We delayed the release due to the CAN bus crashing issues initially
assumed to be related to the new poller:<br>
<ul>
<li>Simon Ehlen (Ford Focus Electric, in development)<br>
</li>
<li>Derek Caudwell (Leaf)</li>
<li>Chris Box (Leaf)</li>
<li>Developer from Jokela (Leaf)<br>
</li>
<li>on Github: Jaroslav Horak, with detailed bus analysis by
Richard Taylor (Leaf)</li>
<ul>
<li>→

</li>
</ul>
</ul>
<br>
I've lost track of the current status of the different issues &
investigations. My current impression is, none of the tested
software/config changes actually had any impact.<br>
<br>
Richard Taylor found out the Leaf issue with boots & reboots of
the module is triggered by the switched off SN65 transceiver. But
it's still unclear why that happens, why a terminator doesn't help
and why it only seems to affect the Leaf (what about the Ford Focus,
Simon?).<br>
<br>
So this points to some hardware issue, possibly something more on
the Leaf than the OVMS side.<br>
<br>
The SW changes meant to minimize SN65 off time are not yet complete,
there's a Housekeeping init change to be tested & possibly added
(see github issue).<br>
<br>
<br>
Did the changed CAN timing to better follow the SAE recommendations
actually have any benefits?<br>
<br>
I currently don't think so. Developer From Jokela posted:
<blockquote type="cite">
<pre wrap="" class="moz-quote-pre">After this change poller now sends tx commands, compared to before when it did not.</pre>
</blockquote>
… but that claim didn't match the statistics and wasn't confirmed.<br>
<br>
Simon, is it correct the poller filter additions solved your issues,
and the changed timing didn't have any effect?<br>
<br>
Richard still needs to test the timing change, but the Leaf issue is
clearly correlated to boots/reboots.<br>
<br>
<br>
So, does/did anybody see any positive effect from the SAE timing
patch?<br>
<br>
Besides the SN65 control enhancement, is there anything else open
that needs to be included in 3.3.005?<br>
<br>
Thanks & regards,<br>

<br>
I'd say release 3.3.005 is due. 3.3.004 was 03/2024, we've since
collected quite some fixes and new features, including extensions
for Smart EQ & the new MG4 support. There are lots of new
Smart users now, as Mercedes have stopped support for the official
Smart EQ App (see
<a class="moz-txt-link-freetext" href="https://www.smart-emotion.de/article/415-mercedes-discontinues-smart-eq-app-3rd-party-community-app-takes-over/">https://www.smart-emotion.de/article/415-mercedes-discontinues-smart-eq-app-3rd-party-community-app-takes-over/</a>).<br>
<br>
The current state is also very stable, I had no issue reports.
<br>
<br>
Any objections / open fixes or additions that should be included
in 3.3.005?
<br>
<br>
Regards,
<br>
Michael
