The Samsung Health Accessory SDK defines Bluetooth Low Energy (BLE) compatible guidelines and Samsung Health specifications based on Bluetooth Generic Attributes (GATT), including service structure, to connect with Samsung Health.
BLE compatible guidelines include data communication flows defined in BLE standard specifications required by Samsung Health.
Through a wide variety of compatible health devices, users can sync data related to blood glucose levels, blood pressure, heart rate, weight, temperature, cycling power, and cycling speed and cadence with Samsung Health.
Additionally, Samsung Health provides data flows and specifications for upcoming supported services, including pedometers and exercise and sleep monitors, which are not covered in standard BLE specs.
These standards are set forth in a similar structure to BLE standard specs, allowing device vendors to easily adapt to the specifications.

You can access the Samsung Health Accessory SDK and documentation here.

Samsung Health specifications defined by Accessory SDK are based on the Bluetooth® specifications, but there are some differences, so see here for details.

To ensure compliance with Samsung Health specifications, we have developed the Samsung Health Compliance Verification Tool. This tool allows developers to :

1.Validate device behavior against Samsung Health requirements (such as data format and protocol adherence),
2.Diagnose implementation gaps through automated test reports and error logs. By integrating this tool into your development workflow, you can proactively identify and resolve compatibility issues, ensuring seamless interoperability with the Samsung Health ecosystem.

More information about the Verification Tool is available here.

To verify your device with the Verification Tool (VT), refer to the VT User Guide for detailed implementation procedures.

Samsung Health is an application to provide insight through various health indicators and acquire health information from health devices.
SmartThings is an application to help user to connect, monitor, and control multiple smart home devices.
Samsung Health devices can quickly and easily be onboarded on SmartThings. After onboarding, Samsung Health can connect to the device automatically for use.
The SmartThings Support Specification provides Samsung Health guidelines for health devices to support the interworking between Samsung Health and SmartThings. It includes the recommended specification and communication flow.

You can access SmartThings Support Specification refer to here.

No, these methods are optional. They are intended to provide users with a more convenient onboarding experience.

The SmartThings Support Specification focuses on device onboarding, enabling devices to be scanned, registered, and managed within the ST, after which device information can be synchronized to the Health application. The Accessory SDK, on the other hand, defines data interaction protocols between devices and the Health application, standardizing data formats (such as sensor readings and commands) and facilitating real-time communication. Together, they ensure device-to-device functionality: the SmartThings Support Specification handles device management, while the Accessory SDK governs post-connection data flow. Developers must integrate both SDKs to achieve seamless device integration and reliable data exchange.

Yes, all future health devices will only support onboarding through the ST platform. This is intended to provide a unified user experience without requiring users to distinguish between health devices and other categories of equipment.
