Abstract

Systems and methods for processing, transmitting and displaying data received from an analyte sensor, such as a glucose sensor, are disclosed. In an embodiment, a method for transmitting data between a first communication device associated with an analyte sensor and a second communication device configured to provide user access to sensor-related information comprises: activating a transceiver of a first communication device associated with an analyte sensor at a first time; and establishing a two-way communication channel with the second communication device; wherein the activating comprises waking the transceiver from a low power sleep mode using a forced wakeup from the second communication device.

Claims

1. A method for transmitting data between devices of an analyte monitoring system, the method comprising:

generating sensor analyte data using a sensor electronics module electrically connected to a continuous analyte sensor;

establishing a first communication mode between the sensor electronics module and a display device, wherein the first communication mode is associated with a first transmission power;

transmitting the sensor analyte data to the display device via the first communication mode, wherein the transmitting comprises periodically opening and closing a transmission window between the sensor electronics module and the display device;

initiating a second communication mode between the sensor electronics module and the display device responsive to sensing user input at a user interface of the display device indicative of entering the second communication mode; and

upon the initiation of the second communication mode, causing a forced transmission of the sensor analyte data from the sensor electronics module to the display device via the second communication mode during the closing of the transmission window that is associated with the first communication mode, wherein the second communication mode is associated with a second transmission power.

2. The method of claim 1, wherein the initiating comprises the display device sending a command to the sensor electronics module to enter the second communication mode.

3. The method of claim 1, further comprising exiting the second communication mode responsive to receiving user input at the user interface of the display device indicative of ending the second communication mode.

4. The method of claim 3, wherein the user input comprises sensing user selection of a user-selectable button on the user interface of the display device.

5. The method of claim 1, wherein the second transmission power is different from the first transmission power.

6. The method of claim 1, wherein the user input comprises sensing user selection of a user-selectable button on the user interface of the display device.

7. The method of claim 1, further comprising activating a transceiver that is related to the second communication mode upon the initiation of the second communication mode.

8. The method of claim 1, further comprising transmitting, via the second communication mode, a calibration value from the display device to the sensor electronics module, and receiving an updated glucose value at the display device in response to said transmitting via the second communication mode the calibration value.

9. The method of claim 1, wherein the forced transmission via the second communication mode is out of sync with the periodic opening and closing of the transmission window.

10. A system for monitoring analyte concentration data of a host, comprising:

a continuous analyte sensor;

a sensor electronics module configured to electrically couple to the continuous analyte sensor and generate sensor analyte data using the continuous analyte sensor; and

a display device configured to wirelessly receive information indicative of the sensor analyte data from the sensor electronics module,

wherein the sensor electronics module and the display device are configured to establish a first communication mode associated with a first transmission power between the sensor electronics module and the display device;

wherein the sensor electronics module is further configured to transmit the sensor analyte data to the display device via the first communication mode;

wherein the transmission comprises periodical opening and closing of a transmission window between the sensor electronics module and the display device, and

wherein the sensor electronics module and the display device are further configured to initiate a second communication mode associated with a second transmission power, the initiation responsive to receiving user input at via a user interface of the display device indicative of entering the second communication mode, wherein the initiation causes a forced transmission of the sensor analyte data from the sensor electronics module to the display device via the second communication mode during the closing of the transmission window that is associated with the first communication mode.

11. The system of claim 10, wherein the display device is further configured to send a command to the sensor electronics module to enter the second communication mode.

12. The system of claim 10, wherein the system exits the second communication mode responsive to receipt of the user input via the user interface of the display device, wherein the user input indicates ending the second communication mode.

13. The system of claim 12, wherein the user input comprises sensing user selection of a user-selectable button on the user interface of the display device.

14. The system of claim 10, wherein the second transmission power is different from the first transmission power.
