Arduino UNOUno and ESP01 cant: can't issue AT commandcommands

I would like to connect an Arduino UNOUno and an ESP 01 module. I use the Arduino IDE and I tried to test comunicationcommunication via serial monitor,. I get the "ready" message from the ESP 01, but I am not able to issue AT commandcommands from the serial monitor. It only insertsdisplays random characters toon the console.

It seems that no new linenewline character is issued, because if I try to insert mode commands, they are inserted next to previous characters. I use "Both NL & CR" and 115200 baud settings in Arduino IDE. Tried alsoI tried 9600 baud too, but then the text is unreadable.

I used folowingthe following pins on my ESP-01:

Vcc -> 3,3V
Gnd -> Gnd
Rx  -> Tx(pin 0) of my Arduino, used voltage divider to make it 3,.3V.
Tx  -> Rx(pin 1) of Arduino
CH_PD -> 3,.3V

Please see screenshot of Serialserial monitor screenshot:

EDIT: PROBLEM RESOLVED:

My arduinoArduino is connected to my PC via usbUSB, so I changed pins for communication with the ESP by SoftwareSerial to pins 10 and 11. Now it works. Thank you.
