Windows User must have a "[Bluegiga BLED112 Bluetooth Smart Dongle]"?
I'm already use Scratch 3.0 with Lego boost.

To check the connection possibility, you can just use
import logging
import time
from pylgbst import get_connection_auto
logging.basicConfig(level=logging.DEBUG)
conn = get_connection_auto()
conn.enable_notifications()
time.sleep(60) # wait 1 minute to gather infoThat would give some more debugging information, might help understanding what does not work.
The requirement for BLED112 requirement is written for "the Windows version of pygatt".
On Windows, different types of BLE hardware and different versions of libraries are known to have problems. It requires some experimentation and troubleshooting sometimes. I don't have any better solution for now.

Refer to https://github.com/rphuang/IotDevicesPy
There is the explanation with Install at windows
It works. & I try to check deeply for my thinking.
Anyway, Robot moving.
I will compare your code.
Thanks
Best Regards

Tried to do this:
`from pylgbst.hub import MoveHub
from pylgbst import get_connection_bleak
conn = get_connection_bleak(hub_name='Move Hub')
hub = MoveHub(conn)
for device in hub.peripherals:
print(device)`
The connection looks to established (blue constant LED on MoveHub), but MoveHub very quickly switched off.
