Task bug

Mikescotland

Some of the triggers work only with ObdII dongle but not canbus.
Example

Trigger RPM works only from obd dongle, ignores canbus readings. What's strange is that nowhere in the system we can see RPM value from obd, only from canbus, yet system ignores canbus.
Other triggers like door open work with canbus (of course, there isn't a payload for doors over ObdII dongle).

And another thing in reminders. What's warning type "speed limit warning (red screen warning)", there is no information on this one and no configuration options?
Also about reminders. The trigger options are almost non existent , tpms, door and that undocumented speed. Why no coolant temperature or anything else?

Many branded vehicles lack RPM data in their CAN bus systems, such as several Korean brands and China's Geely. However, OBD systems do include RPM data, as they utilize K-line data—which differs from CAN.
Red Screen Warning: As the name implies, when you exceed the speed limit or encounter abnormal tire pressure, the entire screen turns red and flashes with a semi-transparent effect.

DUDU-Meng "as the name implies". Quite condescending and yes I can read what's that. But what triggers it, that I don't know and you didn't provide the answer.

OBD protocols all include RPM information via a universal protocol.
Many automotive brands lack RPM data on CAN bus, and numerous RPM protocols are non-standard.

Mikescotland

DUDU-Meng lovely. But again, what, triggers that speed smart reminder?

Mikescotland

DUDU-Meng and for the sake of the true answer:
Speed and RPM on cars with canbus are standardised, mode 1 PID 0x0C is RPM (vehicles Europe after 2004, USA after 1996, China after 2011).
There is usually no KLine protocol in Europe / USA should not be even implemented in cars manufactured after 2008 (US, EU, AUS).
Kline might be present up to 2015 vehicles.
Obd dongles on cars manufactured after 2008 use canbus service 01 PIDs for RPM.
So, I don't think your answer is very much correct.

There's no need to deceive you about this matter. While it's true that many car models' CAN bus systems lack engine RPM data, they all include speed information.
The OBD protocol almost universally incorporates RPM data.
If you're skeptical, feel free to contact common CAN box manufacturers to verify this—they're experts in this field.
If a CAN box can't access RPM data, DUDU certainly won't have it either.

Mikescotland

DUDU-Meng I'm not skeptical. Just saying that OBDII after 2008 in USA and Europe and some other parts of world must use CAN instead of other protocols to communicate with the car. So while technically it's a different protocol, in majority part of the world it uses CAN pins 6/14. Hence all canboxes are connected to this line anyway, there is no reason not to implement poll / answer for RPM PID from obdII protocol, it just takes a few more lines of code.
To be precise - I tested today and 2$ ESP32 with a tranceiver has enough time to listen to the CAN payloads and on the side 4x per second polling the OBD PID for RPM. I also destroyed my ELM OBD adaptor and guess what, as it is a new cheap device, it doesn't even have other connection than CAN 6/14...
But, as I see majority of issues here is named "canbox not working", well, let's indeed leave it to experts...

If your vehicle model's CAN bus can retrieve RPM data,
you can select system integration via the OBD peripheral.
This allows any OBD-related data compatible with CAN bus system integration to be displayed.

Mikescotland

DUDU-Meng that doesn't answer my last post.
Plus, original question was that RPM task trigger only works with Obd dongle.

DUDU-Meng

Mikescotland Are you referring to the trigger conditions in the automatic tasks?
Using OBD RPM is also fine; we haven't developed a CAN bus-specific interface yet.

Mikescotland

DUDU-Meng seems like you completely not reading the queries, mate.

Yes, I'm referring to the automatic tasks menu. Fine, only OBD works for RPM now, understood.
In the smart reminders section, once again, what triggers the "speed warning" alert, there is nothing to be configured for this trigger.

DUDU-Meng

Mikescotland
Sorry, I didn't quite understand what you meant earlier.
If you're referring to the overspeed alarm, that doesn't seem related to RPM. When the speed alarm is activated, the screen flashes red and an audible alarm sounds.

Mikescotland

DUDU-Meng once again. What activates the speed alarm? What is the trigger for it? Or scenario?

DUDU-Meng

Mikescotland This feature utilizes Amap's SDK data to automatically detect the speed limit on the current road and issue warnings when exceeding it. It will be ineffective in areas where Amap coverage is unavailable or data is lacking.

Mikescotland

DUDU-Meng so basically again, only available in China. Repeatedly told, take a look at FCC car launcher which has all your features that are only available in China on DUDU, but working globally.
