Tracking and communicating with short-range communication devices

The system according to 2, wherein the second control circuitry of the second device is configured to:

• display, on a display of the second device, a graphical user interface for a user of the second device to log into the second device to activate the inquiry scan and to access registration records that include a list of expected users that are expected to be detected via the inquiry scan,
• compare the received user identifiers with the list of expected users,
• generate a status of the expected users in responding to the inquiry, and
• record, in the memory of the second device, the status of the expected users in the log.

The system according to 1, wherein the second control circuitry of the second device is configured to:

• access a registration database of a course;
• download registration records for the course from a remote server;
• display a list of students enrolled in the course;
• and
• display the list of students enrolled in the course together with an indication correlating the user identifier received form the first device with a student listed in the list of students enrolled in the course together with the response from the respective user.

A slave device comprising:

• communication circuitry configured to communicate with a master device by a short-range wireless protocol;
• and
• control circuitry configured to:
• activate the communication circuitry so that the communication circuitry is detectable by the master device via the short-range wireless protocol,
• set a device name for the communication circuitry to a user identifier that is specific to a user of the slave device and a response to an inquiry,
• receive a scan signal from the master device via the communication circuitry and the short-range wireless protocol, and
• transmit the device name, which includes the user identifier and the response, to the second device via the communication circuitry and the short-range wireless protocol in response to receiving the scan signal.

A method, comprising:

• activating first communication circuitry of a first device so that the first communication circuitry is detectable by a second device via a short-range wireless protocol;
• setting a device name for the first communication circuitry to a user identifier that is specific to a user of the first device and a response to an inquiry;
• activating second communication circuitry of the second device and transmitting a scan signal from the second communication circuitry to the first device via the short-range wireless protocol;
• receiving the scan signal from the second device at the first communication circuitry via the short-range wireless protocol;
• transmitting the device name, which includes the user identifier and the response, from the first communication circuitry to the second device via the short-range wireless protocol in response to the receiving the scan signal;
• receiving the user identifier of the first communication circuitry of the first device and the response at the second communication circuitry via the short-range wireless protocol in response to the first device receiving the scan signal and transmitting the user identifier and the response to the second device;
• and
• storing, in memory circuitry of the second device, the user identifier and the response 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.
