//| .. currentmodule:: bleio
//|
//| :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`
//|
