Best OBDII?

ahmedjassm

Hi,
I want to get an OBDII for my car, but I don’t know which one is compatible with DUDUAUTO OS.
I have on my list Autel and XTool.
I need something with live data sharing and compatible with the OS.

Thanks in advance for any recommendations!

I'd like to get some recomendations too. I have an old ELM327 that I bought on Aliexpress back in 2017 and that I'm failling to connect to the unit. Outdated and probably fake (if that is a thing), considering it was $3.49

I saw in the telegram forum that kuulaa bt4 works well with dudu7. I purchased one but am waiting for delivery.

erik530 thanks Erik, I will check it out.
And please, let me how it goes with you when you get it.

USB is the fastest, however I don't think supported in Dudu (yet?)

From my experience the best, fastest and most reliable is genuine OBDLink LX (Bluetooth) and SX (USB).

The SX being USB means that torque pro connects everytime, no issue. It is the fastest of any OBD interface.

Which OBD category must be set in the OBD settings for the OBDLink LX?

Is there a list of supported OBD dongles? It would be very helpful...

rille I ordered XTool ODB2, but it is not arrived yet.
I will share the details, and if it is compatible with the OS when I get.

I tried vLinker MC+ and FS, both doesn't connect. But they work without problems with Car Scanner App installed at the DUDU7. Why are they not supported directly? I can choose ELM327 in the Devices -> OBD menu but it doesn't work. And no list with working dongles. It's annoying and in this way a useless feature.

I hope receiving the XTool obd this week, I will try it and post the feedback.
Thanks for your feedback.

EML327Can be used

dudu-langzi How? And which ELM327 dongles are working? Bluetooth BLE, Classic Bluetooth?

rille I saw some posted on telegram that recommended Kuulaa odb2, and they claim it is working with DUDU OS.
But I am not sure about.

rille eml327 obd After plugging in the car OBD interface, find the peripheral, OBD, in the desktop launcher settings, and then select Bluetooth binding.

I read here (https://www.carscanner.info/choosing-obdii-adapter/):

Never buy this “bad” adapters:
...
Adapters of brand “KUULAA”.
...

I would be nice to have the coolant temp in the status bar. So I have to start an extra app (Car Scanner). But Car Scanner can much more (e.g. oil temp).

rille

I did it this way, it doesn't work. The OBD dongle is listed but it doesn't connect. I tested with vLinker MC+ and iCar Pro 2S, both support Bluetooth LE. You should have a list with working devices... It's the same as with the CAN adapters. No list which adapter is working and the one suggested by support chat is also crap.

Same for me. Previously on the 7862 unit, and now on the dudu7 unit.
The elm327 is there, it is found by BT, but I simply cannot pair it. It works fine with my phone and previous 2 phones.

rille

It works with Car Scanner installed at the DUDU7. But the integrated OBD feature doesn't work.

elm327 working when I connect to bluetooth in the android settings (not BLE) for 3rd party apps, but it doesn't work in DUDU OS.

To get it working in the OS I had to connect it through the OS settings in the ODB section, but then it doesn't work with 3rd party apps.

It's normal that the OBD dongle can be used by only one software. Did you get your dongle (which one is it?) to work so you can display sensor values from OBD in the status bar or in the widget?

McFive05

Apparently, the built-in controller in the ELM 327 dongle is responsible for whether it connects

I use this
