The Microchip TCP/IP Discoverer PC project (fomerly known as the Embedded Ethernet Device Discoverer) will aid in embedded product device discovery (with the Announce protocol) and will demonstrate how to write PC applications to communicate to embedded devices.
When the "Discover Devices" button is clicked, this application will transmit a broadcast UDP packet containing the message, "Discovery: Who is out there?" on the local network to port 30303. If any embedded devices with the Announce protocol enabled are connected to the network, they will respond with a UDP packet containing their host name (NBNS) and MAC address.
The Java source code for this application is also included. This source code should provide a rough idea of how to write a PC-based application to communicate with your embedded devices.
