    Methods

    • The addEventListener() method of the EventTarget interface sets up a function that will be called whenever the specified event is delivered to the target.

      MDN Reference

      Parameters

      • type: string
      • callback: EventListenerOrEventListenerObject | null
      • Optionaloptions: boolean | AddEventListenerOptions

      Returns void

    • Connects to a remote device.

      Parameters

      • address: string

        The address of the remote device.

      Returns Promise<void>
