Summary
The isConnected method is used to check if a device with a given Bluetooth profile is connected.
This is particularly helpful if a device has been connected using the BluetoothAdapter.connect() method without its second parameter. Because the supported Bluetooth profiles are platform dependent, it is sometimes necessary to check if a given Bluetooth profile is usable.
Syntax
var request = instanceOfBluetoothAdapter.isConnected(serviceUuid);
Parameters
serviceUuid- A number representing a UUID of Bluetooth service.
Returns
A DOMRequest object to handle the success or error of the operation.
Specification
Not part of any specification yet. It should be discussed as part of the W3C's System Applications Working Group.
