Bluetooth GATT Characteristic Reference
Object Name (0x2ABE)
Object Name is defined in the Bluetooth GATT XML specification with type org.bluetooth.characteristic.object_name and UUID 0x2ABE.
Quick Summary
Payload length is profile-defined or variable based on field formats. This page is generated from official GATT XML and presented as implementation-ready guidance.
At a Glance
Key reference details for BLE implementation, interoperability testing, and AI-assisted troubleshooting.
| Property | Value |
|---|---|
| Name | Object Name |
| UUID | 0x2ABE |
| Type | org.bluetooth.characteristic.object_name |
| XML Root | Characteristic |
| Source File | org.bluetooth.characteristic.object_name.xml |
| Field Count | 1 |
Field Specification
Parsed field definitions from the source XML value structure.
| Field | Requirement | Format | Unit | Exponent | Notes |
|---|---|---|---|---|---|
| Object Name | Mandatory | utf8s | - | 0 | The length of the field value is variable from 0 octets to 120 octets. |
Byte Layout and Decode
Payload length is profile-defined or variable based on field formats.
function decodePayload(dataView, offset = 0) {
// Parse object_name (utf8s) according to Bluetooth format rules.
return { object_name };
}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.
