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><div class=""><br class=""></div><div class="">This is what it looks like for me, tonight:</div><div class=""><br class=""></div><blockquote style="margin: 0 0 0 40px;
