Systems and methods for a continuous monitoring of analyte values

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.

What is claimed is: 
     
         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 a first series of advertisement signals generated by the analyte sensor system beginning at a first time;   receiving a data connection request from a mobile device at a second time;   establishing a data connection with the mobile device;   transmitting by the analyte sensor system a connection interval indicative of a difference between the second time and the first time to the mobile device;   transmitting by the analyte sensor system an analyte value to the mobile device;   terminating the data connection with the mobile device; and   causing a transceiver of the analyte sensor system to enter a sleep state.   
     
     
         2 . The method of  claim 1  further comprising:
 causing the transceiver to exit the sleep mode after a predetermined time; and 
 transmitting 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 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 for advertisement signals generated by the analyte sensor system;   receiving an advertisement signal from a transceiver of the analyte sensor system; transmitting a data connection request to the transceiver of the analyte sensor system;   establishing a data connection with the transceiver if the data connection request is granted;   receiving from the analyte sensor system a connection interval indicative of a difference between a first time at which the transceiver started to transmit a series of advertisement signals and a second time at which the transceiver received the data connection request from the mobile device;   receiving by the mobile device an analyte value from the transceiver of the analyte sensor system;   terminating the data connection with the transceiver, thereby causing the transceiver to enter a sleep mode;   entering an inactive mode during which the mobile device does not communicate with the transceiver;   calculating an exit time at which the mobile device is to exit the inactive mode based at least partly on the connection interval;   exiting the inactive mode at the exit time; and   searching 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 while the transceiver was in a previous sleep mode. 
     
     
         7 . The method of  claim 5 , wherein the exit time is given by:
 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 mobile device.
