resoldered (see the picture). My soldering skills are not the greatest - sorry for the ugly picture. Unsoldered the resistor (red circle in the top right) and cut the conductor (left circle)
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.
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.
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.
