bluetoazure

bluetoazure is a software framework designed to bridge Bluetooth devices and the Microsoft Azure cloud platform. It provides a set of tools and runtimes intended for developers building Internet of Things (IoT) solutions that rely on Bluetooth Low Energy or Bluetooth Classic devices while leveraging Azure services for device management, data ingestion, and analytics.

Architecture and components: The framework centers on an edge gateway that runs on supported hardware such as single-board computers or industrial gateways, a device software development kit for provisioning and data encoding, and cloud connectors that forward messages to Azure IoT Hub or Azure Event Hubs. The gateway handles device discovery, GATT interactions, and local buffering, while the cloud connectors translate Bluetooth payloads into Azure-compatible telemetry, typically in JSON or CBOR, using protocols such as MQTT over TLS or AMQP. A provisioning workflow allows devices to be enrolled and assigned to an IoT hub, with device twins and desired property updates available in the cloud.

Security and data governance: bluetoazure emphasizes secure identity and communications, supporting per-device authentication via Azure IoT Hub’s provisioning service, mutual TLS, and role-based access control. Data integrity and privacy are served by encrypted transport, configurable message schemas, and audit logging for device actions and gateway activity.

Development status and licensing: The project is open-source and released under a permissive license, with reference implementations for common gateway platforms and programming languages. Ongoing work focuses on expanding platform support, improving payload adapters, and integrating additional Azure services such as Stream Analytics, Functions, and Logic Apps.

Use cases and scope: Potential applications include industrial asset tracking, smart buildings, and healthcare device integration, enabling real-time monitoring and analytics while leveraging Azure orchestration and storage. bluetoazure is best suited for environments already invested in Azure and needing scalable Bluetooth device connectivity.
