App development for a golf simulator

Curious if anyone has any experience, very niche topic, I know.

A golf simulator is a device with a bunch of sensors/cameras that you point at the golf ball, when you hit it all those sensors read tons of different data points on the club and ball. That’s the hardware.

The software, there are many different options but they all run on an external device. The one I’m familiar with runs on an iPad, and you link the simulator device to the iPad through Bluetooth, and you swing and hit the ball into a net and the software takes the data and creates/estimates the flight of the ball.

1. How could I look into the data being sent from the hardware?

2. There are two separate apps on the iPad that do the same thing, they aren’t connected or affiliated. That must mean they’re both taking raw data from the device, calculating it and then representing it with a ball flying, right?

I’m trying to figure out how it all works.

Thanks
