蓝牙设备断开连接时出现PyBluez事件

如何解决蓝牙设备断开连接时出现PyBluez事件

目前我正在使用PyBluez检查是否连接了特定的蓝牙设备

import threading
import bluetooth

known_devices_mac = ["FF:A0:AB:21:20:F4"]

def finder():
    while True:
        for mac in known_devices_mac: #1 second per device :( (if I add more devices  time increases exponentially so that needs to be fixed as well :) (maybe every device would have a separate thread?? expecting around 20devices)
            #Try to connect to device and if you can return some info
            #10 seconds if device not in range
            #1 second if device is  in range
            name = bluetooth.lookup_name(mac,timeout=1)
            services = bluetooth.find_service(address=mac)

            if name == None and services == []:
                print("{0} not in range".format(mac))
                CallAPINotInRange(mac)
            else:
                temp_mac = "nope"
                try:
                    temp_mac = services[0]["host"]
                except:
                    temp_mac = "nope"
                if (temp_mac == mac): #sometimes services aren't defined ye>
                    print("{0} in range\n\tName: {1}\n\n".format(mac,name))
                    CallApiInRange(temp_mac)
def main():

    #Bluetooth scanner thread
    thread = threading.Thread(target=finder,name="finder")
    thread.start()

if __name__ == "__main__":
    main()

在配对模式下，我会获得设备的蓝牙地址（因为我发现（至少在我的Samsung Galaxy S10 +上）它不会更改

问题是我的API使用限制为每秒20个请求，每小时1500个请求，每天10000个请求，因此如果我每秒请求一次，我当然会很快达到上限（因为它要求设备是否存在，并且每秒检查设备是否存在

任何人都不知道我该如何创建一个事件或类似的事情，当设备实际上不在范围内时会触发该事件，这样我就可以减少调用我的API的次数

感谢纠缠和问候！
