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.

First claim

What is claimed is:

1. An analyte sensor system configured for 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 of the plurality of display devices;
receive a second data connection request from a second display device of the plurality of display devices;
determine that the first display device is not identified in the list;
determine that the second display device is identified in the list;
establish a data connection with the second display device; and
reject the first data connection request from the first display device.

2. The analyte sensor system of claim 1 , wherein the processor is further configured to:
engage in data communication with the second display device after establishing the data connection; and
terminate the data connection after completing the data communication, and cause the transceiver to enter a sleep mode.

3. The analyte sensor system of claim 1 , wherein the analyte sensor is a continuous glucose sensor.

4. The analyte sensor system of claim 1 , wherein one of the plurality of display devices is a custom analyte monitoring device and another one of the plurality of display devices is a mobile device.

5. The analyte sensor system of claim 1 , wherein the wireless data communication employs a short-distance and low-power wireless communication protocol.

6. The analyte sensor system of claim 1 , wherein the processor is a link layer (LL) controller.

7. The analyte sensor system of claim 6 , wherein the list is a white list maintained in the LL controller.

8. The analyte sensor system of claim 1 , wherein the processor is further configured to at least one of approve the second data connection request or reject the first data connection request at a radio hardware level.

9. The analyte sensor system of claim 1 , wherein the processor is further configured to clear the list if a predetermined condition is met.

10. The analyte sensor system of claim 9 , wherein the processor is further configured to:
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.

11. The analyte sensor system of claim 9 , 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.

12. The analyte sensor system of claim 9 , 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.

13. A method of wireless data communication between an analyte sensor system configured 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 of the plurality of display devices;
receiving a second data connection requests from a second display device of the plurality of display devices
determining that the first display device is not identified in a list stored at the analyte sensor system, the list identifying a single allowed display device;
determining that the second display device is identified in the list;
establishing a data connection with the second display device; and
rejecting the first data connection request from the first display device.

14. The method of claim 13 , further comprising:
engaging in data communication with the second display device after establishing the data connection; and
terminating the data connection after completing the data communication, and entering a sleep mode.

15. The method of claim 13 , wherein at least one of the determining that the second display device is identified in the list or rejecting the first data connection request is performed at a radio hardware level.

16. The method of claim 13 , further comprising clearing the list if a predetermined condition is met.

17. The method of claim 16 , further comprising:
determining that the list has been cleared;
granting the second data connection request; and
writing data identifying the second display device in the list.

18. The method of claim 16 , 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.

19. The method of claim 16 , 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.
