Abstract
Systems and methods for processing, transmitting and displaying data received from an analyte sensor, such as a glucose sensor, are provided. The data can be displayed on a hand-held display device having a display such as a key fob device including a user interface, such as an LCD and one or more buttons that allows a user to view data, and a physical connector, such as USB port.
Claims15
A method for transmitting data between a first communication device associated with an analyte sensor and a primary communication device and a secondary communication device configured to provide user access to analyte values and/or information derived from analyte values, comprising:
- establishing a communication channel between a secondary communication device and a first communication device during a transmission time window of a sensor session;
- determining whether a primary communication device has previously been in communication with the first communication device during the sensor session;
- and
- rejecting requests for data or commands sent by the secondary communication device to the first communication device if the primary communication device has not been in communication with the first device during the sensor session.
A method of transmitting data between a first communication device associated with an analyte sensor and a primary communication device and a secondary communication device, each of the primary communication device and the secondary communication device configured to provide user access to analyte values and/or information derived from analyte values, comprising:
- determining whether a first communication channel has been established between a first communication device and a primary communication device during a time window;
- and establishing a second communication channel between the first communication device and a secondary communication device during the time window only if the first communication channel was established during the time window.
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 analyte values and/or information derived from analyte values, comprising:
- switching a first communication device between a plurality of transmission window states, the plurality of window transmission modes including:
- a first transmission window state in which the first communication device does not open a transmission window,
- a second transmission window state in which the first communication device periodically opens a transmission window at a first frequency, and
- a third transmission window state in which the first communication device periodically opens a transmission window at a second frequency that is less than the first frequency;
- and
- transmitting one or more beacons during each transmission window state.
A method for transmitting data between a first communication device associated with an analyte sensor and second communication device configured to provide user access to analyte values and/or information derived from analyte values, the method comprising:
- storing technical support data in a log file in memory in a first communication device;
- determining that a second communication device should receive at least some of the stored technical support data;
- transmitting, using the first communication device, a message indicative of the determination;
- receiving a request from the second communication device for at least some of the stored technical support data responsive to the transmitted message;
- and
- transmitting the at least some of the stored technical support data.
