I am new to the ESP8266 and try to find my way.
As I newbie I flashed my ESP-01S (1MB) through the Arduino IDE with some examples and and it worked fine.
Now I want to make use of the AT commands but had problems finding the right firmware.
All links on the Espressif website lead to ESP32 firmware. Did I overlook something ?
Finally I found :
https://github.com/sigmdel/other_releas ... esp01s.zip
and tried to flash it with
esptool.py -p /dev/ttyCH341USB0 -b 115200 write_flash -e -fm qio -ff 80m -fs 1MB 0 /../espat_221_esp01s.bin
but i always get the following response / error :
esptool.py v4.8.1
Serial port /dev/ttyCH341USB0
Connecting...
Failed to get PID of a device on /dev/ttyCH341USB0, using standard reset sequence.

What do I do wrong ?
The ESP-01S Module is ok, I flashed it again with the Arduino IDE ...
I am using the ESP8266 PROG : https://joy-it.net/de/products/SBC-ESP8266-PROG
which has a small switch to choose between UART & PROG.
I assume after the flashing of the AT Firmware was successful that I could
type in AT commands and get a response. Is my understanding correct ?
For now it does not work ...
Thanks a lot for your support !!!
