To send or receive a broadcast packet you need to put special options on the socket on the native side (setsockopt). You need to look if the SO_BROADCAST option is mentioned anywhere. If not it won’t work without adding them. And for sending them you need almost special privileges on the system. This is not a „user feature“.
