- Fri Sep 29, 2017 8:26 am #70450 Thx, I've never used the RTC memory and haven't thought about it. So RTC memory survives reset via RESET but not power cycling / toggling EN? Good to know

This actually is also an argument to tie a physical reset switch to EN instead of RESET, because you would expect it to reset the whole state of the device... (at least I would)

- Fri Sep 29, 2017 9:55 am #70453 another good reason: pulling rst and chpd down sometimes leaves you with the chip drawing 0.6mA instead of only some µA ...

(...) sometimes leaves you with the chip drawing 0.6mA instead of only some µA ...

Sometimes? That's not how science works :p
It is not important for my application, I really don't need deep sleep or low power. The reset is only used for reset
However - for further projects - do you have any reference on that? I know that some ESP modules do have a pull-up on RESET on the module itself, so of course this alone will draw ~0.3mA if you pull it down to GND.

this indeed could be an explanation, never looked "under the hood" just recognized different behaviour and swaped module ...
