Thanks for sharing this. This is an excelent project. I am testing this using a laptop with Windows 10 and a Bluetooth ELM327 (Probably a clone) but I am not able to make it work. I see the ELM327 is paired in bluetooh and two COM Ports are created (COM3 and COM4) but I cannot connect to either of those in the ddt4all software.

I know you recommended an USB ELM327 and W10 is not mentioned, just wanted to check if you have any recommendations.

I can also run this in Linux Mint and try to buy a USB ELM327.

Can you please recommend a USB ELM327 dongle that you know works with the software? Any additional recommendation to run this in Mint?

Thanks!
