Abstract

Embodiments described herein include an analyte monitoring device. The analyte monitoring device generates sensor data indicative of an analyte level measured by an analyte sensor transcutaneously positioned in contact with a bodily fluid of the subject. The analyte monitoring device initializes a communication module using an advertisement scanning related instruction set, wherein the advertisement scanning related instruction set is a subset of a communications protocol startup instruction set including the advertisement scanning related instruction set and a non-advertisement scanning related instruction set. The analyte monitoring device issues one or more advertising packets and receives a connection request from a receiving device. The analyte monitoring device completes initialization of the communication module using the non-advertisement scanning related instruction set. The analyte monitoring device selects a subset of the sensor data, prepares a data packet comprising the subset of the sensor data, and transmits the data packet to the receiving device.

First claim

What is claimed is:

1. An analyte monitoring device comprising:
one or more processors,
an analyte sensor,
a communication module, and
one or more memories communicatively coupled to the one or more processors, the analyte sensor, and the communication module, and comprising instructions executable by the one or more processors to configure the one or more processors to perform operations comprising:
generating sensor data indicative of an analyte level measured by the analyte sensor, wherein at least a portion of the analyte sensor is transcutaneously positioned in contact with a bodily fluid of a subject;
initializing the communication module using an advertisement scanning related instruction set, wherein the advertisement scanning related instruction set is a subset of a communications protocol startup instruction set including the advertisement scanning related instruction set and a non-advertisement scanning related instruction set;
causing the communication module to issue one or more advertising packets;
receiving a connection request from a receiving device;
completing initialization of the communication module using the non-advertisement scanning related instruction set;
selecting a subset of the sensor data;
preparing a data packet comprising the subset of the sensor data; and
causing the communication module to transmit the data packet to the receiving device.

2. The analyte monitoring device of claim 1 , wherein the communication module is initialized responsive to the detection of expiration of a wakeup timer.

3. The analyze monitoring device of claim 1 , wherein initializing the communication module comprises transitioning the communication module from a sleep state to an active state.

4. The analyte monitoring device of claim 3 , wherein, after causing the communication module to issue the one or more advertising packets, the one or more processors are further configured to perform operations further comprising:
determining that the connection request has not been received from the receiving device for a period of time;
transitioning the communication module from the awake state to the sleep state; and
initializing the communication module using an advertisement scanning related instruction set a second time, wherein the connection request is received from the receiving device after the communication module has been initialized the second time.

5. The analyte monitoring device of claim 4 , wherein the communication module is transitioned from the awake state to the sleep state without executing the non-advertisement scanning related instruction set.

6. The analyte monitoring device of claim 1 , wherein the non-advertisement scanning related instruction set includes instructions related to initialization of a random access memory segment or block, initialization of sensing hardware; or initialization of an operating system service.

7. The analyte monitoring device of claim 1 , wherein the advertisement scanning related instruction set includes instructions related to detecting expiration of a wake-up timer, processor startup, initialization of a transmit circuit, formation of advertising data packets, transmission of advertising data packets, scanning one or more channels for a connection request from the receiving device, or validating or denying an incoming connection request.

8. The analyte monitoring device of claim 1 , wherein the connection request comprises criteria for selecting the subset of the sensor data.

9. The analyte monitoring device of claim 1 , wherein the one or more processors are further configured to perform operations further comprising selecting the subset of the sensor data based on a priority level associated with the sensor data.

10. The analyte monitoring device of claim 1 , wherein the receiving device is a fitness monitor or fitness device.

11. The analyte monitoring device of claim 1 , wherein the receiving device comprises medical components for use by the subject based on the subset of the sensor data.

12. The analyte monitoring device of claim 1 , wherein the receiving device is a smartphone or a smartwatch.

13. The analyte monitoring device of claim 1 , wherein the one or more processors are further configured to perform operations further comprising establishing a communication session with the receiving device by:
causing the communication module to transmit an acknowledgement of the connection request to the receiving device; and
performing a mutual authentication with the receiving device to generate a shared encryption key for subsequent communication sessions.

14. The analyte monitoring device of claim 13 , wherein the subset of the sensor data is encrypted in the data packet using the shared encryption key.

15. The analyte monitoring device of claim 1 , wherein the analyte comprises glucose, ketones, lactate, oxygen, hemoglobin A1C, albumin, alcohol, alkaline phosphatase, alanine transaminase, aspartate aminotransferase, bilirubin, blood urea nitrogen, calcium, carbon dioxide, chloride, creatinine, hematocrit, lactate, magnesium, oxygen, pH, phosphorus, potassium, sodium, total protein, or uric acid.

16. One or more computer-readable non-transitory storage media comprising instructions executable by one or more processors of an analyte monitoring device to cause the analyte monitoring device to perform operations comprising:
generating sensor data indicative of an analyte level measured by an analyte sensor of the analyte monitoring device, wherein at least a portion of the analyte sensor is transcutaneously positioned in contact with a bodily fluid of the subject;
initializing a communication module of the analyte monitoring device using an advertisement scanning related instruction set, wherein the advertisement scanning related instruction set is a subset of a communications protocol startup instruction set including the advertisement scanning related instruction set and a non-advertisement scanning related instruction set;
causing the communication module to issue one or more advertising packets;
receiving a connection request from a receiving device;
completing initialization of the communication module using the non-advertisement scanning related instruction set;
selecting a subset of the sensor data;
preparing a data packet comprising the subset of the sensor data; and
causing the communication module to transmit the data packet to the receiving device.

17. The one or more computer-readable non-transitory storage media of claim 16 , wherein the communication module is initialized responsive to the detection of expiration of a wakeup timer.

18. The one or more computer-readable non-transitory storage media of claim 16 , wherein initializing the communication module comprises transitioning the communication module from a sleep state to an active state.

19. The one or more computer-readable non-transitory storage media of claim 18 , wherein, after causing the communication module to issue the one or more advertising packets, the instructions are further executable by the one or more processors of the analyte monitoring device to perform further operations comprising:
determining that the connection request has not been received from the receiving device for a period of time;
transitioning the communication module from the awake state to the sleep state; and
initializing the communication module using an advertisement scanning related instruction set a second time, wherein the connection request is received from the receiving device after the commu
