Michael,

<div class="">The impacting issue I am seeing is that new users
are coming onboard our platform, and the first thing they do is
upgrade to the latest (3.2.014) during the install process. They
then get continuous crashes. The CAN bus errors shown in the car
are also very scary. I think it best to replace 3.2.014 asap. My
only concern is if there is anything newly broken in 3.2.015.</div>

<div class=""> OK, followed on my server.<br class="">
<br class="">
It would have been an option to first let the users with
issues test the edge version. But I think the release
should be OK, crash statistics of the current version
look much better so far.<br class="">

I’ve tagged, built, and released to EAP, 3.2.015 -
based on head of edge.

<div class="">Not sure if this is generally releasable

<div class="">The subsequent poller
rework has enabled the Leaf to direct
polls to the correct bus, allowing the
PID polls originally defined (but not
working depending on the car state) to
function when the vehicle is on or off
and charging. Also the
IncomingPollReply code was tidied up
and aligned with that used for the
Twizy. The vehicle poller extra frame
request delay was also originally
fixed at 25ms uneccessarily slowing
down large replies such as the battery
cell voltage responses, now set to 0.
These changes mean the polling for the
Leaf is now working as it should.<br
class="">
</div>
<div class=""><br class="">
</div>
<div class="">The current edge version
appears to be stable and allows PID
polling reliably to both buses without
causing crashes. I have been running
it for 24h with 6 start/stop events
without issue. </div>
<div class=""><br class="">
</div>
<div class="">If others agree could
3.2.0.15 be staged for EAP release to
move Leaf users off 3.2.0.14? A note
could be to 3.2.0.14 stating there is
a known stability issue on the Leaf
and to use 3.2.0.15 or similar.</div>
<div class=""><br class="">
</div>
<div class="">GlynHudson and others on
other Leaf models can test to ensure
we are back to a stable release with
the required polling functionality
working. </div>
