glukose-service's Introduction

glukose-drivers-java

Java glucomenter protocol service implementation using Reverse Engineering Hacking techniques

Hacked Devices

FreeStyle Optium Neo Glucometer from Abbott

Sniffing Tools

The sniffing tool used for reverse engineering the glucometer device protocols is the Windows tool called USBTrace

The application uses

[Usb4Java library] (http://usb4java.org/) version 1.2.0: Library to access USB devices.

Installation

Create a USB rules (60-freestyle-optium-neo.rules) on your Linux Box directory(/etc/udev/rules.d) using this script, you only must change the group name used when you start your node app.

ATTRS{idVendor}=="1a61", ATTRS{idProduct}=="3850", SUBSYSTEMS=="usb", ACTION=="add", MODE="0666", GROUP+="miguel"

Refresh udev to reflect changes with the command: sudo udevadm trigger

Execution

The service have two parameters:

-p: indicate the path where we must export the json result of the service. Default path the same directory where we start the service.
-w: the wait time (in milliseconds) between the send a command and receice the result from the device. Default time is 1000 ms

An example could be:

java -jar glukose.jar -p /opt/glukose/export -w 1500

Result

The result of the service have a JSON format to be consumed by the app glukose. The file created have this name: [Device Serial Number]#[Created time].json

An example could be LAGV041S04629#20160225234331.json
