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 wirelessly communicating glucose data, the method comprising:
generating glucose sensor data associated with a glucose concentration in a host using a transcutaneous glucose sensor;
processing the generated glucose sensor data using a sensor electronics unit coupled to the transcutaneous glucose sensor to generate processed glucose sensor data;
operating in a first wireless communication mode between the sensor electronics unit and a display device configured to display information related to the glucose sensor data generated by the transcutaneous glucose sensor, operating in the first wireless communication mode comprising:
the sensor electronics unit transmitting to the display device a first data packet at a first time and a second data packet at a second time, wherein the first data packet and the second data packet both contain encrypted information associated with the glucose sensor data, and wherein the first time and the second time define a time interval;
the sensor electronics unit transmitting one or more messages to the display device during the time interval such that the sensor electronics unit and the display device remain continuously connected over the duration of the time interval; and

operating in a second wireless communication mode between the sensor electronics unit and the display device generated by the transcutaneous glucose sensor, operating in the second wireless communication mode comprising:
periodically establishing and disconnecting a wireless connection between the sensor electronics unit and the display device at pre-determined time intervals; and
while the connection is established, transmitting encrypted information associated with the glucose sensor data to the display device.

2. The method of claim 1 , comprising switching from operating in the first wireless communication mode to operating in the second wireless communication mode or switching from operating in the second wireless communication mode to operating in the first wireless communication mode.

3. The method of claim 2 , wherein the switching is based on user input.

4. The method of claim 2 , wherein the switching is based on one or more switching criteria.

5. The method of claim 2 , further comprising receiving an indication related to battery management; wherein the switching is done based on the indication.

6. The method of claim 4 , wherein the switching criteria comprise:
a type of display device;
user information;
the availability of display devices for connection;
a priority scheme regarding display devices;
quality of service;
battery life;
time of day; and
a location.

7. The method of claim 2 , further comprising, presenting a notification to the user related to the switching.

8. The method of claim 1 , wherein, while the sensor electronics unit and the display device remain continuously connected, the sensor electronics unit transmitting the analyte data to the display device is done upon encrypted information associated with the glucose sensor data becoming available for transmission.

9. A method for wirelessly communicating glucose data, the method comprising:
generating glucose sensor data associated with a glucose concentration in a host using a transcutaneous glucose sensor;
processing the generated glucose sensor data using a sensor electronics unit coupled to the transcutaneous glucose sensor to generate processed glucose sensor data;
authenticating a display device configured to display information related to the glucose sensor data, for a first wireless connection, by exchanging information related to authentication between the sensor electronics unit and the display device; and
upon authenticating the display device:
operating the sensor electronics unit in a first wireless communication mode, operating in the first wireless communication mode comprising:
the sensor electronics unit periodically exchanging messages with the display device over the first wireless connection for a time period; and
the sensor electronics unit transmitting data packets containing encrypted information associated with the glucose sensor data generated by the transcutaneous glucose sensor to the display device during the time period over the first wireless connection, wherein the messages and the data packets are interspersed with each other to maintain the first wireless connection continuously connected between the sensor electronics unit and the display device; and

operating the sensor electronics unit in a second wireless communication mode, operating in the second wireless communication mode comprising:
the sensor electronics unit periodically establishing and disconnecting the first wireless connection between the sensor electronics unit and the display device at pre-determined time intervals; and
while the first wireless connection is established, the sensor electronics unit transmitting first encrypted information associated with the glucose sensor data generated by the transcutaneous glucose sensor to the display device.

10. The method of claim 9 , further comprising terminating the first wireless connection.

11. The method of claim 10 , further comprising:
establishing a second wireless connection between sensor electronics unit and the display device;
the sensor electronics unit periodically exchanging messages with the display device to maintain continuous communication over the second wireless connection; and
the sensor electronics unit transmitting second encrypted information associated with the glucose sensor data to the display device over the second wireless connection that is continuously connected between the sensor electronics unit and the display device;
wherein, for the second wireless connection, the periodically exchanging the messages and the transmitting the second encrypted information are based on authenticating the display device for the first wireless connection.

12. The method of claim 9 , comprising switching from operating in the first wireless communication mode to operating in the second wireless communication mode or switching from operating in the second wireless communication mode to operating in the first wireless communication mode.
