DUDU-Meng Hello, are you able to advise on the issue of me not being able to set my speedometer back to mph? As I believe it was caused by the updating then downgrading of my firmware?

BBishop123

DUDU-Meng hi, just installed this new one and having the same issue with the launcher refreshing constantly, and a/c controls not working at all.

Unfortunately, issue still persist after a short standby delay (ACC Off).

Geruda32 Have you had any issues with your digital speedometer unit settings? Are you able to switch from kmh to mph and vice versa in vehicle settings? For me the option to set it to mph has disappeared completely and has left my digital speedometer stuck in kmh.

Hi,
No, i'm in France and my car is set in stock to Km/h.
You have to replace SMEG/NAC Unit (just connect old radio and screen), or use PSA Diagbox to switch to MPH unfortunately.
Don't know why it set by self to Km/h after downgrade...

Why not try upgrading to the latest 251121 system?

BBishop123

Geruda32 Yeah thats what I thought :/, thanks

Geruda32 managed to get it. In mph and the fuel unit setting is now mpg

Mpg is now back as an option for fuel unit settings. I still don't know why it disappeared. But was able to get it to come back by reattaching the oem stereo and screen and changing it in the oem settings. Ridiculously complicated procedure to just change the units of my speedometer.

Latest version fixes logo and Citroën model screen flickering issues. Navigation bar functionality can now be tested.

DUDU-Meng Is that the 3.7 beta? Or the file you gave us in this thread? As I tried the file you gave us and had the launcher refresh bug.

DUDU-Meng And where can I get the latest update? Is it on OTA yet?

Geruda32

DUDU-Meng
Thanks, installation successful, waiting if issue fixed.
Will feedback if reappears.

Geruda32

DUDU-Meng
Still there, unfortunately :/

I've received Hiworld PAF1.21, i'll try if the issue happens with this canbus box.
What do you recommand for better support, Raise or Hiworld ?

Geruda32

DUDU-Meng
Wouldn't it be easier if DUDU OS took a "snapshot" or "buffered" the A/C settings before sleep, and then restored them on wake-up?
This way, when the device wakes up, the controls and values are still available and displayed, giving the CANBUS box enough time to retrieve the A/C information from the BSI.
Is this feasible?

DUDU-Meng

Geruda32
The current logic is to read information in real time.

Geruda32

DUDU-Meng
Ok…
I've seen on the internet that this issue is "maybe" related to a bug in the CANBUS box firmware, where it doesn’t retrieve the A/C information after a short ACC cut-off (it starts too fast and doesn’t have enough time to receive the HVAC CAN frames).
And apparently, this issue is fixed in the latest firmware of this CANBUS Box.
Is it possible to get the latest CANBUS firmware to try?

Still no solution ?
Very strange that in very specific condition, Raise CANBUS does not receive HVAC CAN Frame.
On my vehicle, after wake up, i can see HVAC trame on displayed CAN print log, but values remains blank.
But this behavior is very random ...
Is it really no possible to put in cache A/C info before sleep and restore in wake up ? This gives enough time to the CANBUS Box to retrieve the HVAC frame and get the A/C status.
Or a fix that force CANBUS Box to "wake up" HVAC and send data.
It will be definitively fix this issue (i think).
Or if you can have and share the latest PSA-RZ15 CANBUS firmware to try first...
Thanks

DUDU-Meng

Geruda32
Have you tried updating the CAN bus box's firmware?

Geruda32

DUDU-Meng
No, i can’t find firmware for my canbus box.
My seller doesn’t answer...
If you can provide me the firmware, i can test 🙂

DUDU-Meng

Geruda32
You can take a photo and send it to @dudu-lai for assistance with the firmware.
