v3.6 Canbus Bug: Skip fwd rwd now is the same

gismo

[1] Describe in detail the error you encountered.

In v3.6 if you press Skip fwd OR rwd on VW Canbus SWC it always skips fwd. Skip on screen works normally.

Error not present in v3.5 - this is a new error.

[2] Provide a screenshot of the system information and take a picture of the system information in the pop-up window by long-pressing on the top-left image for 3 seconds in “Car Settings”-“About”.

[3] Is it possible to reproduce the error and what are the steps to reproduce the error?

Yes 100%

Canbus log (pressed 5x skip fwd and 5x skip rwd):

I will now downgrade to v3.5 as the bug is too annoying.

gismo

I couldn't downgrade, sadly - see https://forum.dudu-auto.com/d/876-duduos-36-beta-released-just-in-time-for-chinese-new-year/94
So I've done more testing:

The error affects VW PQ and same gen (Polo before 2019, Golf6, etc)
Error does not affect MQB and same gen (Golf 7 etc). When I select those, Skip works fine. But then I loose door status, PDC etc as my T6 is PQ.

@dudu-lai appreciate your thoughts. Everything worked fine in v3.5 for VW PQ and now it's broken. And I can't downgrade without factory reset apparently.

liamstears

I can confirm I have this same bug for VW PQ, I hope dudu engineers can fix this asap...

dudu-lai

OS version 3.6 is not an official version and will be updated in the future. the CANBUS service is different at each date and will have to wait for an update in a subsequent version.
Temporary solution: Downgrade back to OS3.5 or update the CANBUS service separately.

This fix works perfectly, Thank you

Slavus

dudu-lai on 3.6 beta2 cannot be installed.

DUDU-Meng

Slavus 3.6 beta2 Is this still an issue?

Slavus

DUDU-Meng Yes, it is. The file shared on this thread cannot be installed because of "App not installed as package conflicts with an existing package."

DUDU-Meng

It's because the version number of the installation file is lower than the one built into the system.
The system does not allow downgrading the installation

Slavus

DUDU-Meng Yes, i know that. Issue is still present.
