Divide your project into parts. To get the interface to the Flyport (whatever that is) working, write a test sketch that just sends a hard-coded message and get that interface working before you then try to use it in the rest of your project. I suggest you also test the VR part in isolation if you haven't already done it. Once both these interfaces work, all you need to do is include both features in a sketch that receives the input text from the VR interface and sends it to the Flyport interface.
