I got myself such a bluetooth adapter for my car, because the display on the radio stopped working, and I wanted to see if it will show up any errors. There are even apps for Android that work with said bluetooth adapter.
My question is, are the Android apps reliable, meaning, would they show as much data as a PC software would show when connected to the bluetooth adapter?
Also is this adapter good for all kinds of diagnostics regarding the car? What are the differences between that one, and the more expensive ones with cable for diagnostic (I've seen some for more than 100$, and the bluetooth one I got is just like 13$)?
