If only I had my Mii already…<br>
<br>
If the OBD port is shielded from the CAN traffic, you need to poll
some device. ECU = Engine Control Unit = device 01.<br>
<br>
I would suspect the basic car status info to be available from
device 09 (central electrics), but it seems no PIDs have been RE'd
from there yet. So maybe you need to derive the info from some other
mode/status register.<br>
<br>
It's bad needing to continuosly poll to get the live status data. Is
possibly another, unfiltered CAN bus available at the OBD port?<br>
<br>

<p>Ahhh OK, I've found OvmsVehicle::virtual void
TickerXXX(uint32_t ticker);<br>
Got it! This was exactly my issue as I didn't know about any
function which gets called regularly so I could check something
like this...<br>
It's not an ideal situation though: I just can slow down the
poll after my fail-counter gets too high as I need to check when
the car gets powered again. So all I can do is polling, lets say
every 60 secs when the car is off, and increase it once its on.
But there is now way around this 60-sec polling if the only
thing I can do is poll :(<br>

<p>Afaik there is only the sharkcow's list below, reverse
engineered by him from ODBeleven.</p>
<p>(dev)marxx exlpained to me: There is a gateway between the
CAN-Buses and the OBD Connector in all VW-AG vehicles which only
replies to polls and also acts as security gateway if you want
to write to the buses.</p>
<p>So I think I cannot really do a can log or use re tool as the
OBD interface stays quiet if I'm not polling it...</p>
<p>And as there is no other vehicle from VW,Seat,Skoda,Audi,etc.
in OVMS. So I have no cheat-sheet :(</p>
<p>Anyhow... I would need to poll one ECU (is this the correct
therm?) which doesn't shuts down... or maybe the issue is the
OBD-gateway shutting down.<br>
</p>
<p>What do you think?</p>

Soko,<br>
<br>
nice progress :-)<br>
<br>
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.<br>
<br>
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.<br>
<br>
CAN tx errors can be caused by other issues as well, so should
generally not be interpreted that way.<br>
<br>
But… are you sure there are no status frames on the bus? Have
you done a can log or tried the re tool?<br>
<br>

guys, <br>
<br>
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% <br>
<br>
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. <br>
<br>
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 <a
class="moz-txt-link-freetext"
href="https://www.goingelectric.de/wiki/Liste-der-OBD2-Codes/"
moz-do-not-send="true">https://www.goingelectric.de/wiki/Liste-der-OBD2-Codes/</a>).
<br>
<br>
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. <br>
<br>
Any suggestions? <br>
<br>
thanks <br>
<br>
Soko <br>
