Hello. Im tryping to make a OBD2 project with my Lexus GS300 2001 with a ESP32 and ELM327 bluetooth adapter 2.1. I want to use your lib to connect to the ELM327 and retrieve RPM values; but which code do i use exactly to do this?

In the sketch. There are 4-5 sketches that run together for this project. In case you want to read rpm or etc.. It's all about interpretation with elm327. I suggest you read more info about elm327 at command. Or you can simply try elm327 bluetooth with Bluetooth terminal app and see how it responds. If possible, i suggest you test your elm327 2.1 via obd2 app on store and see if your adapter is really compatible or works with your lexus car. Since it MFY 2001, it might not be compatible with OBD2
