Any help would be appreciated.

Hi Eti2704. Unfortunately I do not have a straight answer for you. This library was originally base don the flint project, and I took a lot of the information needed to build this from libpebble (https://github.com/Hexxeh/libpebble/). So PebbleSharp is certainly lacking some of the latest additions to the SDK.
With that said, to answer your question. If you connect your pebble with a PC and run the Demo WPF app you should see your app message come through. Start with a break point in ResponseManager.HandleResponse. If you still don't see the app message you expect move up to PebbleProtocol.ReadAndProcessBytes().
Once you know what the response should look like. You can register a callback to response to the message when it is received. See PebbleMediaViewModel for an example of how I did this to handle the music controls (though it is worth noting that in the latest firmware release something has changed so the messages are not getting though).

I suspect it will take some digging into PebbleKit (https://github.com/pebble/pebble-android-sdk/) to determine exactly what the message needs to look like. There are certainly updates and improvements that need to be made to the library but right now I have very limited free time to make the updates.
