<p>Soooo....</p>
<p>I've finally found time to test this again.</p>
<p>Basically the same behaviour as described below.</p>
<p><b>VWUP_OFF_TICKER_THRESHOLD 5 with 4 trys.log</b><br>
Car was locked initially. Unlocked the car before line 21 (around
time mark 60.000). Locked around time mark 80.000. Car stayed
responsive until line 108 (time mark 100.000).<br>
At line 130 (tm=116.814) I swap back to PollState=0. The poll for
PollState=0 gets an immediate reply (line 131-133) and therefore I
swap back to PollState=1.<br>
The weird thing is that line 132 (which got a reply) is exactly
the same as 126 (or 118 or 110) which didn't get a reply!?!? So
the car has no idea of the poll states as the data is the same?
There must be some issue/bug/behavior inside OVMS (maybe even in
the hardware buffer) which gets triggered by a PollState change.
Or the canlog-monitor uses somehow a cache and doesn't show the
messages immediately.</p>
<p><b>VWUP_OFF_TICKER_THRESHOLD 10 with 4 trys.log</b><br>
Same as below. One thing I've noticed though: Car was locked until
line 32 (tm=63.814). Then I've unlocked it and the lines 33 and 34
showed up immediately. This indicates a buffer/cache/etc. issue
with the canlog-monitor as well (imho).<br>

I don't see any obvious mistakes on a first check.<br>
<br>
Please do the tests again with CAN monitoring, so we can see
what's actually going on on the bus.<br>
<br>
An OBD device normally logs into the device sending a UDS diag
session command (0x10), then keeps that session alive by sending
tester present (0x3E) evers 30-60 seconds. See the UDS
documentation I sent you, or for an overview, see <a
href="https://de.wikipedia.org/wiki/Unified_Diagnostic_Services"

<br>
You should be able to get the session type and protocol by logging
what your VCDS does on the bus.<br>

<p>Attached are two logs. I haven't had the can-monitor active
unfortuantely..</p>
<p><b>VWUP_OFF_TICKER_THRESHOLD 5 with 4 trys.log</b><br>
As the name says it polls every 5 seconds in PollState=1 and
swaps back to PollState=0 after 5*4=20 seconds.<br>
Until line 35 you see the CAN errors as the vehicle is OFF.
Then I unlocked the car and in line 38 I get the first reply.<br>
Around line 90 I locked the car again. It polls, but gets no
reply, <u>but not error either</u> (?!).<br>
Line 118 sets the PollState=0 and suddenly a response comes
in. So in Line 123 I set the PollState=1 again.<br>
The the game starts again: Polls get send, no reply but no
error either. After 21 CarOffTickers I switch to PollState=0
and suddenly a reply comes in...</p>
<p><b>VWUP_OFF_TICKER_THRESHOLD 10 with 4 trys.log<br>
</b>Here I unlocked at line 57 and locked around line 100.
After that polls get send, no reply, <u>but errors happen</u>.
And the car is finally off.<br>
Although I've tried the same thing later that day and the car
didn't even go to sleep with Threshold=30!?!? So the behavior
is not 100% reproducible (yet)...<br>
</p>
<p>@gateway throttling: In VCDS (which - hopefully - does only
polling too) I have a little number showing me the refresh
rates of the values. It indicates ~8 refreshes per second. So
with 1 second shouldn't be any throttling.</p>
<p>@OBD "tester": I have no clue what this is ;) So if the
polling framework doesn't do it, I don't do it. All I do is in
the obd_eup.* files.</p>

polling may keep the car awake, that's also an issue on the
Kia e-Niro IIRC.<br>
<br>
Changing the PollState can only affect the car indirectly via
the changed polls. Maybe you could add your code & a log?<br>
<br>
Regarding the poll replies stopping, is that also reflected in
a CAN log? Maybe the OBD gateway throttles if it sees too many
requests? (Hopefully not…)<br>
<br>
If the gateway does throttling: do you login to the OBD as a
"tester" and keep the session active by periodically sending
the "tester present" frame?<br>
<br>

<p>Heya again,</p>
<p>I'm trying to develop a detection for when the car is
off/locked but I'm encountering a weird phenomena:</p>
<ul>
<li>Car is shut down and locked</li>
<li>OVMS connected</li>
<li>CAN poll for voltage (only one poll value active) with
30 secs fails with error (so far nothing weird)</li>
<li>Unlock the car via car-key remote</li>
<li>Poll succeeds and I'm switching from PollState=0 to
PollState=1 where I poll every 2 secs</li>
<li>Lock the car via car-key remote</li>
<li><u>After 1 hour the polls still work and the car is
active</u></li>
</ul>
<p>Is something like this known from other vehicles? So
basically my car never shuts down :(</p>
<p>Another secondary weird thing:<br>
When increasing the time to 5 secs for PollState=1 the
polls get no reply and after 20 secs I swap back to
PollState=0.<br>
BUT the second the PollState changes the car replies
again...<br>
Even more weirdness: When PollState=1 time is 10 secs and
I swap back to Pollstate=0 after 40 secs the same thing
happens! Immediately I swap to PollState=0 the car replies
again.<br>
As if the PollState switching somehow wakes the car up??!</p>
<p>Any ideas?</p>
<p>Soko<br>
