Abstract

Systems, devices, and methods are disclosed for wireless communication of analyte data. In this regard, in embodiments, a mobile includes a transceiver configured to transmit and receive wireless signals. The mobile device includes circuitry operatively coupled to the transceiver. The mobile device also includes a non-transitory computer-readable medium operatively coupled to the circuitry and storing instructions that, when executed, cause the mobile device to perform a number of operations. One such operation is to obtain a derivative of a first signal received via a first link. Another such operation is to obtain a derivative of a second signal received via a second link; and. Yet another such operation is to generate a selection for connection to an analyte sensor system, based on a comparison of the derivative of the first signal and the derivative of the second signal.

First claim

What is claimed is:

1. A method for wireless communication of analyte data, the method comprising:
generating analyte measurements indicative of analyte concentrations in a host using a transcutaneous analyte sensor of an analyte sensor system;
processing the analyte measurements using a sensor electronics module integral with, or releasably attachable to, the transcutaneous analyte sensor to generate analyte data;
authenticating a first display device for a first wireless connection by exchanging information related to authentication between the analyte sensor system and the first display device;
upon authenticating the first display device, the analyte sensor system periodically exchanging messaging with the first display device to maintain the first wireless connection;
encrypting the analyte data to generate encrypted analyte data, wherein the analyte data includes glucose data; and
the analyte sensor system transmitting the encrypted analyte data to the first display device during a time the first wireless connection is maintained, wherein the first display device displays at least some of the information associated with the analyte data and alarms the host using an alarm mechanism located on the first display device.

2. The method of claim 1 , the first display device is configured to process the encrypted analyte data and display the analyte data.

3. The method of claim 1 , wherein:
the analyte sensor system is in a storage mode before it is inserted into the host,
a radio and a processor of the analyte sensor system are at least partially disabled when the analyte sensor system is in the storage mode, and
the analyte sensor system exits the storage mode upon interacting with the first display device via NFC.

4. The method of claim 1 , wherein a second display device not connected to the analyte sensor system receives at least a portion of analyte data via the first display device.

5. The method of claim 4 , wherein the first display device is permitted to transmit the portion of the analyte data to the second display device only upon the authenticating being successful.

6. The method of claim 4 , wherein:
the first display device connects to the analyte sensor system using a first wireless communication protocol, and
the first display device further connects to a second display device using a second wireless communication protocol.

7. The method of claim 4 , wherein:
the first display device connects to the analyte sensor system using a first wireless communication protocol that is Bluetooth Low Energy (BLE), and
the first display device further connects to a second display device using a second wireless communication protocol that is different than the first wireless communication protocol.

8. The method of claim 7 , further comprising:
selecting, using a graphical user interface presented via a display of the first display device in connection with an analyte sensor application, the second display device for connection with the first display device.

9. The method of claim 8 , wherein:
the analyte sensor application processes the encrypted analyte data received by the first display device and presents such data via the display, and
a user interacts with the analyte sensor application via the graphical user interface, and the graphical user interface includes a button that is used to manage alert settings.

10. The method of claim 1 , wherein the messaging is different from the encrypted analyte data.

11. The method of claim 1 , wherein the first display device alarms the host based on the encrypted analyte data.

12. The method of claim 1 , wherein:
the first display device is configured to receive different streams of sensor information at respective different time intervals, and
at least one of the different streams corresponds to the encrypted analyte data.

13. An analyte sensor system comprising:
a transcutaneous analyte sensor configured to generate analyte measurements indicative of analyte concentrations in a host;
a sensor electronics module integral with, or releasably attachable to, the transcutaneous analyte sensor, the sensor electronics module operable to:
process the analyte measurements to generate analyte data;
authenticate a first display device for a first wireless connection by exchanging information related to authentication between the analyte sensor system and the first display device;
upon authenticating the first display device, periodically exchange messaging with the first display device to maintain the first wireless connection;
encrypt the analyte data to generate encrypted analyte data, wherein the analyte data includes glucose data; and
transmit the encrypted analyte data to the first display device during a time the first wireless connection is maintained, wherein the first display device displays at least some of the information associated with the analyte data and alarms the host using an alarm mechanism located on the first display device.

14. The analyte sensor system of claim 13 , the first display device is configured to process the encrypted analyte data and display the analyte data.

15. The analyte sensor system of claim 13 , wherein:
the analyte sensor system is in a storage mode before it is inserted into the host,
