Tracking and communicating with short-range communication devices

摘要

First communication circuitry of a first device is made discoverable by a second device via a short-range wireless protocol. A device name for the first communication circuitry is set to a user identifier that is specific to a user of the first device. The second device discovers the first device and the user identifier is transmitted to the second device. A response message can also be included with the user identifier and can be appended to the user identifier. The second device stores the user identifier, and the response message if included, in a log to record a presence of the user of the first device within a range between the first and second devices of the short-range wireless protocol.

主权项

1. A system comprising:
a first device including
first communication circuitry configured to communicate with a second device by a short-range wireless protocol,first control circuitry configured to
activate the first communication circuitry so that the first communication circuitry is detectable by the second device via the short-range wireless protocol, andset a device name for the first communication circuitry to a user identifier that is specific to a user of the first device,a receiver configured to receive a scan signal from the second device via the first communication circuitry and the short-range wireless protocol, anda transmitter configured to transmit the user identifier to the second device via the first communication circuitry and the short-range wireless protocol in response to receiving the scan signal; and the second device including
second communication circuitry configured to communicate with the first device by the short-range wireless protocol, andsecond control circuitry configured to
activate the second communication circuitry to transmit the scan signal to the first device,receive the user identifier of the first communication circuitry of the first device via the second communication circuitry and the short-range wireless protocol in response to the first device receiving the scan signal and transmitting the user identifier to the second device, andstore, in a memory of the second device, the user identifier in a log to record a presence of the user of the first device within a range between the first device and the second device, the range being a range of the short-range wireless protocol.
