INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## 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 ### Claim 1 An analyte sensor system configured for wireless data communication with a plurality of display devices, the analyte sensor system comprising: sensor electronics configured for operable connection to a transcutaneous analyte sensor, wherein the sensor electronics comprises: a transceiver configured to transmit and receive wireless signals; and a processor operatively connected to the transceiver, wherein the processor is configured to: store, access, and modify first information identifying one or more display devices as currently authorized to receive and display analyte values to a host; store, access, and modify second information identifying a display device as a currently active display device; receive a first data connection request from a first display device; determine that the first display device is identified as a currently authorized display device; establish a data connection with the first display device in response to the determination that the first display device is identified as a currently authorized display device; receive a request from the first display device to identify the first display device as the currently active display device; in response to the request, determine that a second display device is identified as the currently active display device; transmit the determination that a second display device is identified as the currently active display device to the first display device; receive a request to modify the second information to replace the second display device with the first display device as the currently active display device; modify the second information in accordance with the request; and terminate the first data connection with the first display device. ### Claim 2 The analyte sensor system of 1, wherein at least one of the first display device and the second display device is a custom analyte monitoring device and the other of the first display device and the second display device is a mobile device. ### Claim 3 (depends on 1) The analyte sensor system of claim 1, wherein the processor is configured to reject a data connection request from a display device not identified in the first information at a radio hardware level. ### Claim 4 (depends on 1) The analyte sensor system of claim 1, wherein the processor is further configured to: cause the transceiver to transmit a second series of advertisement signals, receive a second data connection request from the first display device, cause the transceiver to establish a second data connection with the first display device, determine that the first display device is identified in the second information, cause the transceiver to transmit an analyte value to the first display device, and cause the transceiver to terminate the second data connection with the first display device. ### Claim 5 (depends on 1) The analyte sensor system of claim 1, wherein the transcutaneous analyte sensor is a transcutaneous glucose sensor. ### Claim 6 The analyte sensor system of 9, wherein at least one of the first display device and the second display device is a custom analyte monitoring device and the other of the first display device and the second display device is a mobile device. ### Claim 7 (depends on 6) The analyte sensor system of claim 6, wherein the mobile device is a mobile phone. ### Claim 8 (depends on 5) The analyte sensor system of claim 5, wherein the processor is configured to reject a data connection request from a display device not identified in the first information at a radio hardware level. ### Claim 9 (depends on 8) The analyte sensor system of claim 8, wherein the processor comprises a link layer (LL) controller. ### Claim 10 (depends on 9) The analyte sensor system of claim 9, wherein the first information comprises a white list maintained in the LL controller. ### Claim 11 (depends on 5) The analyte sensor system of claim 5, wherein the processor is further configured to: cause the transceiver to transmit a second series of advertisement signals, receive a second data connection request from the first display device, cause the transceiver to establish a second data connection with the first display device, determine that the first display device is identified in the second information, cause the transceiver to transmit an analyte value to the first display device, and cause the transceiver to terminate the second data connection with the first display device. ### Claim 12 (depends on 11) The analyte sensor system of claim 11, wherein the processor is further configured to: cause the transceiver to enter a sleep mode, and cause the transceiver to exit the sleep mode after a predetermined time. ### Claim 13 (depends on 12) The analyte sensor system of claim 12, wherein the predetermined time is between about 200 and 300 seconds. ### Claim 14 (depends on 12) The analyte sensor system of claim 12, wherein the processor is further configured to take a measurement of an output of the analyte sensor while the transceiver is in the sleep mode. ### Claim 15 (depends on 12) The analyte sensor system of claim 12, wherein the processor is further configured to: cause the transceiver to transmit a third series of advertisement signals after exiting the sleep mode, receive a third data connection request from a second display device, cause the transceiver to establish a third data connection with the second display device if it is determined that the second display device is identified in the first list, cause the transceiver to transmit a third signal to the second display indicating that a different display device is identified in the second list, receive a fourth signal from the second display device, the fourth signal indicating that the third display device is not a newly selected active display device, and cause the transceiver to terminate the third data connection with the second display device without changing the second list.
