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.

Claims

1. A method for wireless data communication between an analyte sensor system and a plurality of display devices capable of displaying analyte values wirelessly received from the analyte sensor system, the method comprising:

initiating a communication session to establish data communication channels among a first communication device coupled to a continuous analyte sensor configured to generate sensor data and one or more display devices of various types configured to display analyte values;

receiving, by the first communication device, a first data connection request from a first display device of a first type, wherein the request includes at least identification information of the first display device;

responsive to the request, consulting, by the first communication device, a first database, wherein the consultation includes identifying the first display device and corresponding authorization information of the first display device;

based on the consultation, determining that the first display device is authorized for the first data connection;

establishing a first data communication channel between the first communication device and the first display device during a first time period within the communication session;

receiving, by the first communication device, a second data connection request from a second display device, wherein the second display device is of a second type that is different than the first type, wherein the request includes at least identification information of the second display device;

responsive to the request, consulting, by the first communication device, the first database, wherein the consultation includes identifying the second display device and corresponding authorization information of the second display device;

based on the consultation, determining that the second display device is authorized for the second data connection;

establishing a second data communication channel between the first communication device and the second display device during a second time period within the communication session;

receiving by the first communication device a first and a second request from the first and the second display device respectively for the generated sensor data; and

maintaining connections of the first and the second data communication channels to provide the requested sensor data to the first and the second display device at the same time.

2. The method of claim 1, wherein the first database includes information related to authorization of at least the first and the second display devices.

3. The method of claim 1, further including determining that the first display device has paired previously with the first communication device prior to the establishment of the first data communication channel.

4. The method of claim 1, further including storing information related to the first display device and the second display device in a second database when the first data communication and the second data communication channels are established respectively.

5. The method of claim 1, further including determining that the second display device has paired previously with the first communication device prior to the establishment of the second data communication channel.

6. The method of claim 1, further including transmitting by the first communication device, a first series of advertisement signals prior to at least the establishment of the first and second data communication channels, and further transmitting at least a second series of advertisement signals after at least the establishment of the first and second data communication channels.

7. The method of claim 1, wherein the first type of display device is selected from a group consisting of a mobile phone, a smart watch, and a PDA.
