Receiving Multicast

I try to receive multicast with ESP8266 using At commands.
I am using this commands to initalize an UDP socket.


There are protocols on port 9522 and multicast adress
I can receive the protocols on my laptop (connected to the same AP) but there is nothing on my ESP8266

I found another code sequence (is from ESP32)

AT+MDNS=1,1,"sma","iot",9522 (-> here it is =1,1 ?? not working on ESP8266)
AT+MDNS=0,1 (-> here it is =0,1 ?? not working on ESP8266)

When using this code (with modified syntax for AT+MDNS) my conection to the AP seems to be gone (BSSID is 0 and IP is 0)

Has anyone an idea what I do wrong?
Is multicast working on ESP8266 at all?

Thank you for any help

Which version are you using? Maybe you can have a try with the latest AT?
