1. An analyte monitoring system, comprising:

  • a sensor configured to perform measurements indicative of analyte levels;

    a sensor electronics unit communicatively coupled to the sensor and comprising;

    a memory;

    a controller configured to receive the measurements indicative of analyte levels and process the received measurements; and

    at least one communicator configured to use a first communication protocol to wirelessly transmit sensor information associated with analyte levels; and

    at least one display device paired or pairable with the sensor electronics unit for wireless communication with the sensor electronics unit using the first communication protocol, the at least one display device comprising;

    a memory;

    a controller;

    at least one communicator configured to use the first communication protocol to wirelessly receive the sensor information associated with analyte levels sent by the sensor electronics unit, andat least one wireless communicator configured to use a second communication protocol to retrieve data indicative of analyte levels on-demand from the sensor electronics unit;

    wherein the at least one sensor electronics unit communicator that is configured to use the first communication protocol and the at least one display device communicator that is configured to use the first communication protocol are configured to perform an authentication procedure to enable wireless transmission of the sensor information from the sensor electronics unit to the at least one display device using the first communication protocol;

    wherein the memory of the sensor electronics unit has stored therein a white list indicating permission level of one or more display devices for communication with the sensor electronics unit after the authentication procedure has been performed; and

    wherein the controller of the sensor electronics unit is configured to directly access the white list stored in the sensor electronics unit memory to allow the sensor electronics unit communicator to communicate using the first communication protocol with display devices on the white list and to not allow communication using the first communication protocol with display devices that are not on the white list.
