Hi,  
I'm fairly new to using Node-red. I'm using a software that sends commands to external hardware (a sphero ball) through an IP address (127.0.0.1) and a port number(1000) (photo below). I was wondering if there's a way to read and retrieve this information in node-red?

did you search the flow library to see if there is a node you could use?

i figured i could use a "udp in" node to read the information on that ip address and port number.
