I got the Libre 2 yesterday and immediately went about patching the Librelink App. I read the information here:
https://androidaps.readthedocs.io/en/latest/EN/Hardware/Libre2.html
This was the patch I used:
Instructions in English are below the German ones. I ran into a problem where 4 files ending in “.orig” had to be removed from the unpackad app after patching. Otherwise the repack step “apktool b” would fail.
So far it’s been working like a charm. I enjoy having only the Libre 2 with no external transmitter. It’s also nice to get the factory-calibrated values. I can still calibrate if needed, so I get the best of both worlds.
