1. Hello everyone!
2. I am full beginner in ESP8266. I have a module ESP82 ESP-07.
3. I want to test the one in AT mode using Rtty software.First of all I connected the module
4. in according to this guide
5. [url]https://docs.espressif.com/projects/esp-at/en/release-v2.1.0.0_esp32s2/index.html[/url]
6. I have an USB/UART adapter (probably CP2102), and I tested it with a logical analyzer - it works correctly.
7. I used this firmware (v2.1.0.0)  for flashing:

9. I use a flash download tool V3.8.5 for flashing of my ESP8266.
10. But.. after flashing the module didn`t respond on AT commant at all.When I pressed enter - RttY software worked correctly - CR LF symbols appear in the UART. There was a very strange thihg - when I try to erase the meory, my laptoop (Win10) can not connect with the module (timeout error).But the firmware flashing soccessfully.I connected GPIOs in according to this image [url]https://riktronics.files.wordpress.com/2016/10/untitled.png?w=462&h=296[/url]
11. What did I wrong?

You're in the wrong forum here... this is for the ESP32 family of chips. You could try bbs.espressif.com instead.
