CONTINUOUS GLUCOSE MONITOR COMMUNICATION WITH MULTIPLE DISPLAY DEVICES

摘要

A continuous glucose monitor for wirelessly transmitting data relating to glucose value to a plurality of displays is disclosed, as well as systems and methods for limiting the number of display devices that can connect to a continuous glucose transmitter. In addition, security, including hashing techniques and a changing application key, can be used to provide secure communications between the continuous glucose transmitter and the displays. Also provided is a continuous glucose monitor and techniques for authenticating multiple displays, providing secure data transmissions to multiple displays, and coordinating the interaction of commands and data updates between multiple displays.

主权项

1. A method for connecting a transmitter of a continuous glucose system with a plurality of displays, comprising:
advertising, by the transmitter, at a defined communication interval; receiving, in response to the advertising, requests from a first display and a second display to connect with the transmitter; determining whether to authorize connections with the first display and the second display based a device type for the first display and a device type for the second display; executing an authentication process to pair the first display and the second display with the transmitter when the connections are authorized; and storing bonding information associated with the authentication process in memory.
