A method of transmitting data between an analyte sensor communication device associated with a continuous glucose sensor and a plurality of display devices (14, 16, 18, 20) configured to provide user access to glucose measurement values received from the continuous glucose sensor and/or information derived from the glucose measurement values, the method comprising, during a sensor session: (i) at a first predetermined time in an update interval T update of a plurality of update intervals, opening a transmission window to accept a request for establishing a communication channel and activating a transceiver of the analyte sensor communication device, wherein the transceiver remains activated during the transmission window; (ii) establishing a first authenticated two-way communication channel, by the transceiver of the analyte sensor communication device, only with a first display device of the plurality of display devices (14, 16, 18, 20) during a first time period within the transmission window, the first authenticated two-way communication channel being for transmission of glucose measurement values to the first display device, wherein in the first time period, the analyte communication device is configured to only respond to and authenticate with the first display device and ignore other requests to establish a communication channel; (iii) transmitting glucose measurement values from the analyte sensor communication device to the first display device using the first authenticated two-way communication channel during the first time period; (iv) closing the first authenticated two-way communication channel; (v) after closing the first authenticated two-way communication channel, establishing a second authenticated two-way communication channel, by the transceiver of the analyte sensor communication device, with a second display device of the plurality of display devices only during a second, different, time period within said transmission window, the second authenticated two-way communication channel being for transmission of glucose measurement values to the second display device; (vi) transmitting glucose measurement values from the analyte sensor communication device to the second display device using the second authenticated two-way communication channel during the second time period; (vii) closing the second authenticated two-way communication channel; (viii) after closing the second authenticated two-way communication channel, closing the transmission window and deactivating the transceiver of the analyte sensor communication device at a second time in the update interval until the first predetermined time in the next update interval T update of the plurality of update intervals; and repeating steps (i) - (viii) for the next update interval T update. (i) at a first predetermined time in an update interval T update of a plurality of update intervals, opening a transmission window to accept a request for establishing a communication channel and activating a transceiver of the analyte sensor communication device, wherein the transceiver remains activated during the transmission window; (ii) establishing a first authenticated two-way communication channel, by the transceiver of the analyte sensor communication device, only with a first display device of the plurality of display devices (14, 16, 18, 20) during a first time period within the transmission window, the first authenticated two-way communication channel being for transmission of glucose measurement values to the first display device, wherein in the first time period, the analyte communication device is configured to only respond to and authenticate with the first display device and ignore other requests to establish a communication channel; (iii) transmitting glucose measurement values from the analyte sensor communication device to the first display device using the first authenticated two-way communication channel during the first time period; (iv) closing the first authenticated two-way communication channel; (v) after closing the first authenticated two-way communication channel, establishing a second authenticated two-way communication channel, by the transceiver of the analyte sensor communication device, with a second display device of the plurality of display devices only during a second, different, time period within said transmission window, the second authenticated two-way communication channel being for transmission of glucose measurement values to the second display device; (vi) transmitting glucose measurement values from the analyte sensor communication device to the second display device using the second authenticated two-way communication channel during the second time period; (vii) closing the second authenticated two-way communication channel; (viii) after closing the second authenticated two-way communication channel, closing the transmission window and deactivating the transceiver of the analyte sensor communication device at a second time in the update interval until the first predetermined time in the next update interval T update of the plurality of update intervals; and
