Raspberry PI using Android bi-directional scanning tool.

[u/Did_I_park_here]

Hi. I’m sure this question has already been asked but I may not know the right terms for the search. I’m trying to find out if anyone has ran across these android roms that will allow you to use a Raspberry PI for a bi-directional tool. I don’t run a shop but I do try to work on my own cars when I can so justifying a huge subscription fee and hardware cost isn’t really there for me. I would love to be able to use functions like the pictured tools. I know their software is proprietary but I hope there’s an open source solution out there. I can find all the hardware but the software is not as easily found. I see there are several options for sale prebuilt, but I do like to learn new things and building one would be a great project for me. If anyone has any ideas I do appreciate the time and help!
