Claims

1. A method, comprising:
generating, using a sensor control unit coupled to an analyte sensor in fluid contact with body fluid, a data packet including a current sensor data point, one or more prior sensor data points, and calibration data;
communicating the data packet including the current sensor data point, the one or more prior sensor data points, and the calibration data to a receiver; and
incrementing, at the sensor control unit, a predetermined value when the data packet is communicated to the receiver.
2. The method of claim 1, wherein the data packet is communicated via wireless communication.
3. The method of claim 2, wherein the wireless communication is radio frequency (RF) communication.
4. The method of claim 1, wherein the calibration data comprises 8 bytes of data.
5. The method of claim 1, wherein the current sensor data point and the one or more prior sensor data points are obtained using the analyte sensor.
6. The method of claim 5, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.
7. The method of claim 5, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.
8. The method of claim 6, wherein the working electrode comprises a mediator crosslinked with the polymer disposed on the working electrode.
9. The method of claim 1, wherein the calibration data is used to calibrate the analyte sensor.
10. The method of claim 1, wherein the data packet further includes temperature data associated with the analyte sensor.
11. An apparatus, comprising:
an analyte sensor in fluid contact with bodily fluid;
a communication unit coupled to the analyte sensor and configured to communicate a data packet including a current sensor data point, one or more prior sensor data points, and calibration data to a receiver;
a memory operatively coupled to the communication unit and configured to store the current sensor data point, the one or more prior sensor data points, and the calibration data; and
an incrementer configured to increment a predetermined value when the data packet is communicated to the receiver.
12. The apparatus of claim 11, wherein the communication unit is a wireless communication unit.
13. The apparatus of claim 12, wherein the wireless communication unit is a radio frequency (RF) communication unit.
14. The apparatus of claim 11, wherein the calibration data comprises 8 bytes of data.
15. The apparatus of claim 11, further comprising the analyte sensor operatively coupled to the communication unit and configured to obtain the current sensor data point and the one or more prior sensor data points.
16. The apparatus of claim 15, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising an analyte-responsive enzyme bonded to a polymer disposed on the working electrode.
17. The apparatus of claim 15, wherein the analyte sensor comprises a plurality of electrodes including a working electrode comprising a mediator bonded to a polymer disposed on the working electrode.
18. The apparatus of claim 16, wherein the working electrode comprises a mediator crosslinked with the polymer disposed on the working electrode.
19. The apparatus of claim 11, wherein the calibration data is used to calibrate the analyte sensor.
20. The apparatus of claim 11, wherein the data packet further includes temperature data associated with the analyte sensor.
