1. An analyte monitoring system, comprising:

  • a sensor configured to generate signals corresponding to a monitored analyte level in interstitial fluid; and

    sensor electronics operatively coupled to the sensor, the sensor electronics comprising (i) a processor configured to process the generated signals to form data packets associated with the generated signals from the sensor, and (ii) a temperature sensor configured to monitor temperature associated with the sensor, wherein the monitored temperature is used to adjust the processed generated signals;

    wherein the sensor electronics include programming to provide data communications to a receiving device by at least communicating one or more data packets with each data communication during a period of time corresponding to a predetermined listening window, the data packets including at least a current data point that corresponds to an analyte level of a current time period, a time value information that corresponds to a point in time when the one or more data packets are communicated from the sensor electronics to the receiving device, and data identifying the sensor electronics;

    wherein the receiving device is configured to use the time value information and the data identifying the sensor electronics to identify the predetermined listening window;

    wherein the sensor electronics further include programming to communicate the one or more data packets by data communications to the receiving device at a time outside the predetermined listening window in response to a user request provided from the receiving device; and

    wherein the sensor electronics further include programming to, in response to the current data point not being successfully received by the receiving device, transmit at least one subsequent data communication including a subsequent data packet during a subsequent widened time period greater than the predetermined listening window, the subsequent data packet including at least a subsequent data point that corresponds to an analyte level at that subsequent time period.
