UDP broadcast

[RookieCLY]

Could I use udp-broadcast like Fast-DDS instead of giving a certain ip address？
For example, in the PublishHelloWorldExample, I need to start with command "./PublishHelloWorldClient 192.168.1.100 7410". If I want to start without giving the ip "192.168.1.100", but I need the client (in the board, with ip 192.168.1.xxx) connect to the agent (in the pc, with ip 192.168.1.xxx) , what should I do with configuration?
