  • Publication number: 20200037939
    Abstract: Systems and methods for wireless communication of analyte information are disclosed. Example embodiments include an analyte sensor system. The analyte sensor system may include an analyte sensor to gather information related to a level of an analyte in a host. The analyte sensor system may include circuitry to transmit and receive wireless signals using a first antenna. The analyte sensor may be coupled to the circuitry before the analyte sensor system is transitioned into an operational state. The analyte sensor system may include a second antenna to receive an input signal from a source external to the analyte sensor system and to transmit a modified signal. The circuitry may use the first antenna to receive the modified signal. The analyte sensor system may transition into the operational state in response to the modified signal received using the first antenna.
