System and method for communication of analyte data

An analyte sensor system comprising:

• a transcutaneous analyte sensor configured to generate analyte measurements indicative of analyte concentrations in a host;
• a sensor electronics module integral with, or releasably attachable to, the transcutaneous analyte sensor, the sensor electronics module operable to:
• process the analyte measurements to generate analyte data;
• authenticate a first display device for a first wireless connection by exchanging information related to authentication between the analyte sensor system and the first display device;
• upon authenticating the first display device, periodically exchange messaging with the first display device to maintain the first wireless connection;
• encrypt the analyte data to generate encrypted analyte data, wherein the analyte data includes glucose data;
• and
• transmit the encrypted analyte data to the first display device during a time the first wireless connection is maintained, wherein the first display device displays at least some of the information associated with the analyte data and alarms the host using an alarm mechanism located on the first display device.

A non-transitory computer readable medium having instructions stored thereon that, when executed by an analyte sensor system, cause the analyte sensor system to perform a method for wireless communication of analyte data, the method comprising:

• generating analyte measurements indicative of analyte concentrations in a host using a transcutaneous analyte sensor of the analyte sensor system;
• processing the analyte measurements using a sensor electronics module integral with, or releasably attachable to, the transcutaneous analyte sensor to generate analyte data;
• authenticating a first display device for a first wireless connection by exchanging information related to authentication between the analyte sensor system and the first display device;
• upon authenticating the first display device, the analyte sensor system periodically exchanging messaging with the first display device to maintain the first wireless connection;
• encrypting the analyte data to generate encrypted analyte data, wherein the analyte data includes glucose data;
• and
• the analyte sensor system transmitting the encrypted analyte data to the first display device during a time the first wireless connection is maintained, wherein the first display device displays at least some of the information associated with the analyte data and alarms the host using an alarm mechanism located on the first display device.
