Abstract
A protocol for operation of wireless devices enables a wireless device to remotely and securely invoke a service on a target wireless device without requiring the user of the target wireless device to take any action and without requiring the target wireless device to use power unnecessarily. Mutual authentication is executed while the target wireless device remains in a low power discoverable mode. The discoverable mode includes discovery windows separated by inactive windows when the radio of the target wireless device is powered down.
