 ##### The `stopAdvertising()` method
 Requests the platform to stop sending advertisement packets. It runs the following steps:
-- Return a [`Promise`](../README.md/#promise) object `promise` and continue [in parallel](https://html.spec.whatwg.org/#in-parallel).
 - Request from the underlying platform to stop the current advertisement.
-- If the request is unsuccessful, reject `promise` with an [`Error`](../README.md/#error) object `error` with `error.message` set to `"BluetoothStopAdvertisement"`.
-- Otherwise, if the request was successful, resolve `promise`.
+- If the request is unsuccessful, throw an [`Error`](../README.md/#error) object `error` with `error.message` set to `"BluetoothStopAdvertisement"`.
