BluetoothUUID
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
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
BluetoothUUID.canonicalUUID()-
Returns the 128-bit UUID when passed the 16- or 32-bit UUID alias.
BluetoothUUID.getCharacteristic()-
Returns the 128-bit UUID representing a registered characteristic when passed a name or the 16- or 32-bit UUID alias.
BluetoothUUID.getDescriptor()-
Returns a UUID representing a registered descriptor when passed a name or the 16- or 32-bit UUID alias.
BluetoothUUID.getService()-
Returns a UUID representing a registered service when passed a name or the 16- or 32-bit UUID alias.
Examples
In the following example the UUID representing the service named device_information is returned and printed to the console.
let result = BluetoothUUID.getService("device_information");
console.log(result); // "0000180a-0000-1000-8000-00805f9b34fb"
