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.
Best OBDII?
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.

Apparently, the built-in controller in the ELM 327 dongle is responsible for whether it connects
with Chipset: MM32L073
works under Dudu6

My vGate vLinker MC+ had no problems getting paired via Android BT settings and I can use it on DUDU7 just the same way I used it on my previous FYT7862 unit: Mainly an app to monitor the DPF (VAGDPF) and secondly Carscanner. I have not tried to use it with the internal DUDU7 OBD stuff because i) I'm concerned that it would interfere with the above apps (I always need to disconnect one to use the other so afraid that DUDU just blocks other apps) and ii) DUDU7's OBD functionality seems rather basic (generic OBDII rather than car specific protocols) so not sure as regards benefit - fuel consumption etc is available in the car anyway. If DUDU7 could read/interpret the status of VW group DPFs incl. regeneration and gear box / clutch temperatures then I would sunset the other apps

I got the KUULAA OBDII. It is connected to the DUDU OS, but there is no data showing in the status bar or in vehicle information app. I test it with a third party app, and it works fine.
My car is 2007 Toyota Camry Hybrid.
Head unit 13” FYT.
OS DUDU 7862 V240927.
Kindly, if someone has a solution for this issue please share it.
ahmedjassm I have Corolla Hybrid and the only data that I get is cooling liquid temp and battery (12v) voltage.

I am getting the battery voltage even without the OBDII.
I think it is measured by the head unit, not sure.

I got VEEPEAK OBDII, it is works perfectly with Dr. Prius and Hybrid Assistance apps. But it doesn’t connect to DUDU OS.
I just want to share this with you in case you want to try these apps.
ahmedjassm I have Vgate vLinker Mc+. Same situation. It works perfect with Dr. Prius and Hybrid Assistant but I can't make it work with Dudu.
@"ahmedjassm"#p2796Yes. The host itself can obtain the voltage.
MihaiFlorin Because foreign OBD may be different from our domestic products, this needs to be matched according to the equipment. Tomorrow I will ask the developer if I can get some samples to match.
dudu-langzi
That will be greatly appreciate!
dudu-langzi I already provided a sample of vLinker MC+ to your team. But the devs said to have patience because it is not on the priority list at the moment.

I need a new OBD2. Mine is an old slow BT2 model.
Will OBDLink SX be supported anytime soon?
Should I wait for development, or order one of the adapters recommended in Telegram channel?

Can you share the list of adapters listed on Telegram please? I would like to buy one that definitely works!
