1. A method for continuous measurement of a glucose level of a host using a glucose monitoring system, the method comprising:

  • periodically receiving glucose sensor data from a continuous glucose sensor that is configured to measure a glucose concentration of a host;

    calibrating, using electronics of the glucose monitoring system, the glucose sensor data from the continuous glucose sensor;

    storing, using the electronics of the glucose monitoring system, the calibrated glucose sensor data in computer memory;

    wirelessly receiving, using electronics of the glucose monitoring system, a first status request associated with a status of an event;

    in response to receiving the first status request, sending, using the electronics of the glucose monitoring system, a first status message that indicates the event is in the first status state;

    wirelessly sending, using the electronics of the glucose monitoring system, a first data package having some of the calibrated glucose sensor data stored in the computer memory;

    determining, using the electronics of the glucose monitoring system, the event changed to a second status state that is different from the first status state;

    wirelessly receiving, using the electronics of the glucose monitoring system, a second status request associated with the status of the event;

    wirelessly sending, using the electronics of the glucose monitoring system, a second status message indicating the event is in the second status state;

    wirelessly receiving, using the electronics of the glucose monitoring system, a second data package having data content limited to sensor data generated by a sensor that is different from the continuous glucose sensor; and

    changing, using the electronics of the glucose monitoring system, the status of the event to the first state responsive to receipt of the sensor data generated by the sensor that is different from the continuous glucose sensor included in the second data package.
