deep sleep need around 10uA

I saw some new functions in 1.4 (have not checked what we run currently) that you can use to stop the WiFi and use verry little power while mentaining operation

Markus

@Links2004

SDK is at 1.3

1.4 make problems hope 1.5 will do better

Me No Dev

@me-no-dev

yeah, I heard

slow loop as well

yeah, wififpm* functions are not in 1.3

#define FPM_SLEEP_MAX_TIME 0xFFFFFFF
wifi_station_disconnect();
wifi_set_opmode(NULL_MODE); // set WiFi mode to null mode
wifi_fpm_set_sleep_type(MODEM_SLEEP_T);
wifi_fpm_open();
wifi_fpm_do_sleep(FPM_SLEEP_MAX_TIME);
......
// wake up to use WiFi again 
wifi_fpm_do_wakeup(); 
wifi_fpm_close(); 
wifi_set_opmode(STATION_MODE); 
wifi_station_connect();

just one additional question to the time.ino:
there are two parts of the code. one in setup an one in loop.
Is the time in both parts picked from the ntp.server, or is it only read out from the internal clock?

Markus

@Links2004

the ntp server is called periodically (in background) to keep the internal clock correct,
all time functions use the internal clock.

brutzler

@brutzler

OK, set timezone to "1" for me to work (germany). But I am not sure, that daylight will be automatically?

Markus

@Links2004

I use configTime(1 * 3600, 0, "192.168.1.12", "192.168.0.1"); and it working fin. also Germany :)

brutzler

@brutzler

Using interal NTP?

Markus

@Links2004

yup, they are in sync with the PTB atomic clock.

brutzler

@brutzler

Router? or what device?

Markus

@Links2004

one router with openwrt + RTC one linux server

server is master

brutzler

@brutzler

will have a look, if my router makes ntp...

Markus

@Links2004

a fritzbox have it integrate for example

brutzler

@brutzler

Guess, what I have? ;-)

Markus

@Links2004

yup fritzbox is common in germany

brutzler

@brutzler

Just wanted to see this periodically update. Started wireshark, but I do not see any matching telegrams?

There is only one telegram on startup of the ESP:

10579    23:22:46.609658000    192.168.1.29    224.0.0.1    IGMPv2            60    Membership Report group 224.0.0.1

Markus

@Links2004

periodically not meany minutes the internal clock is good.

brutzler

@brutzler

Yes, but shouldn't be there a ntp-request on booting the chip?

Markus

@Links2004

yes if configTime is called ther shut be one

if you add Serial.setDebugOutput(true); you will see the sync info

brutzler

@brutzler

hmmmmm.... Code is working, I see the actual time in the console, but no telegram...
capturing filter is:

ip.src == 192.168.1.29|| ip.dst ==192.168.1.29

debug is on. what sync info do you expect?

I get this:

Connecting to WiFi
...scandone
state: 0 -> 2 (b0)
.state: 2 -> 3 (0)
state: 3 -> 5 (10)
add 0
aid 3
pm open phy_2,type:2 0 0
cnt 

connected with WLAN_xyz, channel 4
dhcp client start...
.ip:192.168.1.29,mask:255.255.255.0,gw:192.168.1.1

Waiting for time
please start sntp first !
.Fri Nov 27 23:29:28 2015

Markus

@Links2004

looks like working :)
i get the date + time one time Fri Nov 27 23:31:22 2015

brutzler

@brutzler

please start sntp first! Sounds not good

Markus

@Links2004

i dont get this, i only have configTime in my code.

brutzler

@brutzler

I use the original code from the link you provided. https://github.com/esp8266/Arduino/blob/4cf72e7ef4fcabde230de44ba1d1ab5d57cdeee0/tests/Time/Time.ino

Only made changes regarding to my WiFi

Markus

@Links2004

make sens based on the code.
in the first time call to check the time the time is not synced

brutzler

@brutzler

???

Markus

@Links2004

  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

@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
