Are AP and STA still constrained to use the same channel?<br class="">

Michael,

<div class="">Really good. I had a quick run-through, and it seems
to work. I have some factory modules here that I can try this
with.</div>

<div class="">A couple of minor suggestions:</div>

<div class="">The only thing that worries me is the Wifi. I spent
this week looking through the code I wrote months ago, and given
what I know now, it is really not optimal. In particular, the
way it works (with one primary mode) does not now seem correct
(given what we know about the wifi stack now). I have now
re-worked the wifi driver to work as follows:</div>
<div class=""><br class="">
</div>
<div class="">
<ul class="MailOutline">
<li class="">The wifi stack is powered up in ESP32
WIFI_MODE_APSTA. That allows us to have a STA, an AP, both,
or neither.</li>
<li class="">The STA settings are set completely independently
of AP settings. So, a STA mode is set (off, scan-only,
promiscuous (scanning-client), SSID, or SSID+BSSID).</li>
<li class="">The AP settings are set completely independently
of STA settings. So, an AP mode is set (off, or SSID).</li>
<li class="">We now track the different modes and statuses,
independently.</li>
</ul>
</div>
<div class=""><br class="">
</div>
<div class="">This gives us a number of advantages:</div>
<div class=""><br class="">
</div>
<div class="">
<ol class="MailOutline">
<li class="">We can do a SCAN even when an STA or AP
connection is up. This causes about 2 to 3 seconds of loss
of connectivity, but doesn’t seem to kick anyone off.</li>
<li class="">We can turn on/off a STA connection, without
affecting the AP at all.</li>
<li class="">We can turn on/off the AP, without affecting the
STA connection at all.</li>
<li class="">The STA code is much more symmetric, and scanning
handled better.</li>
<li class="">We can (in theory) have a scanning STA
promiscuous client, combined with an active AP. I’m not 100%
sure of the practicality of this (as I think the scan will
affect the AP while it is ongoing), but it should be
possible to some extent.</li>
</ol>
</div>
<div class=""><br class="">
</div>
<div class="">The new code (and modes) is working for me, along
with some new commands (wifi client, wifi accesspoint). I am now
trying to convert the old commands to retain backwards
compatibility (but I would like to deprecate those, long-term).
The ‘auto’ system also needs conversion (but again, I’m trying
to make it backwards compatible).</div>
<div class=""><br class="">
</div>
<div class="">I should be able to get to a level where I can
commit (and push) today, for you to have a look at.</div>

<div text="#000000" bgcolor="#FFFFFF" class=""> I have
just pushed the first version of a setup wizard.<br class="">
<br class="">
It currently consists of five steps:<br class="">
<ol class="">
<li class="">Secure module access (configure wifi AP
and module password)<br class="">
</li>
<li class="">Connect module to internet (switch to
Wifi APCLIENT mode)</li>
<li class="">Update to latest firmware version</li>
<li class="">Configure vehicle type and server</li>

</ol>
I tried hard to avoid any dead ends and simplify the
process as much as possible, but need your help to test
if I really handled all potential screw-ups.<br class="">
<br class="">
I developed and tested the whole process on my 3.0
hardware module, so if you've got an unused 3.0 module
you can use that for the test without destroying your
car configuration.<br class="">
<br class="">
The wizard state is kept in config module / init, with
states "1" … "5" = steps above + sub steps suffixed, and
"done" being the final state. There is currently no
"back" option, but you can simply set the config
variable.<br class="">
<br class="">
You can start at any point, regardless of the
configuration already existing. The wizard will also not
change configuration options it doesn't need to touch,
so you can run it also on an already configured module.
But it's really meant to be a first init wizard, and
thus won't be a standard menu option.<br class="">
<br class="">
It only shows if module/init is not "done". If you try
the new version on an existing module, you won't see the
wizard until you do:<br class="">
<ul class="">
<li class=""><tt class="">config set module init ""</tt><br class="">
</li>
</ul>
…that's because the previous "password/changed" variable
is migrated to "module/init=done".<br class="">
<br class="">
The wizard is offered on the home screen if init is
empty. It automatically loads after login and from the
home screen when started, but it does not block the UI.
You can use all UI pages normally, to return to the
wizard, simply click the home icon.<br class="">
<br class="">
Logging is currently maybe a bit excessive, especially
as it's on the info level. That is to be able to get
some debug info also from modules in default
configuration.<br class="">
<br class="">
Regards,<br class="">
Michael<br class="">
