plus.bluetooth.readBLECharacteristicValue报错: {"code":10007,"message":"property not support"}

使用plus.bluetooth.readBLECharacteristicValue时，报错: {"code":10007,"message":"property not support"}

我再原生测试了特征值都正常获取到数据，但在H5+就报错了，在H5+能够启动notify功能，但使用readBLECharacteristicValue就报错{"code":10007,"message":"property not support"}，根本不知道问题出在哪？
下面是我的代码：
// 启用低功耗蓝牙设备特征值变化时的notify功能
function startCharacteristicsNotify(deviceId){
var serviceId=$("#serviceList").val();
var characteristicId=$("#characteristicList").val();
// 监听低功耗蓝牙设备的特征值变化
plus.bluetooth.onBLECharacteristicValueChange(function(e){
if(characteristicId == e.characteristicId){
var value =JSON.stringify(e.value);//这里返回的value也是空的“{}”

            // 读取低功耗蓝牙设备的特征值  
        plus.bluetooth.readBLECharacteristicValue({  
            deviceId:deviceId,  
            serviceId:serviceId,  
            characteristicId:characteristicId,  
            success:function(e){  
                mui.hideLoading();  
                console.log('read characteristics success: '+JSON.stringify(e));  
                $("#textarea").val(JSON.stringify(e));  
            },  
            fail:function(e){  
                mui.hideLoading();  
                console.log('read characteristics failed: '+JSON.stringify(e));  
                $("#textarea").val(JSON.stringify(e));  
            }  
        });  
    }  
});  
// 启用notify功能  
plus.bluetooth.notifyBLECharacteristicValueChange({  
    deviceId:deviceId,  
    serviceId:serviceId,  
    characteristicId:characteristicId,  
    success:function(e){  
        var characteristics = e.characteristics;  
        console.log(JSON.stringify(characteristics));  
        $("#textnotify").val(JSON.stringify(e));  
        if(characteristics!=undefined){  
            //console.log('get characteristics success: '+characteristics.length);  
            for(var i in characteristics){  
                console.log(i+': '+JSON.stringify(characteristics[i]));  
            }  
        }  
    },  
    fail:function(e){  
        console.log('get characteristics failed: '+JSON.stringify(e));  
        $("#textnotify").val(JSON.stringify(e));  
    }  
});  

}

能够正常启动notify功能，在读取低功耗蓝牙设备的特征值的时候就报错了： {"code":10007,"message":"property not support"}
