Hello together,

i have a problem.

I am using some ESP8266-01 and it is always possible to flash a new sketch with Audiono-IDE.
But now i had ordered some new ESPs and i got a new version of the ESP-01 --> the ESP-01s.

And with this ESP-01s i am not able to flash them via Auduino-IDE.

For flashing i use the following adapter:

I tryed a lot of different settings about the flash-memory, because the ESP-01s has 1MB-Flash instead of 512k on the ESP-01.

Is there someone how has an idea what i can do to flash also the ESP-01s???

Thanks
Martin

Why many different settings if only the memory size is different?
if you have windows, try Espressif Flash Download Tool. it can detect the parameters.

I have three of those exact chips, i just use a ftdi or my esp8266-202 to flash them via the Arduino IDE, they work at any memory setting from 512 to 4mb and they come with At command software, just set your Serial to 115200 and test with AT for a response. FYI these chips have no reset button or whatever so you need to pulse them off/on with the power prior to flashing it so it's in the right state and the correct pin config for flash mode.
