class src.bluetooth_sig.gatt.characteristics.chromaticity_in_cct_and_duv_values.ChromaticityInCCTAndDuvData¶

Bases: msgspec.Struct

Data class for Chromaticity in CCT and Duv Values.

Combines Correlated Color Temperature (Kelvin) with Chromatic Distance from Planckian (unitless Duv).

Bases: src.bluetooth_sig.gatt.characteristics.base.BaseCharacteristic[ChromaticityInCCTAndDuvData]

Chromaticity in CCT and Duv Values characteristic (0x2AE5).

org.bluetooth.characteristic.chromaticity_in_cct_and_duv_values

Combines Correlated Color Temperature and Chromatic Distance from Planckian into a single composite characteristic.

Field 1: CCT — uint16, raw Kelvin (references Correlated Color Temperature). Field 2: Duv — sint16, M=1 d=-5 b=0 (references Chromatic Distance From Planckian).
