The BluetoothAdapterEvent interface of the Bluetooth API provides access to a BluetoothAdapter object and its address as the parameter of a adapteradded or adapterremoved event handler (see BluetoothManager.onadapteradded and BluetoothManager.onadapterremoved), when fired.
no-linkReturns the BluetoothAdapter object. This is null for the BluetoothManager.onadapterremoved event handler since the corresponding adapter is already removed.
no-linkReturns a DOMString representing the address of the removed adapter. The property is null for the BluetoothManager.onadapteradded event handler since the adapter already has an BluetoothAdapter.address property.
