src.bluetooth_sig.gatt.characteristics.blood_pressure_record¶

Blood Pressure Record characteristic implementation.

Implements the Blood Pressure Record characteristic (0x2B36). This is a segmented record container that wraps another characteristic value identified by a 16-bit UUID.

Structure (from GSS YAML):

Segmentation Header (1 byte):: Bit 0: First Segment Bit 1: Last Segment Bits 2-7: Rolling Segment Counter (0-63)

Sequence Number (uint16) UUID (uint16) – identifies the recorded characteristic Recorded Characteristic (variable) – raw bytes of the inner characteristic E2E-CRC (uint16, optional) – presence defined by service

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

Blood Pressure Record characteristic (0x2B36).

A segmented record container that wraps another characteristic value. The inner characteristic is identified by the UUID field and its raw bytes are stored in recorded_data.
