Soko,

nice progress :-)

If you can't detect vehicle state by listening to regular status CAN frames, you can check the time since the last poll reply in the per second ticker.

As poll replies normally come in fast, you should be able to detect a switch-off by a small timeout, say 3 seconds… probably need to add a counter, as a single poll may get lost / ignored.

CAN tx errors can be caused by other issues as well, so should generally not be interpreted that way.

But… are you sure there are no status frames on the bus? Have you done a can log or tried the re tool?

Regards,
Michael

Hi guys,

Want to report success on connecting and reading my VW e-Up via OBD cable using the Poller. As you can see in the screenshot of the log attached I get an IncomingPollReply(..) call and an SoC value of 33.333%

Once I turn of the ignition and lock the car though I don't get any replies no more (line D 793813) and then I get can1 errors... I'm polling with 10 seconds intervall.

I know that this is as it should be... but my issue is: I don't have any way to know if the ignition is on, the key is in, the car is running, the car is charging as the PIDs are not known for such values (afaik by the lists of sharkcow https://www.goingelectric.de/wiki/Liste-der-OBD2-Codes/).

So what would be the best approach to change the different polling states? Can I somehow get called (in my vehicle-class) if an can-error is thrown? Then I would increase the poll frequency.

Any suggestions?

thanks

Soko
