这是我的 LED 和蜂鸣器通知代码
Symbol.Generic.Device device = new Symbol.Generic.Device();
Symbol.Notification.Beeper sound = new Symbol.Notification.Beeper(device);
sound.Volume = 5;
sound.Frequency = 300;
Symbol.Notification.LED led = new Symbol.Notification.LED(device);
led.CycleCount = 5;
led.OffDuration = 2000;
led.OnDuration = 3000;
但我看不到任何通知 =/
