A method for transmitting data between a first communication device associated with an analyte sensor and one or more second communication devices configured to provide user access to analyte values and/or information derived from analyte values, comprising: establishing a first communication channel with a primary device of the one or more second communication devices during a first time period within a communication window; and establishing a second communication channel with one or more secondary devices of the one or more second communication devices during a second time period within the communication window, the second time period different from the first time period, wherein establishing the first communication channel comprises transmitting, by the first communication device, beacons as a first invitation for a second communication device of said one or more second communication devices to establish a communication channel, and wherein the method further comprises: after transmitting the beacons as the first invitation, receiving by the first communication device a request from the primary device and authenticating the primary device; and after the request has been received and the primary device has been authenticated, transmitting analyte sensor data by the first communication device to the primary device; wherein establishing the second communication channel comprises resuming, by the first communication device, sending beacons as a second invitation for a second communication device of said one or more second communication devices to establish a communication channel, and wherein the method further comprises: after resuming sending the beacons as the second invitation, receiving by the first communication device a request from a secondary device of said one or more secondary devices and authenticating the secondary device; and after the request has been received and the secondary device has been authenticated, transmitting analyte sensor data by the first communication device to the secondary device, wherein the first time period within the communication window is reserved for communication with the primary device, and wherein, in the first time period, the first communication device only responds to and authenticates with the primary device and ignores requests from other second communication devices. establishing a first communication channel with a primary device of the one or more second communication devices during a first time period within a communication window; and establishing a second communication channel with one or more secondary devices of the one or more second communication devices during a second time period within the communication window, the second time period different from the first time period, wherein establishing the first communication channel comprises transmitting, by the first communication device, beacons as a first invitation for a second communication device of said one or more second communication devices to establish a communication channel, and wherein the method further comprises: after transmitting the beacons as the first invitation, receiving by the first communication device a request from the primary device and authenticating the primary device; and after the request has been received and the primary device has been authenticated, transmitting analyte sensor data by the first communication device to the primary device; after transmitting the beacons as the first invitation, receiving by the first communication device a request from the primary device and authenticating the primary device; and after the request has been received and the primary device has been authenticated, transmitting analyte sensor data by the first communication device to the primary device; wherein establishing the second communication channel comprises resuming, by the first communication device, sending beacons as a second invitation for a second communication device of said one or more second communication devices to establish a communication channel, and wherein the method further comprises: after resuming sending the beacons as the second invitation, receiving by the first communication device a request from a secondary device of said one or more secondary devices and authenticating the secondary device; and after the request has been received and the secondary device has been authenticated, transmitting analyte sensor data by the first communication device to the secondary device, wherein the first time period within the communication window is reserved for communication with the primary device, and wherein, in the first time period, the first communication device only responds to and authenticates with the primary device and ignores requests from other second communication devices. after resuming sending the beacons as the second invitation, receiving by the first communication device a request from a secondary device of said one or more secondary devices and authenticating the secondary device; and after the request has been received and the secondary device has been authenticated, transmitting analyte sensor data by the first communication device to the secondary device, wherein the first time period within the communication window is reserved for communication with the primary device, and wherein, in the first time period, the first communication device only responds to and authenticates with the primary device and ignores requests from other second communication devices.
