Obd II

Mikescotland

Gabe1321 did you buy a Dudu obd?
If so (or if it's a compatible obd adaptor) obd data in Dudu os (like speed etc) are when you pair your device via Dudu os "Device connection" menu.
If you want to use it in torque etc, you need to pair the adaptor via Android Bluetooth, "about device - Android settings - Bluetooth" and then choose the right adapter in the torque settings.
But here's the catch - you cannot leave this paired to both, only one at any given time (obd adaptors can serve only one connection).

I will try and I'll let you know the results. Thanks

Gabe1321

I just tried with no success. I disconnected it from dudus os and then about device android settings bluetooth pair new devices when scan it's there but can't communicate with dudu obd

Mikescotland

Gabe1321 torque? Did you see and set this obd dongle in torque settings as well?

Gabe1321

As can't pair it torque app doesn't find the dudu obd

Gabe1321 If your phone has previously connected to an OBD device, DUDU will be unable to connect. The OBD's Bluetooth can only connect to one device at a time.
If the connection is successful but the app doesn't work, please verify that the selected OBD type matches your OBD model.

On android Bluetooth When scan to find new device it finds dudu obd but I can't connect it. I disconnected my phone Bluetooth on the headunit to have the headunit find dudu obd which it do but like I said doesn't connect it

Please do not attempt to connect to OBD using methods we do not support. We can only connect to OBD protocols through the Settings > Peripherals menu.
If you use other connection methods, we cannot provide technical assistance.

Gabe1321

Apologies for the inconvenience. Can you please explain the process step by step again to be on the same page

Go to Settings - Device connection - OBD. You will see "change Bluetooth pairing device" and press DELETE
Go to Settings - about device - Android Settings - Bluetooth - pair new device. Press on OBD BLE and PIN is 1234
Go to torque - settings - obd2 adapter settings - connection type set to Bluetooth and choose Bluetooth device - choose Dudu obd (it may appear twice here, choose the first one).

All working after a while.

To pair it up back to Dudu os - Android Settings Bluetooth - tap on the sprocket wheel next to the device and "unpair".
Go to device connection in Duduos and pair it back to the os.

Gabe1321

I just did exactly the process that you told to follow still doesn't connect

Please stop going in the wrong direction. @Mikescotland has already uploaded the usage instructions for you. Connect via the OBD function, not the system Bluetooth. OBD uses the BLE protocol, which requires an app for protocol integration. Even if you could connect via system Bluetooth, where would you get the data?
Please double-check: Are you unable to locate your OBD device within the DUDU Settings > OBD function?

Gabe1321

Look DUDU-Meng here's what I found after many tries I got 2025 version dudu obd which on this i did exactly the procedures and didn't work and I got the elm 327 mini (blue one) and on this i just followed all the procedures that you show and works right up which makes me think that the new module needs some kind of update or something because when I bought it the ad was saying that was compatible with other apps also just to emphasize

Gabe1321
Are both of your OBD devices failing to connect?
You can plug in the OBD, go into the OBD settings, select the OBD model, and search for Bluetooth. Please record a video of this process using your phone.

Gabe1321

Only the recently module(2025) the elm 327 is ok but I will record it

Gabe1321

I can't upload video less than 150000kb how can I do my phone doesn't take video less than hd

You can upload it to a cloud storage service and send the link.

DUDU-Meng My problem with OBD is that the media finds the device but cannot get information from it (OBD is not on DUDU)
Here you can see a clip:

You selected DUDU OBD 2025, but the name appearing in your Bluetooth search is different.
You may have connected to another Bluetooth device.

The Bluetooth name for DUDU BOD 2025 is OBD II.

DUDU-Meng I select elm327 and this device is still displayed, but there is no connection to it, on the other selection options it simply cannot find any device.
The device, by the way, looks the same as yours, only with a different name.

The strange thing is that the OBD is found by bluetooth on Android but it cannot connect to it, when I try to connect the device to the application that is responsible for it, it also does not find it in bluetooth

I have also ordered a DUDU OBD, to see if there will be a change with it

Mikescotland

benzol let's clear a few things.

The blue dongle you've got I will NOT connect to duduOS obd. Only BLE devices would which this one (I have a second similar) isn't. It can work only in standard android Bluetooth on DUDU and 3rd party apps like torque.
Dudu OBD is BLE and will connect via connection OBD in the DuduOS. If you don't see it then:
A. the dongle is paired either to android system Bluetooth on DUDU
B. the dongle is paired to your phone
C. the dongle is defective.

When in proximity of the powered on DUDU OBD dongle, check: Android Bluetooth on DUDU (system one in android settings), your phone Bluetooth. If it's showing as paired in any of this, unpair it.
To avoid such mix up and frequent pairing / umpiring, pair Dudu obd to Dudu os, and blue one to android Bluetooth. They would work alongside, no re-pairing necessary.
