Hi Mark,<br>
<br>
WPA2 PSK passphrases for WiFi need to be at least 8 characters. Do
the serial numbers have leading zeros?<br>

They’ll do pretty much whatever we ask them to do.

<div class="">I think that should set both the module default and
auto wifi AP passwords to the serial number of the module. That
will be on a label on the underside of the module.</div>

<div class="">You are correct: this is a connected car, with
possibly disastrous consequences should somebody malicious gain

I’ve asked the China side. Specifically:
<div class=""><br class="">
</div>
<div class="">
<ol class="MailOutline">
<li class="">Can you print serial number stickers
for these modules? I can provide design - and we
can print a large batch.</li>
<li class="">Then, during manufacturing, have one
step to enter serial number as password into
module, like:</li>
<ol class="">
<li class="">Flash</li>
<li class="">Connect terminal</li>
<li class="">QC checks</li>
<li class="">New step to type: config set
wifi.ap OVMS <serialnumber></li>
</ol>
</ol>
</div>

<br class="">
Just to double check: so we won't set the module
password, only the AP pass phrase?<br class="">
<br class="">
Has setting the module password any drawbacks?<br
class="">
<br class="">
I'm asking because I assume the SMS channel -as soon as
implemented- will also provide command access, which
would be open by default as well without a module
password.<br class="">
<br class="">
Setting the module password would secure the webserver
as well.<br class="">
<br class="">
