Ludovic, welcome :-)<br>
<br>
you're right, can play is unfinished. It seems it wasn't needed up
to now, you're welcome to finish it. Mark would best comment on
what's missing there, as it was his concept & framework draft.<br>
<br>
Another local option is replaying a set of specific frame sequences
by scripts running series of "can tx" and/or "can rx" commands.<br>
<br>
Regarding dashboard development, you can simply add a random metrics
data generator to the UI. You can find templates for this in the
examples:<br>

<br>
Documentation of course can always be improved :-)<br>
<br>

<p>Hello everyone,</p>
<p>My name is Ludovic and I've just bought an OVMS for a R&D
project I'm working on. I know how to read/write some (easy)
code, and am not afraid of (digital) electronics too. I've
managed to compile, and flash FW to this unit.<br>
</p>
<p>My use-case is to use OVMS as an aid during the testing phase /
tuning of an EV vehicle:</p>
<ul>
<li>Using OVMS as a pure data-logger of the CAN Bus (to SD card,
with an automatic offload to a remote server as soon as a
network connexion is available) - i.e. logging during the
runs, and dumping the data either as soon as possible, or when
the vehicle is back in the shop.<br>
</li>
<li>Also making use of the "dashboard" functions to have an
in-vehicle display (phone/tablet) of the main parameters of
interest : GPS Speed, Motor RPM, some BMS parameters, some
controller parameters, ... so that the test driver can have
some feedback on the internals of the vehicle.<br>
</li>
</ul>
<p><br>
</p>
<p>Part of my plan is to explore the DBC-based vehicles of OVMS,
and for that I was interested in using the "replay mode" that
has been contributed to the code in 2019 :

; however it does indeed look like a work in progress - as I
wasn't able to make it replay something.</p>
<p>I've not delved much into the code (yet ?) but it looks that
some implementations are incomplete (like `<span
class="blob-code-inner blob-code-marker js-code-nav-pass "
data-code-marker="+"><span class="pl-en">canplay_vfs::InputMsg`</span></span>)
and could explain that. But first I wanted to ask here what was
your experience with this part - is it working for you in some
state, even buggy ?</p>
<p>"replay mode" is not absolutely necessary but could be a huge
time saver - otherwise I'd have to replay from another CANBus
transceiver - and I'd prefer an integrated environment.</p>
<p>"replaying" is interesting for the setup phase as I'll be able
to fine-tune the DBC setup ; have the metrics generated and then
have the dashboard displaying "live" data - without needing a
real vehicle test.<br>
</p>
<p><br>
</p>
<p>Also in the plan is to build a customized dashboard from a
chosen set of metrics. This looks easy and well documented as
far as I could tell, and I do not expect a lot of difficulties
here ; what do you think ?<br>
</p>
<p><br>
</p>
<p>Also part of the plan would be to have a way to log to
fixed-size files (either based on the number of events captured
on the CANBus ; or based on the duration of the capture - like
every 5 minutes) and to find a way to "rsync" them to a remote
server. I do not intend to use the "server" connection (be it V2
or V3) as my use-case is a little bit different and I need to
retrieve raw CANBus data, not processed metrics - for later
post-processing (with SavvyCAN etc...). I'm open to any advices
on the feasibility of this.</p>
<p><br>
</p>
<p>Finally, as a newcomer I'll also try to help with documentation
on things that I struggled with or that are evident but not in
the doc yet.</p>
<p><br>
</p>
<p>Thanks everybody who created (and contributed to) this project
that looks a fantastic tool to observe and tinker with vehicles!<br>
</p>
<p>Please feel free to share your thoughts on this.<br>
<br>
Regards from France,<br>
