Thanks TD-er, but that doesn't explain the problem in my environment :|

Can confirm the reset is now working as expected
I have got exact module as in this picture. Can flash firmware and sketch with flash mode as DOUT. But it runs just after flashing the sketch. After power off and on cycle it stopped working. NO REST is working so I guess I have to apply your fix to my ESP.

Could you please share the full image of your hack, as this image is just a part of whole picture?

Thanks

abhinavg, my modules are slightly different from akellai's picture shown, but I have the same issue: RESET function is not working.
Image


I found the following: there is an additional 6k resistor in reset line (I don't know why is neccesary) between EXT_RSTB and RST pin of 8pins connector.
After I remove and put a jumper back its place, RESET function is working well again.

Image
Orange line shows the connected points for RST.

I plan to use this ESP-01 for my thermostat project with battery, programmed by Arduino IDE, so I need deepsleep function. After several hours programming I realised the reset problem.
Modules ordered from EBay (seller is h-quality_electronic). I've already sent a message to the seller because he described a different version from what I received.

I've attached a picture about my ESP in original state (resistor which should be remove is marked with red circle).

I hope this information could help.
Regards,
aquariushu

I guess that should be documented on the Wiki.
This may cost people a lot of time finding it.

Looks pretty clear and concise to me. :geek:

Is there a new problem with the PUYA chips that does not work on the nightly builds made for Puya chips?

hi,

i cannot get it working with domoticz.
flashed the firmware, see the configpages of the esp-01.
use the same settingas with some other esp module's and i cannot get the output switching,
got the correct idx and the gpio-0.

any thoughts ?

You need to connect the switch to ground since GPIO-0 needs to be set to high for boot.

Or how do you connect it currently?

connected it wit jumper wires on a bread board.
the CH_PCD connected with +
it boots because i see the lets controlit easy esp webpage.

it looks like it doesnt understand the command from domoticz : http://172.16.200.230/control?cmd=GPIO,0,1

Yes but how do you connect the switch? Will it (when closed) pull the value on GPIO0 down to ground?
