【问题描述】：
我已经没有关于如何调试这个的想法......我正在尝试在 Python 中实现蓝牙低功耗外设，并不断收到此错误：
dasbus.error.DBusError: No valid service object found
这是sudo dbus-monitor --system "destination='org.bluez'" "sender='org.bluez'" 上发生的事情

/var/log/syslog 提供一点线索：
bluetoothd[22894]: Failed to read "UUID" property of service
bluetoothd[22894]: Failed to add service
bluetoothd[22894]: Failed to create GATT service entry in local database
依赖项设置起来很麻烦，所以这里有一个 docker 容器：
docker run -it --rm \
--privileged \
--workdir /app \
--volume "$PWD":/app \
--volume /var/run/dbus/:/var/run/dbus/:z \
soodesune/python3-bluetooth dbus-bluetooth.py
我还能做些什么来调试这个错误？如何找出我的 Service UUID 有什么问题？
