The best free car diagnostic apps for cars via ODB II?

Question

Android

The market for devices for diagnosing cars through ODB II is sad - a bunch of Chinese crafts that cannot read specific error codes, let alone reset them, and working devices for thousands of dollars. I suspect that with apps working through the ODB II bluetooth adapter? Who can recommend a free app that can read any errors on cars of the last years of production?

Answer 1

It's fantastic. Programs cost a lot of bucks not because of their complexity, but because they
know what the bytes they read mean. There is no standardization. Everyone comes up with
almost their own nuts and screws, so that only with a special wrench for 200 bucks can they be unscrewed.

Answer 2

The bluetooth adapter provides console tty access to interface commands on the obd connector.
he does not even suspect about the protocol itself and the transmitted data of the vaapche.
data processing, decoding errors, the formation of control commands and everything else is assigned to the program.
