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>
</blockquote>
<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="">
