INFORMATION AND COMMUNICATION TECHNOLOGIES AIMING AT THE REDUCTION OF THEIR OWN ENERGY USE ## Abstract Systems, devices and methods are provided for power-efficient wireless communications between electronic devices. In particular, the embodiments disclosed herein can reduce battery consumption in a transmitting electronic device and enhance data integrity of data received by a receiving electronic device. According to the embodiments, a first electronic device transmits advertising packets according to a wireless communications protocol, wherein the advertising packets include a first payload data. In response to receiving the advertising packets, a second electronic device can transmit a scan request to the first electronic device which, in turn, terminates the transmission of advertising packets. ## Claims ### Claim 1 A method for monitoring an analyte level in a subject, the method comprising: sensing, by an analyte sensor, the analyte level in a bodily fluid of the subject; transmitting, by a sensor control device comprising sensor electronics communicatively coupled to the analyte sensor, a first plurality of advertising packets according to a wireless communications protocol, wherein the advertising packets include data indicative of the sensed analyte level; and terminating the transmission of the first plurality of advertising packets in response to receiving a scan request from a reader. ### Claim 2 (depends on 1) The method of claim 1, wherein the wireless communications protocol comprises a Bluetooth or a Bluetooth Low Energy protocol. ### Claim 3 (depends on 1) The method of claim 1, further comprising, transmitting, by the reader, the scan request to the sensor control device in response to receiving the first plurality of advertising packets. ### Claim 4 (depends on 1) The method of claim 1, further comprising, in response to receiving the scan request from the reader, identifying, by the sensor control device, a second plurality of advertising packets not received by the reader and transmitting a scan response comprising data indicative of the sensed analyte level from the second plurality of advertising packets. ### Claim 5 (depends on 4) The method of claim 4, wherein at least a portion of the data indicative of the sensed analyte level from the second plurality of advertising packets is different from the data indicative of the sensed analyte level from the first plurality of advertising packets. ### Claim 6 (depends on 1) The method of claim 1, wherein each of the first plurality of advertising packets is associated with a different Universal Unique Identifier (UUID). ### Claim 7 (depends on 6) The method of claim 6, further comprising registering, by the reader, each of the UUID's with an application program interface (API) of the reader. ### Claim 8 (depends on 1) The method of claim 1, wherein transmitting the first plurality of advertising packets according to a wireless communications protocol comprises repeatedly transmitting the first plurality of advertising packets. ### Claim 9 (depends on 8) The method of claim 8, wherein transmitting the first plurality of advertising packets according to a wireless communications protocol further comprises transmitting the first plurality of advertising packets in a non-sequential order. ### Claim 10 (depends on 8) The method of claim 8, wherein transmitting the first plurality of advertising packets according to a wireless communications protocol further comprises transmitting the first plurality of advertising packets in a randomized order. ### Claim 11 (depends on 10) The method of claim 10, wherein each of the first plurality of advertising packets includes packet order information. ### Claim 12 (depends on 11) The method of claim 11, further comprising reassembling, by the reader, the data indicative of the sensed analyte level based on the packet order information. ### Claim 13 (depends on 1) The method of claim 1, wherein the first plurality of advertising packets comprises at least one set of duplicate advertising packets. ### Claim 14 (depends on 13) The method of claim 13, wherein each set of duplicate advertising packets comprises two or more advertising packets including the same data indicative of the sensed analyte level. ### Claim 15 (depends on 13) The method of claim 13, wherein each of the first plurality of advertising packets is associated with a different Universal Unique Identifier (UUID). ### Claim 16 (depends on 1) The method of claim 1, wherein the reader is a smart phone. ### Claim 17 (depends on 1) The method of claim 1, wherein the data indicative of the sensed analyte level comprises a glucose level. ### Claim 18 (depends on 1) The method of claim 1, wherein the data indicative of the sensed analyte level comprises a rate of change of a glucose level. ### Claim 19 An analyte monitoring system, comprising: a sensor control device comprising one or more processors, a memory coupled to the one or more processors, wireless communications circuitry coupled to the one or more processors, and an analyte sensor configured to sense an analyte level in a bodily fluid of a subject, wherein the memory stores instructions that, when executed by the one or more processors, cause the one or more processors to cause a transmission of a first plurality of advertising packets according to a wireless communications protocol, wherein the advertising packets include data indicative of the sensed analyte level, and terminate the transmission of the first plurality of advertising packets in response to receiving a scan request from a reader. ### Claim 20 (depends on 19) The analyte monitoring system of claim 19, further comprising: a reader comprising one or more processors of the reader, a memory of the reader coupled to the one or more processors of the reader, and wireless communications circuitry of the reader, wherein the memory of the reader stores instructions that, when executed by the one or more processors of the reader, cause the one or more processors of the reader to cause a transmission of the scan request to the sensor control device in response to receiving the first plurality of advertising packets. ### Claim at position 21 21-52.
