<div class="moz-cite-prefix">Yes, RAM on hw3.0 is very tight now.
Greg, you can save around 7 KB by not inserting an SD card.<br>
<br>
My normal free RAM is around 22 KB after mounting an SD card,
which normally still works if I take care not to stress it by
additional web / telnet sessions.<br>
<br>
Greg, if you enable debug log level for "webserver" and
"webcommand" you will get free RAM log entries on pages and
command calls.<br>
<br>
I'll try the latest changes as soon as I get home.<br>
<br>
Regards,<br>
Michael<br>

I’m a little worried by 30KB RAM free. That is tight, and it
doesn’t take much temporary buffers for output to cause it to run
out of ram. I did try it just now in my car, and it seemed ok for
me - but I was accessing it via AP from my iPhone.

<div class="">Anyway, Michael knows the webserver, so best to

<div class="">Framing errors would be indicative of a mux issue,
not really RF signal. Are you sure the modem is not browning
out from lack of power? Are you seeing any ..START.. messages
in the log (which is a modem restart)? I was getting a lot of
these until I switched to a powered USB hub. How are you
powering this - 5v usb or 12v?</div>
<div class=""><br class="">
</div>
<div class="">Don’t worry about the net manager interface
priority messages. Those are there because the wifi stack
keeps screwing with the default interface, so I work around it
by re-setting the default interface pretty much every time
there is wifi ap/sta event. For example:</div>
<div class=""><br class="">
</div>
<div class="">
<ol class="MailOutline">
<li class="">Start and Access Point + Station</li>
<li class="">Start a modem</li>
<li class="">Wait for everything to connect. Netmanager
priority will be Station.</li>
<li class="">Shutdown access point and station. Netmanager
will switch to modem.</li>
<li class="">Start a Station. Netmanager will switch to
station.</li>
<li class="">(at this point, everything is fine - but
network status shows a ‘dead’ AP interface left lying
around unused)</li>
<li class="">Stop the station. Netmanager will switch to
modem.</li>
<li class="">A second or so later, the wifi stack will
shutdown the station interface, and say ‘oh look, there is
an AP interface, let’s switch to that’. Server v2 can’t
connect any more.</li>
<li class="">Now, with my new code, Netmanager will pick up
on this and switch to modem.</li>
</ol>
<div><br class="">
</div>
<div>If I have time, I might change the Netmanager code to
only output the priority message if it actually has to
change the interface.</div>
<div><br class="">
</div>
<div>I don’t have any plans for changes in the next few hours.
At work now, lunch time over, and day job beckons.</div>

<div class="">Ok, interesting. Am I seeing an
out-of-memory crash? I can't tell...<br class="">
<br class="">
It seems like the webserver status button is the worst
offender,<br class="">
probably because it's doing a lot of work and building
a big payload. <br class="">
Very often hangs for a while before responding, and if
so, usually<br class="">
results in the job queue overflow. If I catch it
quick enough and hit<br class="">
home or some other shorter task, the overflow will
drain and I'll get<br class="">
the new screen; otherwise a crash. Sometimes there
will be a timeout<br class="">
mixed in. I'm wondering if our little squirrel in the
ESP32 just can't<br class="">
pedal hard enough...<br class="">
<br class="">
I did some tests going between wifi and modem, and it
seems to be better<br class="">
than yesterday. I am still having a lot of trouble
with modem framing<br class="">
errors. I get only an update or two (25-35 frames),
if that, before<br class="">
they start mounting, eventually relying on the 3
minute timer to reset<br class="">
things. Thought last night that perhaps it was
electrical interference,<br class="">
since there's a 2.4 ghz transmitter screaming right
under the modem<br class="">
board. But turning off wifi altogether (mode and
power) didn't change<br class="">
the framing errors, so that can't be it. Perhaps I'm
just in a bad (RF)<br class="">
neighborhood. The webserver status page (when I can
get it) is<br class="">
reporting -95 to -97 dBm for the signal. Seems a bit
low, but I don't<br class="">
have a lot of experience in that department. I'm just
using an antenna<br class="">
off my portable ham radio. Supposed to be good to
over a ghz, but not<br class="">
ideal, to be sure.<br class="">
<br class="">
There are a lot of "netmanager: interface priority is
pp3" messages when<br class="">
running the modem. Is that netmanager offering
encouragement to the<br class="">
modem, or an indication of some status that might be
bad?<br class="">
<br class="">
I've switched over to the home wifi, and will let it
run for the night,<br class="">
but can load another build before heading to bed in an
hour or so, if<br class="">
there is one.<br class="">

I’ve been doing a lot of bringing up and down wifi
and modem links, and switching between ap, apclient,
client, and off wifi modes. It seems that the
network manager is behaving better now (at least on
my desk). That bug of taking down mongoose would
have caused unpredictable behaviour and weird errors
everywhere.<br class="">

I’m going to put it in my car now, and leave it

Hi folks,<br class="">
<br class="">
Ok, so the new code seems to be working half-way
decently. But I think<br class="">
there's a memory issue with the webserver. After
poking at home and<br class="">
status a couple of times, my browser (chrome or
Firefox) drop from a<br class="">
nicely formatted screen to something very
text-like. Links and words,<br class="">
no buttons. Then another poke or two and the
module crashed. I've done<br class="">
it a few times, and the crash usually seem to be
with the Status button,<br class="">
which, looking at the console, seems to have an
auto-repeat on it. I<br class="">
managed to get the repeated "job queue overflow"
once, followed after<br class="">
hitting home a few times, a similar crash as
below.<br class="">
<br class="">
This was one of the quicker crashes (browser
didn't get to the text-mode<br class="">
state), using AP mode wifi. Browser in this case
was Chrome. I have a<br class="">
suspicion that the issue with the text-mode stuff
is a leak somewhere<br class="">
triggered by Firefox, with its CSS fetches.<br
