    हिन्दी

I got a canbus with dudu4 mazda 3 2007

But the issue is it’s not detecting in about section and also while updating shows unkown.

About device

Canbus pic attached

Canbus debug shows the values are readable previously i was on older version of dudu os it was showing door info properly but after update to 3.6 OTA now it’s not showing


Here you can see Unkown then try to
Update

@dudu-lai can you please help?

Old version 3.5 shows like that

Using version 3.6, open/close the main driver's door 3 times and record a CANBUS log of the door information

Sure will do. Is there a solution of unkown canbus error?

Check is it a correct log?

    I enabled Use Canbus Beta and then enabled Export Canbus Log to TXT.

    haziqt You need to use the mobile phone camera to record the CANBUS log scrolling on the screen after opening and closing the main driver's door 3 times

      Okay

      Any update? @dudu-lai @DUDU-Meng

        haziqt Sorry, just saw the video today.
        The video is blurry and the data is completely unreadable!

          a month later

          the same issue : on previous no-name head unit (4core allwinner- 2/32) with can bus decoder Raise - I have info about doors and fuel consumption. but with new one DUDU 5 + the same Raise MZD 05 canbox - there no any data from canbus

          If enable can bus log - it is noticeable that there are data with doors opening, buttons pressing on wheel... but head unit reacts only on buttons.
