UDP multicast dynamic group and port

[davidz]

For the UDP out node, the destination ip and port number can be set up dynamically in UDP message and broadcast message.

Is it possible to set up the group and port dynamically in multicast message? If the fields are left blank in multicast, Node-RED gives an error.

Not currently no, as the node creates and binds the socket at deploy time and re-uses it for each message. It would need to be re-written to re-create the socket on each call.

Thanks Dave!
