Abstract

Systems and methods for a continuous monitoring of analyte values received from an analyte sensor system are provided. One method for a wireless data communication between an analyte sensor system and a mobile device involves storing identification information associated with a transceiver of the analyte sensor system, the identification information entered by a user of the mobile device via a custom application running on the mobile device; causing the custom application to enter a background mode; searching for advertisement signals; receiving an advertisement signal from the transceiver; authenticating the transceiver based on the identification information; prompting the user to bring the custom application to a foreground mode; causing the custom application to request a confirmation from the user that a data connection with the transceiver is desired; receiving the confirmation from the user; and completing the data connection with the transceiver.

Claims

1. A method for a wireless data communication between an analyte sensor system and a plurality of display devices capable of displaying analyte values wirelessly received from the analyte sensor system, the method comprising:

a processor of an analyte sensor system causing transmitting a first series of advertisement signals from a transceiver of the analyte sensor system;

receiving at the transceiver of the analyte sensor system a first data connection request from a transceiver of a first display device;

determining by the processor of the analyte sensor system that the first display device is identified in a first list containing one or more allowed display devices;

establishing by the processor of analyte sensor system a first data connection between the transceiver of the analyte sensor system and the transceiver of the first display device;

receiving a request from the transceiver of the first display device, wherein the request is for identifying the first display device in a second list, and wherein the second list stores information about a currently active display device configured to receive and display analyte values from the analyte sensor system;

responsive to the request, transmitting from the analyte sensor system a first signal to the first display device indicating that the first display device is not identified, and a second display device that is different from the first display device is identified in the second list;

receiving at the analyte sensor system a second signal from the first display device indicating that the first display device is a newly selected active display device;

responsive to the second signal, changing by the processor of the analyte sensor system the second list, wherein the changing to the list includes indicating that the second display device is no longer the active display device, and selecting the first display device as the single currently active display device for receiving and displaying analyte values from the analyte sensor system; and

terminating by the processor of the analyte sensor system the first data connection with the first display device.

2. The method of claim 1, further comprising transmitting a third signal from the analyte sensor system to the first display device indicating that the first display device is the new selected single currently active display device.

3. The method of claim 1, further comprising:

reading from the second list first data identifying the second display device as the currently active display device, wherein the changing comprises replacing the first data with second data identifying the first display device.

4. The method of claim 3, wherein the second signal comprises a request to write to the second list the second data identifying the first display device as the currently active display device.

5. The method of claim 1, further comprising:

transmitting a second series of advertisement signals;

receiving a second data connection request from the first display device;

establishing a second data connection with the first display device;

determining that the first display device is identified in the second list;

transmitting an analyte value to the first display device; and

terminating the second data connection with the first display device.

6. The method of claim 5, further comprising:

transmitting a third series of advertisement signals;

receiving a third data connection request from the second display device;

establishing a third data connection with the second display device if it is determined that the second display device is identified in the first list;

transmitting a fourth signal to the second display indicating that a different display device is identified in the second list;
