src.bluetooth_sig.gatt.characteristics.enhanced_intermediate_cuff_pressure¶

Enhanced Intermediate Cuff Pressure characteristic implementation.

Implements the Enhanced Intermediate Cuff Pressure characteristic (0x2B35). Reports a single intermediate cuff pressure reading (medfloat16) during an ongoing measurement, with enhanced optional fields matching the Enhanced Blood Pressure Measurement pattern.

Flag-bit assignments (from GSS YAML):: Bit 0: Units (0=mmHg, 1=kPa) Bit 1: Time Stamp present (uint32 seconds since epoch) Bit 2: Pulse Rate present (medfloat16) Bit 3: User ID present (uint8) Bit 4: Measurement Status present (boolean[16]) Bit 5: User Facing Time present (uint32 seconds since epoch) Bit 6: Epoch Start 2000 (0=1900, 1=2000) Bit 7: Reserved
