Ionic and Arduino Communication (Bluetooth)

Hello All! I’m new to Ionic app development and had a few question on how to get started, or moreso how to get my app and my Arduino trading information. I am trying to make a simple app to be able to change the color of a light on a adafruit ring light connected to the Arduino. Problem is, I have be unsuccessful in being able to get them to speak.

Because I want to make this app as simple as possible, I have followed the PhoneGap tutorial for light changes as far as actually changing color and sending data to the Arduino is concered, but have been unable to get any reliable feedback to the Arduino, or any feedback whatsoever. this is especially concerning, since I have the bluetooths connected using a different app, but still connected nonetheless.

Anybody out there can help? I’d much appreciate some advice.
