Abstract
A first device including a transmitter, a receiver, and a processor. The transmitter is configured to wirelessly transmit a query to a second device that is remote from the first device. The query is configured to not generate an alert to a user of the second device in response to the second device receiving the query. The receiver is configured to wirelessly receive data from the second device in response to the query transmitted to the second device. The data indicates whether the second device is (i) busy and cannot currently communicate with the first device or (ii) not busy and can currently communicate with the first device. The processor is configured to determine, based on whether the second device is (i) busy and cannot currently communicate with the first device or (ii) not busy and can currently communicate with the first device, whether to communicate with the second device.
