Elaborate.

Try it on the simulator/on the real thing.

Your error says only it can't connect to a device.

Does any app load to a (simulated) device?

I connect to my iPhone and my watch, how can i catch message from my iPhone😥

I assume you have developer mode on on both phone and fitbit.

Why are you not using a simulator? 

[Sammmmmi]

I using simulator before and it work.But I need to output these data to database.So i want to try some physical thing

The Fitbit messaging API only sends messages between the clockface/app running on the watch, and the companion component of that clockface/app which runs within the Fitbit mobile app on your phone. To get messages out of the Fitbit system, you have to use fetch() or WebSocket within your companion component.

The RPC error is not related to the messaging API. It just indicates that your phone or simulator isn't connected to the development environment.
