[Bug Feedback] Problem with A/C Control and Navbar (Peugeot 308 T9)

Geruda32

Hi, my device information:

On Latest DUDU OS 3.6E Beta.

I have an issue with A/C Control on Navbar (Peugeot 308 T9 2014, Raise Canbus Box, RZ-PSA15).

When unit turn in sleep mode and wake up for couple of hours, i can't be able to control A/C with navbar, the button does not respond (and message "A/C Control not supported"):

I have to open A/C Pop-up and change temp to recover control:

After changing temp, A/C Control is recovered and i finally able to control A/C on Navbar again:

If i don't do this, i can't control A/C on Navbar, and message "A/C Control not supported" appears when i try to change values directly on Navbar.

Is it possible to fix this ? Save the state of A/C Control before sleep to quickly recover ?

Thanks 🙂

Another question:

For front defrost, when i press this button:

A/C Pop-up open to show information, which is very good.

But for Rear defrost, nothing happens:

Rear defrost is activated, but pop-up don't show.

Is it possible to fix that too ?

Thanks 🙂

Defrost pop-up window: When you run the air conditioner in full-screen mode, check the settings in the upper right corner to see if the pop-up window function (defrost) is enabled.
For the navigation bar issue, try manually installing this app. If it still doesn't work, let me know.

Hi,
Tried your APK but nothing change, i can't change temp on navbar until i open pop-up window and i change a values to activate A/C Control.

APK is installed succesfully:

After restart head unit, same behavior:

I have to open A/C Control panel and change a value to enable A/C control (and navbar control), and i must do this every time after the device wake up (after sleep)..

For rear defrost, i've checked all options in settings and all are enable, but i can't see "Defrost" function:

This is all enabled function in Pop-up window (first option "Etat climatisation" is enabled on unit", just uncheck for testing):

DUDU-Meng does this apk only work for Raise canbus or also SimpleSoft canbus? I have the same car and nothing works with the new layout, but I have Simplesoft.

Hi,
APK installed succesfully but no change after reboot:

There's a small improvement: I can activate the control panel by pressing the A/C button or changing the blower speed, (changing temp doesn't work), but I'd like the panel to activate and synchronize/retrieve A/C status upon startup or wake-up...
I think the A/C control panel isn't retrieving the air conditioning status information upon startup or wake-up. If it could retrieve it, that would probably fix the problem.

Seeing the system information, the CANbus you have selected is RZC brand. May I ask if the CANbox hardware is RZC or another brand?
Do you have any photos of Canbox?

Please install this APK and set two positions according to the picture to test the protocol with two switches and shutdown mode.
Then turn off the engine, turn off the power, and wait for 1 minute to turn on the power. Starting from the process of turning on the black screen, use your phone to shoot a video. When you enter the system, there will be a floating message of danger. Record an additional 15 seconds.
Finally, please send me the TXT file in the picture and the video taken with your phone. Thank you

We have received the LOG. Thank you very much.

DUDU-Meng

Can you display the door information?
Please go to Factory Settings - Test Protocol - Turn on Protocol Log Printing Switch, and a floating log will appear on the screen.
At this point, use your phone to shoot a video of the physical panel's air conditioning buttons being operated.
Send the video to me.

There is another issue: the navigation bar does not go into sleep mode and cannot be controlled. From which version did this issue begin? Which previous version was functioning normally?

Hi,

for this issue, i don't know why it's happening ... Aside the A/C controls, navigation bar working well for me ...
New air panel support for Peugeot 308 T9 start in this beta (3.6E)
Maybe a bug related to 3.6E Beta ?

There the video from canbus log print and physical button pushed:

Hi,
After installation and reboot, A/C values appears instantanely and i can control with Navbar (i've try couples of reboot to be sure), very good improvement !

But same issue after couples minutes of deep sleep (ignition OFF), when i wake up HU, values disappears (--°) and i can't control A/C, until i change values in A/C Panel or i push A/C physical buttons.

Another issue, for vent control, when i set vent OFF (below 1), it stay on 1 (instead of 0).

If the vent control display 1 and i go lower, vent correctly turn off but it stay on 1, instead of 0.

All other issues have been resolved, and there is also a problem where the sleep wake-up air volume is 0 but still displays 1, right?
Sleep.
