Hi!

Is there a sample of how to use the SendAndWaitForResponse or the SendAndWaitForValidResponse methods of Connection Class?
We using the Zebra.Printer.SDK 2.15.2634, for C# Xamarin.Forms;
We need to understanding how to get the response.
In my tests, in some situations (HeadOpen), always returns byte[0] and i doesn't understand how to pass the ResponseValidator to get a valid response.
I've searching into the web for samples, but found only the official documentation of zebra with no samples.
Thanks!

Here are the examples of using SendAndWaitForResponse with or without a validator.

// Send SGD and wait for the response until timeouts.
byte[] response = connection.SendAndWaitForResponse(GetBytes("! U1 getvar \"ezpl.label_length_max\"\r\n"), 300, 200);

// Send host status command (~HS) and wait for the response until timeouts or until NULL character.
byte[] data = connection.SendAndWaitForResponse(GetBytes("~HS"), 3000, 3000, "\0");
