1. An in vivo analyte monitoring system, comprising:

  • (a) a sensor control device comprising;

    an analyte sensor adapted to sense an analyte level in a human body; and

    wireless communication circuitry adapted to wirelessly transmit data indicative of the sensed analyte level according to a near field communication (NFC) protocol;

    (b) a relay device comprising;

    first wireless communication circuitry adapted to receive the data indicative of the sensed analyte level directly from the sensor control device according to the NFC protocol, wherein the first wireless communication circuitry is configured to transmit a request for analyte data to the sensor control device;

    second wireless communication circuitry adapted to wirelessly transmit the data indicative of the sensed analyte level according to a Bluetooth or Bluetooth Low Energy protocol;

    processing circuitry; and

    a memory on which one or more instructions are stored that, when executed by the processing circuitry, cause the processing circuitry to cause the first wireless communication circuitry to transmit the request for analyte data to the sensor control device during an idle time of the sensor control device; and

    (c) a handheld reader device comprising;

    wireless communication circuitry adapted to receive the data indicative of the sensed analyte level directly from the relay device according to the Bluetooth protocol;

    processing circuitry; and

    a memory on which one or more instructions are stored that, when executed by the processing circuitry, cause the processing circuitry to convert the data indicative of the sensed analyte level into a user readable form.
