Supported Inclination Range (0x2AD5): byte layout
GATT characteristic · org.bluetooth.characteristic.supported_inclination_range · read from the Bluetooth SIG’s repository on 2026-10-17 · commit 408f4a0 (2026-10-14)
Supported Inclination Range is Bluetooth GATT characteristic 0x2AD5, org.bluetooth.characteristic.supported_inclination_range in the Bluetooth SIG's assigned numbers. The SIG's GATT Specification Supplement file lays its value out as 3 fields: Minimum Inclination, Maximum Inclination and Minimum Increment. Every field has a fixed size, 6 octets in all.

org.bluetooth.characteristic.supported_inclination_range- The SIG’s description
- The Supported Inclination Range characteristic is used to represent the inclination range supported by a fitness machine.The structure of this characteristic is defined below.
- Service the SIG’s files tie it to
- None: no file in the repository lists this characteristic under a service.
- Source file
- gss/org.bluetooth.characteristic.supported_inclination_range.yaml
Byte layout: 3 fields
In the order the SIG’s structure lists them. Type and size are as published; sizes count octets except where a struct is marked as sized in bits. The offset is printed only where every earlier field has a fixed size; where an earlier field can be absent or vary, the cell names what it depends on. “Present when” is read from the field’s own “Present if” line, shown in full in the field notes below.
| Offset | Field | Type | Size | Present when | Unit |

| 2 | Maximum Inclination | sint16 | 2 | Always (fixed size) | percentageorg.bluetooth.unit.percentage |
| 4 | Minimum Increment | uint16 | 2 | Always (fixed size) | percentageorg.bluetooth.unit.percentage |

Questions
- What is the UUID of the Supported Inclination Range characteristic?
- 0x2AD5. The Bluetooth SIG's characteristic_uuids.yaml lists Supported Inclination Range as 0x2AD5 with the identifier org.bluetooth.characteristic.supported_inclination_range. No file in the SIG's repository ties it to a service: the repository lists service and characteristic UUIDs separately.
- Are any Supported Inclination Range fields optional?
- No. Every field in the SIG's structure has a size that cannot be zero: Minimum Inclination (sint16, 2), Maximum Inclination (sint16, 2) and Minimum Increment (uint16, 2).
- What units does Supported Inclination Range use?
- The SIG's text names a unit for 3 of the 3 fields: Minimum Inclination: percentage (org.bluetooth.unit.percentage); Maximum Inclination: percentage (org.bluetooth.unit.percentage); Minimum Increment: percentage (org.bluetooth.unit.percentage).
- How many bytes is a Supported Inclination Range value?
- 6 octets. Every field has a fixed size in the SIG's structure: Minimum Inclination at offset 0 (sint16, 2), Maximum Inclination at offset 2 (sint16, 2) and Minimum Increment at offset 4 (uint16, 2).
