This is how I set the move type to be sent to web app in raspberry pi

CM_RandomEyesBroadcastEventTester.cs

using UnityEngine;
using System.Collections;

using CrazyMinnow.SALSA; // Import SALSA from the CrazyMinnow namespace

/*
	Script usage instructions

	This class demonstrates the use of the RandomEyes 2D/3D [Broadcast Eye Events], 
	and the RandomEyes 3D [Broadcast Custom Shape Events], to catch
	RandomEyes_OnLookStatusChanged and RandomEyes_OnCustomShapeChanged events.

	1. Create a GameObject and attach this script to it.
	2. Set this GameObject as a [Broadcast Receiver] in RandomEyes.
