LEAP MOTION - dynamically changing tracking orientation C#

Hi,

I'm working on a project where hands are tracked from both sides of the device (only one side at a time). I'm having trouble with accessing the config settings to reverse the orientation from a C# script.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using Leap.Unity;
5. using Leap;
6.  
7. public class LeapConfigTester : MonoBehaviour {
8.  
9.     public LeapServiceProvider leapProvider;
10.     public Controller leapController;
11.     public Config leapConfig;
12.  
13.     void Start()
14.     {
15.         leapController = leapProvider.GetLeapController();
16.         leapConfig = leapController.Config;
17.     }
18.  
19.     void Update () {
20.         if (Input.GetKeyDown(KeyCode.Space))
21.         {
22.             bool isFlipped = leapConfig.GetBool("image_processing_flipped");
23.             Debug.Log("Currently flipped: " + isFlipped);
24.  
25.             bool setSuccess = leapConfig.SetBool("image_processing_flipped", !isFlipped);
26.             Debug.Log("Set success: " + setSuccess);
27.  
28.             bool saveSuccess = leapConfig.Save();
29.             Debug.Log("Save success: " + saveSuccess);
30.  
31.             bool connectedController = leapController.IsConnected;
32.             Debug.Log("Controller connected: " + connectedController);
33.         }
34.     }
35. }
36.  

This prints to the console:

Code (csharp):

1. Currently flipped: True
2. Set success: True
3. Save success: False
4. Controller connected: True

I'm essentially trying to make the spacebar function like the "Reverse Orientation" button in the Leap Control Panel.
Any idea why the save method is failing?

Thanks,
Mungo
