add_advertisment_status_changed error on Windows for example server

[Rhynorater]

The problem
When I run the server from the example, I get the below error:

PS C:\Users\Justin\Windows Scripts> python .\ble.py

My Solution :

Think to activate the Bluetooth on Windows :

And I suppose you need to be admin on your machine.
