class src.bluetooth_sig.gatt.characteristics.utils.ieee11073_parser.IEEE11073Parser¶

Utility class for IEEE-11073 medical device format support.

static encode_float32(value: float) → bytearray¶: Encode float to IEEE 11073 32-bit FLOAT.

static encode_sfloat(value: float) → bytearray¶: Encode float to IEEE 11073 16-bit SFLOAT.

static encode_timestamp(timestamp: datetime.datetime) → bytearray¶: Encode timestamp to IEEE-11073 7-byte format.

static parse_float32(data: bytes | bytearray, offset: int = 0) → float¶: Parse IEEE 11073 32-bit FLOAT.

static parse_sfloat(data: bytes | bytearray, offset: int = 0) → float¶

Parse IEEE 11073 16-bit SFLOAT.

Parameters:

data – Raw bytes/bytearray
offset – Offset in the data

static parse_timestamp(data: bytearray, offset: int) → datetime.datetime¶: Parse IEEE-11073 timestamp format (7 bytes).
