UDP is a simple application whose purpose is to send UDP packets using UDP (User Datagram Protocol), a fast and low latency sending protocol. You can send these packets through the WiFi network, defining an IP address, a port and an interface that allows you to configure the packets to be sent. You can use this app to send simple and fast commands to other connected devices on your network. You can control things like: - Simple robots based on Arduino - Desktop/mobile applications that listen for commands with the UDP protocol - Any DIY ideas you can think of This application is free and does not display any type of advertising.
