src.bluetooth_sig.gatt.characteristics.templates.domain¶

Domain-specific templates that compose scaled templates.

Covers TemperatureTemplate, ConcentrationTemplate, PressureTemplate.

Classes¶

Name	Description
`ConcentrationTemplate`	Template for concentration measurements with configurable resolution.
`PressureTemplate`	Template for pressure measurements (uint32, 0.1 Pa resolution).
`TemperatureTemplate`	Template for standard Bluetooth SIG temperature format (sint16, 0.01°C resolution).

class src.bluetooth_sig.gatt.characteristics.templates.domain.ConcentrationTemplate(resolution: float = 1.0)¶

Template for concentration measurements with configurable resolution.

Used for environmental sensors like CO2, VOC, particulate matter, etc.

decode_value(data: bytearray, offset: int = 0, ctx: src.bluetooth_sig.gatt.context.CharacteristicContext | None = None, *, validate: bool = True) → float¶: Parse concentration with resolution.

encode_value(value: float, *, validate: bool = True) → bytearray¶: Encode concentration value to bytes.

classmethod from_letter_method(M: int, d: int, b: int = 0) → ConcentrationTemplate¶

Create instance using Bluetooth SIG M, d, b parameters.

Parameters:

Returns:

ConcentrationTemplate instance

property data_size: int¶

2 bytes.

property extractor: src.bluetooth_sig.gatt.characteristics.utils.extractors.RawExtractor¶: Get extractor from underlying scaled template.

property translator: src.bluetooth_sig.gatt.characteristics.utils.translators.ValueTranslator[float]¶: Return the linear translator from the underlying scaled template.

class src.bluetooth_sig.gatt.characteristics.templates.domain.PressureTemplate¶

Template for pressure measurements (uint32, 0.1 Pa resolution).

decode_value(data: bytearray, offset: int = 0, ctx: src.bluetooth_sig.gatt.context.CharacteristicContext | None = None, *, validate: bool = True) → float¶: Parse pressure in 0.1 Pa resolution (returns Pa).
