Hello, I am trying to develop a PC station. However, I am having a problem with getting it started. I am using
github.com/.../pc-ble-driver-py as a reference.
I was able to successfully install using pip install pc-ble-driver-py
However, when I am trying to run a example I get this error in the terminal.

I have a nrf52 development board connected with connectivity_115K2_2.0.1.hex installed
Am a missing a step?
Can somebody walk me through what I need to do?
I have visual studio installed on my computer.
