//| :class:`UUID` -- BLE UUID
|
|
//| =========================================================
|
|
//|
|
|
//| Encapsulates both 16-bit and 128-bit UUIDs. Can be used for services,
|
|
//| characteristics, descriptors and more.
|
|
//|
|
|
|
|
//| .. class:: UUID(uuid)
|
|
//|
|
|
//| Create a new UUID object encapsulating the uuid value.
|
|
//| The value itself can be one of:
|
|
//|
|
|
//| - a `int` value in range of 0 to 0xFFFF
|
|
//| - a `str` value in the format of '0xXXXX' for 16-bit or 'XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX' for 128-bit
|
|
//|
|
|
//| :param int/str uuid: The uuid to encapsulate
|
|
//|
|
|
|
|
//| .. method:: __len__()
|
|
//|
|
|
//| Returns the uuid length in bits
|
|
//|
|
|
//| This allows you to:
|
|
//|
|
|
//| uuid = bleio.UUID(0x1801)
|
|
//| print(len(uuid))
|
|
//|
|
|
|
|
//| .. attribute:: type
|
|
//|
|
|
//| The UUID type. One of:
|
|
//|
|
|
//| - `bleio.UUIDType.TYPE_16BIT`
|
|
//| - `bleio.UUIDType.TYPE_128BIT`
|
