OBD2 K-line Reader (ISO9141 and ISO14230)

[Kalhankaran]

Hello, I would like to extend my congratulations and thanks to you for your successful, exemplary, and inspiring projects that broaden people's horizons.

I would like to request your assistance regarding your "OBD2 K-line Reader (ISO9141 and ISO14230)" project.

I know how to upload files to the ESP32 as a file system. However, there are multiple .ino files in the web_server folder, such as functions.ino, K-Line.ino, SPIFFS.ino, WEB_SERVER.ino, and WebServer_Code.ino. They all seem to be interconnected.
I couldn't figure out which .ino file to upload. Could you provide support

Hello. Thank you for your feedback. I'm glad you want to try my project 🙂. It doesn't matter which file you open, just open the one .ino file and hit the upload button. The Arduino IDE will navigate how to upload all the files. All .ino codes should be in one folder. Basically, the main file is WebServe_Code.ino as the name of the folder. After you try I expect results from you if everything works. Some people had tried it but it didn't work for them. I think it is from their car because I had tried all the protocols with several cars and it worked for me without a problem.
