I doubt someone sells an esp with the one month old AT firmware 2.1.
the firmware update is same on esp-01 as on esp-12. you need and USB-to-TTL-Serial adapter, some wires and resistors.
it is easy to flash the firmware to an esp dev board like Wemos because the USB adapter and the required wiring are on board.

but they didn't built a version of AT 2.1 for esp-01. I have it here
https://github.com/jandrassy/UnoWiFiDev ... T_V2.1.zip
The flashing command of AT2 with esptool is Code: Select allesptool.py write-flash @download.config
I recommend to change in download.config file flash_mode to dout

and the commands reference

Hi, I have got myself a usb programmer for the ESP-01
Is there a none python command line way of updating the firmware, it looks quite messy when I looked into that? I have seen videos using software called "ESP8266 DOWNLOAD TOOL v3.4.4" could this be used, if so which bin files would you flash as there are a number of them with the AT 2.1 firmware
Thanks in advance
