Local Device Finder

日本語 | English

Local Device Finder is a C# library for detecting devices on a local network. It sends discovery messages using UDP broadcast and multicast, then waits for responses from the devices.

Features

• Detect devices on the local network.
• Works in both Editor and Runtime modes.
• If ports are set up properly, it is possible to test both sending and receiving on a single PC.
• Responses are customizable. In the sample, only the device name is returned as a response, but you can add any information to the response.
• Supports both UDP broadcast and multicast, with multicast reducing network load.
• It is possible to send data individually to detected devices.
