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.

Transmitting analyte data using low-power instruction sets

In one embodiment, a method for secured communication between a medical sensor and a computing device includes receiving, by the medical sensor, an authentication request from the computing device. The method includes generating, based on values provided in the authentication request, a challenge-response message for the computing device. The method includes receiving, from the computing device, a responsive challenge-response message. The method includes verifying that the responsive challenge-response message includes an expected value and corresponds to an expected format. The method includes, in response to verifying the responsive challenge-response message, sending a sensor secret value to the computing device.
