1. An analyte monitoring system, comprising:

  • an analyte sensor for positioning in fluid contact with interstitial fluid under a skin layer;

    sensor electronics operatively coupled to the analyte sensor and in signal communication with the analyte sensor, the sensor electronics including a memory device for storing data associated with the operation of the sensor electronics and monitored analyte level based on signals from the analyte sensor; and

    a data control unit in wireless communication with the sensor electronics, the data control unit configured to establish a communication range with the sensor electronics when positioned within a predetermined distance from the sensor electronics, the data control unit further configured to communicate one or more predefined commands to the sensor electronics when the communication range is established, and wherein the sensor electronics is configured to perform one or more predefined functions in response to the received one or more predefined commands and to transmit a response data packet to the data control unit based, at least in part, on the received one or more predefined commands;

    wherein, in response to receiving the one or more predefined commands, the sensor electronics is configured to retrieve identification information and to communicate the identification information to the data control unit, and the sensor electronics is configured to communicate data corresponding to the signals from the analyte sensor indicative of the monitored analyte level; and

    furtherwherein with each communication of data from the sensor electronics to the data control unit, the sensor electronics updates a memory location in the memory device of the sensor electronics.
