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.
BluetoothUUID
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.
Properties
None.
Event handlers
None.
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"
