UNO+WiFi R3 ATmega328P+ESP8266 Wifi AT command problem

hello. I use robotdyn uno+wofi r3 board, rs232 shield and lcd screen. I use rx/tx 10-11 for rs shield and it works ok. I checked esp8266 chipset with at commands via computer and they work ok. but I couldn't figure out how to communicate between atmega and esp chipset together. I configure the jumper switches to MCU+ESP mode.I would like to send AT commands to esp and print the response to lcd screen. I assume it uses software serial but which rx/tx pins should I use? manual says there is no need to wire esp to atmega. what is the logic between them? Can anybody paste sample code here? thanks.

I read this thread many times but I couldn't understand it. And most of the comments made based on mega board which has serial3 communication but I use uno which doesn't have. and without json simply at commands what I need to do.

there is no connection for SoftwareSerial to esp8266 in Uno+WiFi. you can patch one with jumper wires to the esp8266 header, but you can't use two SoftwareSerial instances to listen at the same time

yes, thank you. you are right. I thought arduino communicates with esp via software serial pins but it turned out that after configuring jumper settings to mcu+esp it communicates via direct serial like you connect it to pc usb.
