    Hello,

    I have a question; I am busy building an app for PDA (Scanner/terminal) devices. There is only one problem. They use a broadcast to receive some input.

    But how can I receive the broadcast value from the Android PDA in Unity?

    Kind regards,

    Seb

    Hello @sebhah. If I understand your question you want to write some c# code to receive UDP datagrams from anywhere on your subnet. It's pretty easy to do using System.Net and System.Net.Sockets. You will need to figure out your subnet and the port the sender is sending to. Once you have that information you can instantiate a UdpClient and IPEndPoint. Then call receive from the client on the end point inside a loop until you are ready to shutdown your client. Here is an example UDPListener that should do what you want.

    If I understand the problem correctly, you need an Android broadcast receiver and forward the data from received intent to Unity code?
    If so, the receiver would have to implemented in Java. For calling C# code from Java, have a look at AndroidJavaProxy in our scripting api documentation.
