uni-app ble启动notify失败

测试过的手机：

华为pot-al00a 10.0.0.174
iPhone12.5.5

示例代码：

notifyBLECharacteristicValueChange() {  
    let deviceId = this.equipment[0].deviceId;  
    let serviceId = this.servicesData[0].uuid;  
    let characteristicId = this.characteristicsData[0].uuid;  
    let notify = this.characteristicsData[0].properties.notify;  
    console.log(deviceId);  
    console.log(serviceId);  
    console.log(characteristicId);  
    console.log(notify);  
    var that = this;  
    uni.notifyBLECharacteristicValueChange({  
        state: true, // 启用 notify 功能  
        // 这里的 deviceId 需要已经通过 createBLEConnection 与对应设备建立链接  
        deviceId,  
        // 这里的 serviceId 需要在 getBLEDeviceServices 接口中获取  
        serviceId,  
        // 这里的 characteristicId 需要在 getBLEDeviceCharacteristics 接口中获取  
        characteristicId,  
        success(res) {  
            console.log('notifyBLECharacteristicValueChange success:' + res.errMsg);  
            console.log(JSON.stringify(res));  
            that.onBLECharacteristicValueChange();  
        },  
        fail(res) {  
            console.log(JSON.stringify(res));  
        }  
    });  
},
