Bluetooth GATT Characteristic Reference
Supported Resistance Level Range (0x2AD6)
The Supported Resistance Level Range characteristic is used to send the supported resistance level range as well as the minimum resistance increment supported by the Server.
Quick Summary
Payload length is 6 bytes. This page is generated from official GATT XML and presented as implementation-ready guidance.

Field Specification
Parsed field definitions from the source XML value structure.
| Field | Requirement | Format | Unit | Exponent | Notes |
|---|---|---|---|---|---|
| Minimum Resistance Level | Mandatory | sint16 | org.bluetooth.unit.unitless | -1 | Unitless with a resolution of 0.1 |
| Maximum Resistance Level | Mandatory | sint16 | org.bluetooth.unit.unitless | -1 | Unitless with a resolution of 0.1 |
| Minimum Increment | Mandatory | uint16 | org.bluetooth.unit.unitless | -1 | Unitless with a resolution of 0.1 |
Byte Layout and Decode
Payload length is 6 bytes.
function decodePayload(dataView, offset = 0) {
const minimum_resistance_level = dataView.getInt16(offset + 0, true);
const maximum_resistance_level = dataView.getInt16(offset + 2, true);
const minimum_increment = dataView.getUint16(offset + 4, true);
return { minimum_resistance_level, maximum_resistance_level, minimum_increment };
}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.
