Problem with Arduino Uno and ESP 8266 module

Juraj:
flashing the esp did work? (you write about firmware versions)

Yes, tried two versions of 0.9.5.2 AT (9600 and 115200 baud).

So flashing esp seems ok (no troubles/errors), but after that I can't communicate to my module in any way.

Below you can see connected ESP 8266 to PC via PL2303 to flash device:

However, while flashing firmware seems to work, I couldn't talk to my ESP using Arduino IDE serial monitor port - again, it doesn't respond to my AT command... well, AT command isn't even visible in that window:

Of course I picked correct COM port in Arduino IDE options, that's not a problem.

So my question is why can't I even insert simplest command "AT"? As I said in first post - no matter firmware version, no matter connection, no matter baud, no matter even supplying module -> got 3.3V adapter and still can't talk to my module.

Any help or tips would be truly appreciated :slight_smile:
