BluetoothUUID
The BluetoothUUID
interface of the Web Bluetooth API
provides a way to look up Universally Unique Identifier (UUID) values by name in the
registry maintained by the Bluetooth SIG.
Description
A UUID string is a 128-bit UUID, for example 00001818-0000-1000-8000-00805f9b34fb
.
The Bluetooth registry contains lists of descriptors, services, and characteristics identified by these UUIDs in addition to a 16- or 32- bit alias, and a name.
The BluetoothUUID
interface provides methods to retrieve these 128-bit UUIDs.
Static methods
