simple script for pulling data from US Freestyle Libre sensors from Android phones

Freestyle LibreLink Android Data Extractor/Exporter

This is a simple python 2.7 script for pulling data from an Android phone running LibreLink (US version) for Freestyle Libre sensor to CSV files on your PC/Mac (only tested on Mac). It does not require a rooted Android phone. LibraLink stores data in SQL database files. The script downloads the data from the phone, extracts the data, reads the SQL database for historicReadings, notes, and then merges them into a single CSV sorted by timestampUTC.

1. Install Android Debugger (ADB) by Installing Android Studio
2. Put your Android phone into developer mode, and connect to your PC/Mac via USB cable.
3. Open a terminal, and run adb devices to verify your computer can access the phone. You may need to confirm permission on your phone.
4. Run python extract.py. You will have to approve the backup operation to allow the script to copy the database files from your phone.
5. You can now load the created .csv files in your favorite data analysis/visualization tool. merged.csv is just the combined data.
