Bluetooth GATT Characteristic Reference
HTTP Control Point (0x2ABA)
The HTTP Control Point is used to initiate a request to send an HTTP request message from the device contgaining the HTTP Proxy Service, acting as an HTTP Client, and an HTTP Server.

}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.
