BlueSTSDK Python Bluetooth connection is_device_sleeping abstract method

[TNie.1]

I'm trying to connect to a sensortile.box via bluetooth with BlueSTSDK in python. When I want to get list of devices i got following error:

TypeError: Can't instantiate abstract class BlueSTAdvertisingData with abstract method is_device_sleeping

I got this error in all example files.

Examples from: https:

//github.com/STMicroelectronics/BlueSTSDK_Python.git

I was trying to change firmware, but with the same result. I can connect to sensortile.box with ST BLE Sensor on adnroid and everything works fine, but i need to use python for this purpose.
