在跨平台Windows/Android Kivy应用程序中使用BLE？

Question

我正在使用Kivy开发一个跨平台的应用程序（适用于Windows和Android目标），我需要使用蓝牙低能耗（与ESP32 BLE服务器通信）。我尝试使用Bleak来处理不稳定的连接，但导入Bleak模块使我的应用程序崩溃。我使用threading.Thread来分割BLE和Kivy应用程序，但我仍然有一个问题，因为我必须在我的主python文件中导入Kivy和Bleak模块

我的主应用程序：

# coding: UTF-8
#!/usr/bin/python3
import threading
import asyncio
import time
from queue import Queue
from interface_kivy import MainApp # Python file with the Kivy import
from ble_kivy import ble_kivy_interface # Python file with the Bleak import

async def main():
    kivy_thread = threading.Thread(group=None, target=MainApp().run(), name='Service kivy IHM')
    kivy_thread.daemon = True
    kivy_thread.start()
    
    my_queue = MainApp().getIHMqueue()
    print(f"{my_queue}")
    kivy_thread.join()
        

loop = asyncio.get_event_loop()
loop.run_until_complete(main())

当from ble_kivy import ble_kivy_interface被注释时的输出：

我在这里和那里看到（问题476，176，6816）人们面临着类似的问题，但这些github问题是一年前提出的，我相信事情可能已经发生了变化

有办法解决吗？如果没有，是否有一个既适用于Win又适用于Android的替代方案，或者我必须使用不同的框架
