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:

storing a first list identifying bonding information associated with the plurality of display devices, the bonding information generated during initial pairing of each of the display devices with a transceiver, and a second list identifying whether bonded display devices are allowed to establish data connections with the transceiver, wherein by utilizing the second list, data connection requests from each of the display devices can be rejected or granted promptly at a radio hardware level;

transmitting a first series of advertisement signals;

receiving a first data connection request from a first display device of the plurality of display devices in response to the first series of advertisement signals;

rejecting the first data connection request from the first display device at the radio hardware level when the first display device is identified in the first list but not in the second list indicating that the first display device had previously paired with the transceiver, but not allowed to establish data communication with the transceiver,

receiving a second data connection request from a second display device of the plurality of display devices responsive to the first series of advertisement signals, and

granting the second data connection request at the radio hardware level when the second display device is identified both in the first and second lists indicating that the second display device had previously paired with the transceiver, and also allowed to establish data communication with the transceiver.

2. The method of claim 1, comprising generating sensor data using the analyte sensor system.

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

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

5. 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.

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

7. The method of claim 6, further comprising:

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

determining that the second list has been cleared and the bonding information associated with the first display device is in the first list;

granting the third data connection request; and

writing data identifying the first display device in the second list.

8. The method of claim 6, wherein the predetermined condition is reception of a clearance signal from the second display device identified in the second list indicating that the listed display device is to be cleared from the second list.

9. The method of claim 6, wherein the predetermined condition is a failure to receive a data connection request from the second display device identified in the second list within a predetermined number of communication sessions.

10. 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 configured to generate sensor data;

a transceiver configured to transmit and receive wireless signals to connect with the plurality of display devices including a first and a second display device;

a memory for storing;

a first list identifying bonding information associated with the plurality of display devices, the bonding information generated during initial pairing of each of the display devices with the transceiver,

a second list identifying whether bonded display devices are allowed to establish data connections with the transceiver, wherein by utilizing the second list, data connection requests from each of the display devices can be rejected or granted promptly at a radio hardware level, 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,

responsive to the first series of advertisement signals, receive a first data connection request from the first display device,

reject the first data connection request from the first display device at a radio hardware level when the first display device is identified in the first list but not in the second list indicating that the first display device had previously paired with the transceiver, but not allowed to establish data communication with the transceiver,

receive a second data connection request from the second display device responsive to the first series of advertisement signals, and

grant the second data connection request at the radio hardware level when the second display device is identified both in the first and second lists indicating that the second display device had previously paired with the transceiver, and also allowed to establish data communication with the transceiver.

11. The analyte sensor system of claim 10, wherein the analyte sensor is configured to generate sensor data.

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

exchange the sensor data with the second display device after establishing the data connection,

terminate the data connection after completing the exchange of the sensor data, and

cause the transceiver to enter a sleep mode.

13. The analyte sensor system of claim 10, wherein the processor is further configured to clear the second list if a predetermined condition is met.

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

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

determine that the second list has been cleared and the bonding information associated with the first display device is in the first list,

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

write data identifying the first display device in the second list.

15. The analyte sensor system of claim 13, wherein the predetermined condition includes a reception of a clearance signal from the second display device identified in the list indicating that the listed display device is to be cleared from the second list.
