Bluetooth.referringDevice Read only
Returns a reference to the device, if any, from which the user opened the current page. For example, an Eddystone beacon might advertise a URL, which the user agent allows the user to open. A BluetoothDevice representing the beacon would be available through navigator.bluetooth.referringDevice.


An event handler that runs when an event of type availabilitychanged has fired.

Returns a Promise that resolved to an array of BluetoothDevices which the origin already obtained permission for via a call to Bluetooth.requestDevice().
Returns a Promise to a BluetoothDevice object with the specified options.
