Communicating/controlling hub from computer

[Jormono1]

Hello, I am working on a lego pen plotter. I have been trying to get it to run off an NXT, but I'm hitting a brick wall of not knowing NXC well enough (found a program but have had little luck getting to to work with my build, original build lacks too much detail or instruction to replicate) so I figured if I need to learn something Pybricks will be easier for me to learn (some minor foundation in python from a few years ago) and will be more useful of a skill to have vs learning NXC. I am however not seeing any way to solve a specific problem. The way I am envisioning this to work is on the hub is a simple program that receives instructions, mostly X,Y,Z coordinates and runs the motors to match the given coordinates. The data stream would ideally be coming from a computer, specifically I am thinking about using an old raspberry pi for this as I have some that aren't currently being used and they are small, power efficient, and I might setup some buttons and such via the GPIO to control the device. The problem I am seeing is that I can't figure out how to broadcast from a computer to the hub, the RPI has built-in bluetooth so I should be able to stream the data directly from the pi. I'm sure it is possible, as that is exactly how we upload the Pybricks OS and programs from a computer to the hub.

Disregard, I finally found this https://pybricks.com/projects/tutorials/wireless/hub-to-device/pc-communication/
