Bluetooth: availabilitychanged event

The availabilitychanged event fires when the Bluetooth system as a whole becomes available or unavailable to the User Agent.

Use the event name in methods like addEventListener(), or set an event handler property.

addEventListener('availabilitychanged', event => { });

onavailabilitychanged = event => { };

A generic Event.

To be informed when Bluetooth availability changes, you can add a handler to your Bluetooth instance using addEventListener(), like this:

Bluetooth.addEventListener("availabilitychanged", function(event) {
  var availability = event.value;
});

Alternatively, you can use the Bluetooth.onavailabilitychanged event handler property to establish a handler for the availabilitychanged event:

Bluetooth.onavailabilitychanged = function(event) {
 var availability = event.value;
}
