Deep Sleep delay issue

[yellowsky]

Hi everyone,
i use ESP Easy but i have i issue with the deep sleep delay.

If i use a deep sleep delay > 1 hour (i.e. 3600 s), the esp module reboot each hour. It works well for delay < 3600 s

In my case i would like a reboot each 6 or twelve hours (depending the application).

Anyone has the same issue?

Deepsleep uses an internal 32 bit counter in uSecs. So i would expect it to be working up to 4294 seconds. I think this is bound to hardware limitation where the internal circuitry uses a 32 bit counter to wake up the main system.

Ok, thank you.
Maybe put this information in the wiki.

Do you know a way to use external device to achieve that?

Depending on the sensor, you could use ultra deep sleep: http://www.esp8266.com/viewtopic.php?f=11&t=4458

Done.

Perfect.

But i thought to a low power timer device to wake up the pi each x seconds where x is > at the limit.
Is anyone know that, could you give me a reference (it is for a battery powered project.
Thank you

You could also wake it up manually by pulling RST to GND, and using a deepsleep time of 0. Then it will never wakeup automaticly.

Dont know if this is feasible for your project.

[yellowsky]

No it is not possible while i would like an automatic measurement once a day.

Wouldn't it be possible if we had a dump variable that let you use Deep Sleep Delay X seconds (maximum 4294) and let the ESP wake up after y number of Deep Sleep Delay Cycles.

If deep sleep delay is 3600 seconds and deep sleep delay cycle is 24 then the wake up would happen once every 24 hours?

Just a thought.

Default value for cycle is 1 for backwards compatibility.

hm... not sure about that.
The deep sleep timer is an internal ESP8266 thing.
For an additional variable you have to wake up the ESP and go back to deep sleep.
The more this variable has to be written to the flash to keep it.

I know some timer chips but they are programmable up to two hours.
A solution might be using a CD4060 but this is not really low power
and not very precise.

Maybe an idea:
I just took a look into one of my timer clocks.
It is made of two PCB's, the clock itself and power supply/relay board.
It should be possible to use the clock part only, it just has Vcc/Gnd/Out.
As it is just a standard LCD clock it should not take too much power
and can be set felxibly to any wanted time.

this would be possible via rtc memory. such a wakeup would also take very little time.


this can be a post 2.0.0 feature.

also you can just wakeup the esp manually by setting deepsleep to 0 and pulling RST to gnd to wake it up.

Great news! Glad to have been of some kind of help.

Indeed, i found some information about rtc memory but to be honest i won't be able to program it.
How is it possible to ask this feature? Of course, it is dedicated for low power usage (to boot without wifi and check if the sleep is stillpending or not).

[budman1758]

No idea how to implement it but perhaps support for this module could help with long delay issues. A new plugin maybe?

Looks like it has a multitude of features.

Like i said before in this thread: use ultra deep sleep en connect the ds3231 SQW to the CH_PD pin according to the attached layout. Now you only need to program the ds3231 to activate the SQW pin: https://forum.arduino.cc/index.php?topic=139955.0

Post an feature request on github for it.

Yeah we could even make it easier for the user: Just let the user specify the actual sleep delay they want. If its longer than the max sleep time of the ESP, then wake up every ~4 hours until we can do the final sleep after which we do our task.

Yeah let's not confuse the users. Love simplicity and ESP Easy is getting closer to perfection with each commit! Good job all developers.
