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:

transmitting a first series of advertisement signals;

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

determining whether the first display device is identified in a list for containing a single allowed display device; and

rejecting the first data connection request from the first display device at a radio hardware level if the first display device is not identified in the list.

2. The method of claim 1, further comprising granting the first data connection request from the first display device at the radio hardware level if the first display device is identified in the list.

3. The method of claim 1, further comprising establishing a first data connection with the first display device and transmitting an analyte value to the first display device.

4. The method of claim 3, wherein the analyte value is indicative a blood glucose value.

5. The method of claim 1, wherein information identifying one or more display devices that have been paired with the transceiver is also stored in the list.

6. The method of claim 1, wherein information identifying one or more display devices that have been paired with the transceiver is stored in a different list.

7. The method of claim 1, further comprising continuing to accept data connection requests from one or more display devices when no other display device has been paired with the analyte sensor system.

8. The method of claim 1, further comprising clearing the list if a predetermined condition is met.

9. The method of claim 8, wherein the predetermined condition is a failure to receive a data connection request from a listed display device identified in the list within a predetermined number of communication sessions.

10. The method of claim 8, wherein the predetermined condition is reception of a clearance signal from a listed display device identified in the list indicating that the listed display device is to be cleared from the list.

11. The method of claim 8, further comprising:

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

determining that the list has been cleared;

granting the second data connection request; and

writing data identifying the second display device in the list.

12. An analyte sensor system configured for a wireless data communication with a plurality of display devices capable of displaying analyte values wirelessly received from the analyte sensor system, the analyte sensor system comprising:

an analyte sensor;

a memory for storing a list identifying a single allowed display device;

a transceiver configured to transmit and receive wireless signals; and

a processor operatively coupled to the analyte sensor, the memory, and the transceiver and configured to;

cause the transceiver to transmit a first series of advertisement signals,

receive a first data connection request from a first display device,

determine that the first display device is not identified in the list, and

reject the data connection request from the first display device at a radio hardware level.

13. The analyte sensor system of claim 12, wherein the processor is further configured to:

cause the transceiver to continue transmitting one or more advertisement signals after rejecting the first data connection request,

receive a data connection request from a second display device, and

establish a data connection with the second display device if the second display device is identified in the list.

14. The analyte sensor system of claim 13, wherein the processor is further configured to:

engage in data communication with the second display device after establishing the data connection,

terminate the data connection after completing the data communication, and

cause the transceiver to enter a sleep mode.

15. The analyte sensor system of claim 12, wherein the processor is further configured to clear the list if a predetermined condition is met.

16. The analyte sensor system of claim 15, wherein the predetermined condition includes a failure to receive a data connection request from a listed display device identified in the list within a predetermined number of communication sessions.

17. The analyte sensor system of claim 15, wherein the predetermined condition includes a reception of a clearance signal from a listed display device identified in the list indicating that the listed display device is to be cleared from the list.

18. The analyte sensor system of claim 15, wherein the processor is further configured to:

receive a second data connection request from a second display device,

determine that the list has been cleared,

cause the transceiver to grant the second data connection request, and

write data identifying the second display device in the list.
