This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

The BluetoothGattService interface of the Web Bluetooth API represents a service provided by a GATT server, including a device, a list of referenced services, and a list of the characteristics of this service.

This page describes the W3C Community Group BluetoothGATTService. For the Firefox OS interface of the same name, see BluetoothGattService.
