UdpTransmitter is a simple tool to transmit simple udp packets over a network, or the internet.
All that requires is Ip address, port number and the message you want to send over UDP. I use this simple tool to simulate sensor udp traffic.
The software requires .net Framework 3.5 (Not included in the download), and should work straight out of the box on any Win 7, Server 2008 or newer.
