the part of inittwin in ble mapper

[1180300515]

now i have a ble device , the twin propertyName is on-off , as it's name ,it control the sensor on-off ,the question is that it's property is write,so i can't read it's value ,but the twin has the desire and report value,so how can i get the report value?
in the code about the func inittwin ,after the func setVisitor finish,it begin to judge whether the property is notify or read ,and then send the report value.but the property is write ,so i can't get the report value.
the code is from device.go

if (c.Property&ble.CharNotify) != 0 && c.CCCD != nil {
	wg.Add(1)
	go func() {
		if err := twinData.BleClient.Client.Subscribe(c, false, twinData.notificationHandler()); err != nil {
			klog.Errorf("Subscribe error: %v", err)
			wg.Done()
		}
	}()
} else if (c.Property & ble.CharRead) != 0 { // // read data actively
        timer := mappercommon.Timer{Function: twinData.Run, Duration: collectCycle, Times: 0}
	wg.Add(1)
	go func() {
		defer wg.Done()
		timer.Start()
	}()
}
