Looks good!<br>
<br>
I've switched wifi and modem on and off a couple times, it always
correctly reconfigured, with priority for wifi, and ota flash was
usable on all connections.<br>
<br>
I'll do some road tests later on.<br>

<div class="">I found and fixed an issue with wifi not attempting
STA reconnections in APCLIENT mode. That may have been the cause
of some of Greg’s issues.</div>
<div class=""><br class="">
</div>
Regarding Wifi and Modem co-existing, I think this is a similar
issue to what I saw with APCLIENT. Sometimes wifi doesn’t remove
the interface. There is also a race condition where an interface
is ‘up’, but has not yet been assigned an IP address (as is the
case with the ‘pp’ interface you show below).
<div class=""><br class="">
</div>
<div class="">I remain convinced that the correct way to deal with
this is to bind our source address to the preferred interface,
whenever we want to make an outgoing call. But, looking at the
mongoose library code they simply don’t seem to offer that
option. The standard socket API does, of course, have the bind
option after socket creation but before connect.</div>
<div class=""><br class="">
</div>
<div class="">LWIP does, however, seem to have an alternative: <span
style="color: rgb(58, 58, 58); font-family: monospace;
font-size: 16px; background-color: rgb(186, 205, 216);"
class="">netif_set_default()</span>. That function supposedly
sets the default interface to be used, unless one is specified
manually (presumably by binding the socket). I think we can have
net manager use that whenever modem/wifi comes up or goes down.</div>
<div class=""><br class="">
</div>
<div class="">Going down that route, I added it, but then found
some messy handling (in netmanager) of m_connected_wifi. That
would be set if either a STA or AP wifi came up, but that
doesn’t seem right. We don’t want to set default routes out an
AP link. So, I refactored that, and added a separate m_wifi_ap
flag in netmanager to track AP being up/down. Then, that
introduced a problem into MDNS as it was listening on
the network.wifi.up event (as it needs to come up both in AP and
STA modes), so I fixed MDNS to work like the others. I may
re-visit this tomorrow, as perhaps two new events ‘wifi.any.up’
and ‘wifi.any.down’ may be a better way to do this (rather than
the generic network manager messages we are using at the moment,
with the client then checking the flags to see which one came up
- wifi or modem).</div>
<div class=""><br class="">
</div>
<div class="">There is a new Info level output from ‘netmanager’
to show if it changes the default interface, and I extended
‘network status’ to show link status on interfaces, interface
numbers, and default interface status. This should give us some
more visibility as to what is going on.</div>
<div class=""><br class="">
</div>
<div class="">I haven’t managed to find the issue with wifi AP not
bringing down interfaces correctly.</div>
<div class=""><br class="">
</div>
<div class="">Overall, this was a fairly large re-factor, and I am
concerned about unintended consequences. I do, however, think
that the approach is right. I haven’t got cellular coverage at
home (almost midnight here) so can’t test modem connections.
I’ll take it for a drive tomorrow and try then.</div>
