vba Windows.Devices.Bluetooth

回答: 在VBA中，可以使用Windows.Devices.Bluetooth命名空间来进行蓝牙操作。首先，你需要创建一个BluetoothLECode对象，并传入服务GUID、写特征GUID和通知特征GUID。然后，你可以订阅ValueChanged事件来处理蓝牙设备的值变化。具体的调用方式如下所示:

bluetooth = new BluetoothLECode(_serviceGuid, _writeCharacteristicGuid, _notifyCharacteristicGuid);
bluetooth.ValueChanged += Bluetooth_ValueChanged;

在Windows系统中，你可以通过以下方式获取默认蓝牙适配器的路径:

export BTADAPTER=`dbus-send --system --dest=org.bluez --print-reply / org.bluez.Manager.DefaultAdapter | tail -1 | sed 's/^.*"\(.*\)".*$/\1/'`

希望这些信息对你有帮助。
