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 mobile device capable of wirelessly receiving analyte values from the analyte sensor system, the method comprising:

transmitting, by a transceiver of the analyte sensor system, a first series of advertisement signals generated by the analyte sensor system beginning at a first time;

receiving, by a processor of the analyte sensor system via the transceiver, a data connection request from a mobile device at a second time;

establishing, utilizing the transceiver under control of the processor, a data connection with the mobile device;

transmitting, by the transceiver, a connection interval indicative of a difference between the second time and the first time to the mobile device;

transmitting, by the transceiver, an analyte value to the mobile device;

terminating, by the transceiver under control of the processor, the data connection with the mobile device; and

causing, utilizing the processor, the transceiver to enter a sleep state.

2. The method of claim 1 further comprising:

causing, utilizing the processor, the transceiver to exit the sleep mode after a predetermined time; and

transmitting, by the transceiver, a second series of advertisement signals.

3. The method of claim 1, wherein the predetermined time is between about 200 and 400 seconds.

4. The method of claim 1, wherein the analyte value is based on an analyte measurement taken by a sensor of the analyte sensor system while the transceiver was in a previous sleep mode.

5. A method for a wireless data communication between an analyte sensor system and a mobile device, the method comprising:

searching, utilizing a transceiver of the mobile device under control of a processor of the mobile device, for advertisement signals generated by the analyte sensor system;

receiving, by the processor via the transceiver, an advertisement signal from a second transceiver of the analyte sensor system;

transmitting, by the transceiver, a data connection request to the second transceiver;

establishing, utilizing the transceiver under the control of the processor, a data connection with the second transceiver if the data connection request is granted;

receiving, by the processor via the transceiver, from the analyte sensor system a connection interval indicative of a difference between a first time at which the second transceiver started to transmit a series of advertisement signals and a second time at which the second transceiver received the data connection request from the mobile device;

receiving, by the processor via the transceiver, an analyte value from the second transceiver;

terminating, by the transceiver under the control of the processor, the data connection with the second transceiver, thereby causing the second transceiver to enter a sleep mode;

causing, utilizing the processor, the transceiver to enter an inactive mode during which the mobile device does not communicate with the second transceiver;

calculating, utilizing the processor, an exit time at which the transceiver is to exit the inactive mode based at least partly on the connection interval;

causing, utilizing the processor, the transceiver to exit the inactive mode at the exit time; and

searching, utilizing the transceiver under the control of the processor, for advertisement signals generated by the analyte sensor system after exiting the inactive mode.

6. The method of claim 5, wherein the analyte value is based on an analyte measurement taken by a sensor of the analyte sensor system while the second transceiver was in a previous sleep mode.

7. The method of claim 5, wherein the processor is configured to calculate the exit time according to the following expression:

current time+update interval−

the connection interval−

notification delay−

safeguard,

further wherein the update interval is a time duration between two consecutive wireless communication sessions between the transceiver and the second transceiver.
