About ATCF on Freematics OBD-II UART Adapter V2.1 (for Arduino)
Posted: Wed Feb 10, 2021 7:06 pm
Hello,
I've been using the Freematics OBD-II UART Adapter V2.1 (for Arduino) in one project and it works well with a standard OBD2 vehicle.
I tested the standard code available on two cars and the reading went as expected.
However, from what I could understand from the tests I did, the vehicle I have to use in the project is not an OBD2 standard.
I saw that this reader has the ATCF function that allows you to change the header. I searched on the codes and was unable to find such a function.
From what I've been studying about OBD, the default header is 7E8, the header of the vehicle I'm using is 7AB.
So I wanted to change the reading header using the ATCF function for this header that I have and see if I can read the vehicle information through the OBD port.
Does anyone have any tips or solutions for this?
I appreciate the attention.
