Use Cases and Integration Notes
Service Discovery
Use this definition to validate discovered services and expected characteristics during BLE onboarding.
Profile Compliance
Cross-check required characteristics and properties for conformance and QA automation.
App Capability Gating
Drive feature availability in apps based on whether service-level requirements are present.
Implementation Checklist
- Validate the service UUID during discovery before reading characteristic metadata.
- Ensure mandatory characteristics exist and expose expected properties.
- Map declaration data to app feature flags before attempting writes/subscriptions.
- Record mismatches between firmware tables and expected profile definitions in logs.
