It shows the ESP12-S has the shortest pulse of all but also the ESP07-S does not wake up.

It is difficult to extend the pulse with by adding some resisors or else.
So there has been some schematic changes with result is this issues!

Here the 12-S module - wake NOT OK:

Here I did some comparison of different modules:

a) ESP01 - wake OK! b) ESP Wemos D1 mini with 12-F module - wake ok: c) ESP07-S - wake NOT OK:

Found this post which shows the that the S-modules has a missing resistor:

Can anybody explain?

You may get some help from this thread. https://www.reddit.com/r/esp8266/comments/jrj7s7/esp12_not_waking_from_deep_sleep/


Probably not the discussion is about the PullUps and PullDown at GPIO 0, 2, 15.
But thats not the problem.
It must be an other issue.

Is there a specification what has to ...

Dear Espressif Team,

i used ESP12-F module since years without having prolems getting up from deep sleep.

Now I bought some ESP07-S and ESP12-S modules and connected it with the same external circuit than I did for the ESP12-F since years.
