Everyone,<br>
<br>
I've pushed a change that needs some testing.<br>
<br>
I had the issue myself now parking at a certain distance from my
garage wifi AP, i.e. on the edge of "in", after wifi had been
disconnected for some hours, and with the module still connected via
modem. The wifi blob had been trying to connect to the AP for about
two hours.<br>
<br>
As seen before, the module saw no error, just the server responses
and commands stopped coming in. I noticed the default interface was
still "st1" despite wifi having been disconnected and modem
connected. The DNS was also still configured for my wifi network,
and the interface seemed to have an IP address -- but wasn't
pingable from the wifi network.<br>
<br>
A power cycle of the modem solved the issue without reboot. So the
cause may be in the modem/ppp subsystem, or it may be related (in
some weird way) to the default interface / DNS setup.<br>
<br>
More tests showed the default interface again/still got set by the
wifi blob itself at some point, overriding our modem prioritization.
The events we didn't handle up to now were "sta.connected" and
"sta.lostip", so I added these, and the bug didn't show up again
since then. That doesn't mean anything, so we need to test this.<br>
<br>
The default interface really shouldn't affect inbound packet routing
of an established connection, but there always may be strange bugs
lurking in those libs.<br>
<br>
The change also reimplements the wifi signal strength reading, as
the tests also showed that still wasn't working well using the CSI
callback. It now seems to be much more reliable.<br>
<br>
Please test & report. The single module will be hard to test, as
the bug isn't reproducable easily, but you can still try if wifi /
modem transitions work well.<br>
<br>
Mark, you can check your server logs for history messages with
ridiculous time offsets:<br>
<blockquote><tt>[sddexter@ns27 server]$ cat log-20190903 | egrep "rx
msg h [0-9]+,-[0-9]{4}" | wc -l<br>
455283</tt><br>
</blockquote>
The bug now severely affects the V2 server performance, as the
server is single threaded and doesn't scale very well to this kind
of bulk data bursts, especially when coming from multiple modules in
parallel. So we really need to solve this now. Slow reactions or
connection drops from my server lately have been due to this bug. If
this change doesn't solve it, we'll need to add some reboot trigger
on "too many server v2 notification retransmissions" -- or maybe a
modem power cycle will do, that wouldn't discard the data.<br>
<br>
Thanks,<br>
Michael<br>

Mark, please wait.
I may just have found the cause for issue #241, or at least something I need to investigate before releasing.
I need to dig into my logs first, and try something.

I haven't had the time to look in to Markos pull request, but from a first check also think that's going too deep to be included in this release.

Anything people want to include at the last minute, or can we go ahead and build?
