UDP multicast connection.

[jenya7]

I connect to a common AP with several ESP modules. Or alternatively I configure a softAP on one and connect to it with others.
Then I shoul create a connection
AT+CIPSTART="UDP","172.161.1.128",8000,1112,2 - if AT+CIPMUX=0
AT+CIPSTART=4,"UDP","172.16.1.154",8000,1112,0 - if AT+CIPMUX=1
But what if I want to send broadcast messages - anyone can send to anyone and receive from anyone.
How can I do it?

Try "172.161.1.255"
