Why does AT command don't work with ESP8266-01?

Question

i have a problem with my new ESP01. I tried using AT commands with the baud rate of 115200, but don't receive OK answer. I also tried to flash it and didn't quite succeed as it's just flashing that never ends (treid for about 10 minutes).

Setup I use:

1. ESP8266-01
2. USB A to UART
3. TeraTerm

What I get:

1. When baud = 74880:

2. When baud = 115200:

I will really appreciate your help...

Answer 1

I solved it by flashing my ESP01 with this firmware and using CoolTerm instead of TeraTerm.
