Use Cases and Integration Notes

BLE Telemetry

Map characteristic values into dashboards and alerts for device observability.

Firmware Regression

Compare decoded fields across builds to detect protocol or scaling changes.

App Integration

Build stable parsing paths that convert raw payloads into typed app models.

Implementation Checklist

  • Validate payload length and mandatory fields before decode.
  • Decode with Bluetooth-specified signedness, unit, and exponent handling.
  • Convert units at presentation boundaries to avoid drift in business logic.
  • Persist raw packets and decoded values for reproducible troubleshooting.
