Software not connecting to ELM327 BLUETOOTH

Post by black_lucifer » 23 Jun 2022, 23:56

Hello guys! First of all, thanks for giving us an opportunity to change our cars settings in an easier way! Congratulations for the software development! :)
I am trying to connect my ELM327 bluetooth adapter with the MMCondingWriter just to change some configs in my ETACS, but I'm having some problems... the youtube tutorials that I have watched, I learned that I have set this values in MMCodingWriter to be able to successfully connect to my ELM327 BT adapter (ELM parameters: port - auto; timeout - 150; baud - auto AND write blindly = On), I'm trying to connect with this configuration and many other possible configurations (for example: changing the boud of COM ports etc) but i am not able to connect anyway, the software seems like an infinite attempt, with the green bar scrolling forever and nothing appears in the output console. BUT when I change the COM port configuration (Autoboud option) from "auto marked" to "auto NOT marked" and chose the exit COM5 port, the software try to connect to my elm327 and show that message "ELM not found on COM5; Unable to start exchange session". Is there some configuration that I'm missing? My car may not be compatible with the software? Can someone help me with this problem I will be very thankful :)

Here some more detailed information about my models and equipment versions:

My OBD2 adapter: ELM327 BLUETOOTH V1.5 DOUBLE PCB CHIP PIC18f25k80 OBD2
My car: MITSUBISHI LANCER 2015/2015 AT (CVT) 2.0 4B11
My computer: Notebook DELL Inspiron 15 3567 - Windows 10 Pro 64Bits

kolyandrex, thanks for replying me! Yeah, I checked my ELM327 adapter to see if it is fake or true (using this article for help https://cvtz50.info/en/elm327/), the components and other circuit stuff seems original on my ELM327. The thing is, I have checked if my ELM is connected and ready to work using the software that you made available through this link (https://cloud.kolyandex.su/index.php/s/IV4GR9j0ovl2XaD) and according to the documentation that you made, the response from adapter, should be "ELM327 V1.5", but I got "OBDII v1.5" as response instead :| This might indicate that my ELM adapter is fake?

у меня кстати та-же проблема. но, я протестировал в ELM identifire, адаптер проходит все тесты и работает без нареканий с любым телефонным софтом. Хотелось бы подключиться без покупок нового адаптера.
у вас программа эту строку проверяет (респонз от ATI комнды) ? может есть какая-то возможность не погружаясь в перепрошивки устройств на ком портах обойти эту проверку?

чтобы не выбиваться из топика вот тоже самое на английском)
By the way, I have the same problem. but, I tested in ELM identifire, the adapter passes all tests and works flawlessly with any phone software. I would like to connect without buying a new adapter.
Does your program check this line? maybe there is some possibility without plunging into flashing devices on which ports to bypass this check?
