The problem really seemed to occur only after switching from Wifi to
modem, also tried with another SIM.<br>
<br>
I have now configured the Google DNS servers as well, will report if
I get the issue again.<br>
<br>
Another OTA issue, I haven't fully figured out yet: after switching
on the modem, the download will always go via modem. As long as Wifi
is available, it should be used -- maybe we also need to control the
default route?<br>
<br>
OTA modem download does not work from my server. First thought it's
Hologram (a single firmware update needs more volume than is covered
by the free developer plan), but it also does not work with my local
SIM with a high volume plan.<br>
<br>
I noticed a rather strange effect: when I let it run, the server
actually logged the download after 17 minutes, but still no download
progress on the console.<br>
<br>
I need to retry this with verbose logging on the gsm-ppp channel to
see what's going on.<br>
<br>

Michael<br>

I’ve added a ‘network status’ command. Can you try it, when you
get DNS errors, to see what the DNS servers are set to?

are from the ``make monitor`` command. As soon as
this sees a hex number scroll by that smells like
an address in the ESP32 memory map, it tries to be

Can these safely be ignored? The flashed

<br class="">
<br class="">
b) How do you get back to the factory
partition if something went so wrong you can't
use the "ota" command?<br class="">
<br class="">
I would have expected "make flash" to reset
the boot partition to "factory", as all
flashes are only done there, but it doesn't.<br

So if you're on another partition with a

a way to set the boot partition using
