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.

What is claimed is: 
     
         1 . A method for transmitting data between devices of an analyte monitoring system, the method comprising:
 generating sensor data using a sensor electronics module electrically connected to a continuous analyte sensor;   establishing a two-way communication channel between the sensor electronics module and the a display device and each of the sensor electronics module and display device transmitting at a first transmission power; and   initiating a low power transmission mode responsive to sensing user input at user interface of the display device indicative of entering the mode, wherein the low power transmission mode comprises one or both of the sensor electronics module and the display device transmitting at a second transmission power that is lower than the first 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 low power mode. 
     
     
         3 . The method of  claim 1 , wherein the display device prompts a user to input a duration of time for the low power transmission mode, and wherein the display device and the sensor electronics module automatically exit the low power transmission mode after expiration of the duration of time. 
     
     
         4 . The method of  claim 1 , further comprising initiating the low power transmission mode responsive to receiving user input indicative of starting the low power transmission mode, and exiting the low power transmission mode responsive to receiving user input indicative of ending the low power transmission mode. 
     
     
         5 . The method of  claim 5 , wherein the user input comprises sensing user selection of a user-selectable button on the user interface of the display device. 
     
     
         6 . The method of  claim 1 , wherein the second transmission power is in a range of about 25%-75% lower than the first transmission power. 
     
     
         7 . 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 analyte sensor and generate analyte sensor data using the continuous analyte sensor; and   a display device configured to wirelessly receive information indicative of the analyte sensor data from the sensor electronics module,   wherein the sensor electronics module and display device are configured to establish a two-way communication channel between the sensor electronics module and the a display device,   wherein each of the sensor electronics module and display device transmit at a first transmission power during a normal operating mode, and   wherein each of the sensor electronics module and display device transmit at a second, lower transmission power during a low power transmission mode initiating a low power transmission mode, the low transmission power mode initiated responsive to receiving user input at user interface of the display device indicative of entering the mode.   
     
     
         8 . The system of  claim 6 , wherein the initiating comprises the display device sending a command to the sensor electronics module to enter the low power mode. 
     
     
         9 . The system of  claim 6 , wherein the display device is configured to prompt a user to input a duration of time for the low power transmission mode, and wherein the display device and the sensor electronics module automatically exit the low power transmission mode after expiration of the duration of time. 
     
     
         10 . The system of  claim 6 , wherein initiating the low power transmission mode is responsive to receiving user input indicative of starting the low power transmission mode, and exiting the low power transmission mode responsive to receiving user input indicative of ending the low power transmission mode. 
     
     
         11 . The system of  claim 10 , wherein the user input comprises sensing user selection of a user-selectable button on the user interface of the display device. 
     
     
         12 . The system of  claim 6 , wherein the transmission power during the low power transmission mode is in a range of about 25%-75% lower than the transmission power during the normal operating mode.
