development. Quickly prototype and test the Bluetooth → MQTT data link. Privacy & Permissions Bluetooth permission is needed for device scanning. Network permission is required for connecting to an MQTT Broker. No personally identifiable information is collected. All data is controlled by the user, stored and forwarded to the user’s own destination. Requirements iOS 13+ or iPadOS 13+ Device with Bluetooth 4.0+ You must configure your own MQTT Broker address and subscription rules Whether you are an IoT developer, a hobbyist, or a system integrator, this app allows you to achieve cloud connectivity for Bluetooth data at the lowest cost.
