ble_read_state.py doesn't find any devices

[mainmaster]

Am I doing something wrong, or has the protocol changed and the script doesn't work? Could you confirm or deny?
Is the bluetooth adapter built into the laptop suitable?
Thank you

Is the bluetooth adapter built into the laptop suitable?

Depends on which one it is. The Panda Bluetooth 4.0 USB adapter worked for me when I tested it in 2020
