Every message from the device app to the companion app loses all data.

[ciaranoh]

Even using the simple weather app sample, every message iI send via messaging.peerSocket.send from the device app gets received as {"isTrusted":false} with no other data.  The message is received, just without any of the data I added.  I'm using a simulator for both the device and companion app.  Is this just not supported?

Can you provide some code? Or perhaps start with the sample here:

I was bashing my head against the wall with exactly the same problem for some time. In my case the problem was that I failed to notice that the message is actually in the `data` member of the event object you get. This `data` itself is not an 'own' property of the event, ie it's inherited from a class definition or so, so it does not show up when JSON.stringifying() the event.

@triggi I was having the same issue and your suggestion solved it, thanks.
