Abstract

Methods and apparatus, including computer program products, are provided for remote monitoring. In some example implementations, there is provided a method. The method may include receiving, at a remote monitor, a notification message representative of an event detected, by a server, from analyte sensor data obtained from a receiver monitoring an analyte state of a host; presenting, at the remote monitor, the notification message to activate the remote monitor, wherein the remote monitor is configured by the server to receive the notification message to augment the receiver monitoring of the analyte state of the host; accessing, by the remote monitor, the server, in response to the presenting of the notification message; and receiving, in response to the accessing, information including at least the analyte sensor data. Related systems, methods, and articles of manufacture are also disclosed.

Claims

1. A method for wireless communication between computing devices of a continuous glucose monitoring system, comprising:

receiving, using a gateway device, a heartbeat message from a receiver, the heartbeat message triggering connection logic;

requesting a latest analyte concentration value and a receiver time from the receiver;

identifying sensor data gaps of analyte concentration data stored at a remote server;

requesting, using the gateway, one or more timeframes of sensor data from the receiver based on the identified data gaps; and

providing the sensor data to the server.

2. The method of claim 1, further comprising:

requesting manufacturing data from the receiver, wherein the manufacturing data comprises a unique identifier associated with the receiver; and

checking a status of the receiver based on the manufacturing data, the checking comprising sending a message to the remote server and subsequently receiving an indication of whether the status of the receiver is valid or invalid from the remote server,

wherein the requesting of the latest analyte concentration value only occurs if the status of the receiver is valid.

3. The method of claim 1, further comprising:

requesting a universal time from the server; and

calculating a drift in time based on a difference between the receiver time and the universal time,

wherein the identifying the sensor data gaps is based on the drift in time.

4. The method of claim 3, further comprising storing the drift in a memory of the gateway device.

5. A continuous glucose monitoring system, comprising:

one or more processors; and

non-transitory computer instructions executable by the one or more processors, the instructions comprising;

receiving, using a gateway device, a heartbeat message from a receiver, the heartbeat message triggering connection logic,

requesting a latest analyte concentration value and a receiver time from the receiver,

identifying sensor data gaps of analyte concentration data stored at a server,

requesting, using the gateway, one or more timeframes of sensor data from the receiver based on the identified data gaps, and

providing the requested sensor data to the server.

6. The system of claim 5, wherein the instructions further comprise:

requesting manufacturing data from the receiver, wherein the manufacturing data comprises a unique identifier associated with the receiver; and

checking a status of the receiver based on the manufacturing data, the checking comprising sending a message to a remote server and receiving an indication of whether the status of the receiver is valid or invalid,

wherein the requesting of the latest analyte concentration value only occurs if the status of the receiver is valid.

7. The system of claim 5, wherein the instructions further comprise:

requesting a universal time from the server; and

calculating a drift in time based on a difference between the receiver time and the universal time,

wherein the identifying the sensor data gaps is based on the drift in time.

8. The system of claim 7, wherein the instructions further comprise storing the drift in memory of the gateway device.

9. A method for wireless communication between computing devices of a continuous glucose monitoring system, comprising:

notifying a remote server of a remote monitoring session starting; and

requesting and syncing past data with the server to ensure no gaps in data over a predetermined time period or predetermined amount of most recent glucose measurements, syncing including only uploading glucose concentration data determined to not already be stored at the server.

10. The method of claim 9, wherein the determining is based on a latest analyte concentration value provided by the server.

11. The method of claim 10, further comprising marking all analyte concentration data stored locally as uploaded to the server after the syncing is complete.

16. The method of claim 11, further comprising transmitting a CheckSession call to the server to keep a current login session active.

12. A method for wireless communication between computing devices of a continuous glucose monitoring system, comprising:

iteratively receiving a heartbeat message transmitted by a receiver;

determining if it is time to request data from the receiver responsive to each received heartbeat message based on whether more than a predetermined amount of time has elapsed based on a heartbeat counter; and

obtaining glucose concentration data from the receiver if it is determined that it is time to request sensor data from the receiver.

13. The method of claim 12, wherein obtaining further comprises requesting a latest glucose value data and a current system time from the receiver, and uploading the requested latest glucose value data to a remote server upon receipt of the requested latest glucose value data.

14. The method of claim 13, further comprising:

determining if the latest glucose value data is valid; and

if determined to be valid, storing the requested latest glucose value data locally and resetting the heartbeat counter.

15. The method of claim 14, further comprising, if determined not valid, resetting the heartbeat counter without storing the latest glucose value locally.

17. A continuous glucose monitoring system, comprising:

one or more processors; and

non-transitory computer instructions executable by the one or more processors, the instructions comprising;

iteratively receiving a heartbeat message transmitted by a receiver,

determining if it is time to request data from the receiver responsive to each received heartbeat message based on whether more than a predetermined amount of time has elapsed based on a heartbeat counter, and

obtaining glucose concentration data from the receiver if it is determined that it is time to request sensor data from the receiver.

18. The system of claim 17, wherein obtaining further comprises requesting a latest glucose value data and a current system time from the receiver, and uploading the requested latest glucose value data to a remote server upon receipt of the requested latest glucose value data.

19. The system of claim 18, wherein the instructions further comprise:

determining if the latest glucose value data is valid; and

if determined to be valid, storing the requested latest glucose value data locally and resetting the heartbeat counter.

20. The system of claim 19, wherein the instructions further comprise, if determined not valid, resetting the heartbeat counter without storing the latest glucose value locally.
