  while (!time(nullptr)) {
    Serial.print(".");
    delay(1000);
  }

the time call triggers the messages please start sntp first !

so basically the check if the sync is done is triggering the msg

@brutzler

OK, you think the stuff is working, but why do i get no telegram on wireshark?

Markus

@Links2004

ther musst be one. will sniff my self.

brutzler

@brutzler

arrrggg.....forget it. how to sniff WLAN?

Markus

@Links2004

wireshark + (lowlevel driver or linux) , or use tcpdump at the router.
wireshark can decode wlan when you know the key.

Mario Mikočević

@mozgy

I have RasPi on wlan for that :)

Markus

@Links2004

openwrt on the router make it easy too, call tcpdump and you are done.

brutzler

@brutzler

haha ... openwrt. Only a Fritz with AVM-OS

Markus

@Links2004

yes hidden webinterface :)

brutzler

@brutzler

more input pls

Markus

@Links2004

fritz.box/cgi-bin/webcm?getpage=../html/capture.html

brutzler

@brutzler

Raspi is somewhere around. Any Howto for this?

Markus

@Links2004

no need use the url and you can capture as wireshark file

brutzler

@brutzler

Fritz tells me: URL not found. Redirected to main page.....

@Juppit

Hi, the sntp makes an request on start, and about one hour later, nearly one hour. Then you see a new timestamp with Serial.setDebugOutput(true).

Markus

@Links2004

try fritz.box/html/capture.html

shut look like:

brutzler

@brutzler

ahh better... never seen this. will need some time to get it working

Markus

@Links2004

press start an it will work ;)

brutzler

@brutzler

haha ..... a lot of "START".

Markus

@Links2004

wifi ?

brutzler

@brutzler

still five ;-) AP or HW

Markus

@Links2004

AP Schnittstelle 0

brutzler

@brutzler

OK, working.

How can I post an image?

Markus

@Links2004

C&P it in

will work for any file.

Dmitry Kireev

@kireevco

@brutzler or upload it somewhere and post a link via markdown ![]()

C&P doesn’ work for me - mac client

brutzler

@brutzler

a little bit different to yours

Markus

@Links2004

other fritzbox :)

brutzler

@brutzler

I am sure. You have one with only 2,4GHz ?

Markus

@Links2004

can make images of 5 different when i want, reinforced concrete ins´t good for wifi.

it was a 7270 5Ghz disabled

brutzler

@brutzler

OK. using FritzBox nearly over 10 years, But never seen the capture possibility ....shocked....

Markus

@Links2004

its not linked in the normal web interface, its a hidden debug feature.
you can capture all internet traffic with it, very useful for debugging IoT thinks and reverse engineering

brutzler

@brutzler

What is the difference between "AP Schnittstelle 0" and "AP Schnittstelle 1"

Markus

@Links2004

AP 1 is the "gast" wifi when aktive.

brutzler

@brutzler

ok, needful background. Looks like I will have to search for a doc/howto regarding this feature, to complete my documentation

@Links2004 you earned a bear for your help. What part of D r u from?

Markus

@Links2004

Mario Mikočević

@mozgy

bear ? oh my :)

brutzler

@brutzler

Kölsch or Alt?

Markus

@Links2004

Kölsch

@mozgy: how do you sniff with a RasPi?
Want to have a look at the other side too

brutzler

@brutzler

Just found one of my RasPis with Wlan-Dongle. Should be enough hardware
