UDP will be hearing in port 49161 so you can send short instructions from Orca or any other program you desire. This project is mainly headed to receive short UDP commands from ORCΛ but on develop branch also UDPX Pixel library coded by IoTPanic is included. So if the UDP payload is major than 9 pixels it will trigger the binary protocol. To test it there is an online tool called UDPX. As a prerequisite you need to start from this repository a script to act as a middleware:
nodejs middleware.js
