class src.bluetooth_sig.gatt.characteristics.glucose_measurement_context.GlucoseMeasurementContextCharacteristic¶

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

Glucose Measurement Context characteristic (0x2A34).

Used to transmit additional context for glucose measurements including carbohydrate intake, exercise, medication, and HbA1c information.

SIG Specification Pattern: This characteristic depends on Glucose Measurement (0x2A18) for sequence number matching. The sequence_number field in this context must match the sequence_number from a corresponding Glucose Measurement characteristic.

min_length: int | None = 3¶

class src.bluetooth_sig.gatt.characteristics.glucose_measurement_context.GlucoseMeasurementContextData¶

Bases: msgspec.Struct

Parsed data from Glucose Measurement Context characteristic.

Used for both parsing and encoding - None values represent optional fields.
