I'm trying to set esp8266 as udp server on Arduino. I interaсt between Arduino and Esp8266 through AT commands. I know that for starting esp8266 as TCP-server I can use command AT+CIPSERVER=<type>,<port>. But how to start esp8266 as UDP-server or udp listener on socket through AT commands? I need it for receiving multicast messages.

Can't help you with UDP Multicast on the AT firmware, but for the ESP8266-Arduino environment I have a working UDP Multicast Server example over here:
