Nearly 2800 frames per second is quite a lot, and most is on can1
with many frame periods at 20 ms. Yet the total processing time
averages at 30-40 ms, so there is no actual CPU capacity issue for
that amount of frames.<br>
<br>
@Derek: can you please supply these statistics for the Leaf in drive
mode as well?<br>

<br>
Simons car sends at least 91 process data frame IDs on can1 and 84
on can2. Worst case would be these come all in within the shortest
possible time span, that would mean the queue needs to be able to
hold 175 frames. I'd add some headroom and round up to 200.<br>
<br>
But keep in mind, if the Incoming processing actually occasionally
gets blocked for up to 60 ms -- as indicated by Simons statistics
--, the queue may need to be twice as large.<br>

<br>
Actually we do know that, or at least have some indication, as we
count the CAN transceiver queue overruns. That info is included as
"Rx overflw" in the can status output & as "rxovr" in the logs.<br>
<br>
Adding a filter before queueing the frame would exclude the filtered
IDs from all vehicle processing. I meant adding a filter just to
exclude IDs from the timing statistics, assuming those are the
culprits, as Simon wrote the issue only appears after enabling the
timing statistics and printing them. That's why I asked if printing
might need to lock the statistics for too long in case of such a
long list.<br>
<br>
Completely blocking ID ranges from processing by the vehicle should
normally not be necessary, unless the Incoming handler is written
very poorly.<br>
<br>
<br>
Yet, if we add that, a mutex in the CAN RX callback must be avoided,
or would need to be non-blocking:<br>
<br>
<blockquote type="cite">
<div>The only real concern is thread safety between checking and

</blockquote>
<br>
A mutex like that could block the CAN task, which must be avoided at
all cost. I introduced CAN callbacks for vehicles & applications
that need to react to certain frames as fast as possible, e.g. to
maintain control precedence, so cannot use the standard CAN listener
mechanism (frame queueing).<br>
<br>
The current poller callback use is OK, if (!) the atomic type really
isn't the culprit, ie doesn't block.<br>
<br>
So if (!) an ID filter needs to be added before queueing, it needs
to be done in a way that needs no mutex. But I don't see an issue
with the vehicle passing a fixed filter when registering with the
poller/buses. The filter doesn't need to by mutable on the fly.<br>

OK, I've got a new idea: CAN timing.<br>
<br>
Comparing our esp32can bit timing to the esp-idf driver's, there
seem to be some differences:<br>
<a href="https://github.com/espressif/esp-idf/blob/master/components/hal/include/hal/twai_types_deprecated.h#L75" target="_blank">https://github.com/espressif/esp-idf/blob/master/components/hal/include/hal/twai_types_deprecated.h#L75</a><br>
<br>
Transceivers are normally tolerant to small timing offsets.
Maybe being off a little bit has no effect under normal
conditions, but it has when the transceiver has to cope with a
filled RX queue. That could be causing the transceiver to slide
just out of sync. If the timing gets garbled, the transceiver
would signal errors in the packets to the bus, possibly so many
the vehicle ECUs decide to raise an error condition.<br>
<br>
Is that plausible?<br>
<br>
On why the new poller could be causing this (in combination with
too slow processing by the vehicle): as mentioned, the standard
CAN listener mechanism doesn't care about queue overflows. The
poller does. `OvmsPollers::Queue_PollerFrame()` does a log call
when Tx/Rx tracing is enabled, that could even block, but
tracing is optional and only meant for debugging. Not optional
is the overflow counting using an atomic uint32.<br>
<br>
The atomic types are said to be fast, but I never checked their
actual implementation on the ESP32. Maybe they can block as
well?<br>
<br>
@Simon: it would be an option to try commenting out the overflow
counting, to see if that's causing the issue.<br>
<br>
Regards,<br>
Michael<br>

<p>Yes, I can confirm I've had one experience of the Leaf
switching to Neutral while driving, with a yellow warning
symbol on the dash. It refused to reselect Drive until I had
switched the car off and back on. Derek wasn't so lucky and
he need to clear fault codes before the car would work.</p>
<p>On returning home, I found OVMS was not accessible over a
network. I didn't try a USB cable. Unplugging and
reinserting the OBD cable caused OVMS to rejoin Wi-Fi.
However the SD logs showed nothing from the time of the
event. CAN writes are enabled, so it can perform SOC
limiting.</p>
<p>My car has been using this firmware since 21st November,
based on the git master of that day. As a relatively new
user of OVMS (only since October) I don't have much
experience of older firmware.</p>
<p>Perhaps a safeguard should be implemented before releasing
a new stable firmware that will be automatically downloaded
by Leaf owners. But I don't have the expertise to know what
that safeguard should be. Derek's suggestion of 'only CAN
write when parked' appears to be a good idea.</p>
