I am not responsible to any damage to the sensor that might occur, use this at your own risk. This app is only intended for research. 6 | 7 | ### This app only works with non-US Libre 1 Sensors, if you have a US Libre 1 sensor this app will not work with it. 8 | 9 | ## Installation 10 | 11 | Apks are available on the Release tab here on GitHub. 12 | 13 | You can also build the app yourself: 14 | 15 | [This guide](https://androidaps.readthedocs.io/en/latest/EN/Installing-AndroidAPS/Building-APK.html) from the AndroidAPS docs explains how to build an apk, the steps should be basically the same, just using this repository instead. 16 | 17 | You'll need the Android SDK installed and define the ANDROID_SDK_ROOT environment variable, after that, you can run gradlew to build the .apk file (it should probably be signed so you can install it). 18 | 19 | You can also install Android Studio and build it from there. 20 | 21 | ## Usage 22 | When you open the app, you can select different options (Scan, Reset Age, Start...) and then scan the sensor, which will execute whatever you selected. 23 | When you scan the sensor to perform any action, you should wait for the second vibration to stop scanning. This might take a bit longer with operations which involve writing into memory. 24 | 25 | The "Dump Memory" option will dump 360 bytes of the sensor's FRAM to `sdcard/openlibrenfc/memory_dump.txt`, and the "Load Memory" will load that same file. If you edit that file, the checksums won't be checked, and it might send the sensor into failure if a checksum is incorrect. 26 | Make sure you have **backups** of previous memory dumps so you can restore it in case anything happens. 27 | 28 | -------------------------------------------------------------------------------- /app/src/main/res/drawable-v24/ic_launcher_foreground.xml: -------------------------------------------------------------------------------- 1 | 7 | 12 | 13 | 19 | 22 | 25 | 26 | 27 | 28 | 34 | 35 | -------------------------------------------------------------------------------- /gradlew.bat: -------------------------------------------------------------------------------- 1 | @if "%DEBUG%" == "" @echo off 2 | @rem ########################################################################## 3 | @rem 4 | @rem Gradle startup script for Windows 5 | @rem 6 | @rem ########################################################################## 7 | 8 | @rem Set local scope for the variables with windows NT shell 9 | if "%OS%"=="Windows_NT" setlocal 10 | 11 | set DIRNAME=%~dp0 12 | if "%DIRNAME%" == "" set DIRNAME=. 13 | set APP_BASE_NAME=%~n0 14 | set APP_HOME=%DIRNAME% 15 | 16 | @rem Add default JVM options here.
