安卓和ios在wx.notifyBLECharacteristicValueChange成功之后调用wx.onBLECharacteristicValueChange没有回调,具体代码请见代码片段链接，谢谢！

help，wx.onBLECharacteristicValueChange 在android上无法接受返回值，notify开启是成功的，有趣的是在iOS下面一切正常，问了好多人，又说开启notify之后立即就调用了write会发生问题，尝试了延迟和重发依旧没有任何返回值，下图是测试返回的结果 ···························································································································· [图片] 上图是在ios设备的截图，能接收到返回值 ·································································································· [图片] 这实在android设备的，没有返回值 ··································································································· - 求问技术支持，这问题该如何解决，是否有解决方案，下面贴出我的代码，帮忙看看是不是我写的有问题 [代码]Page({[代码] [代码]  [代码][代码]/** 页面的初始数据 */[代码][代码]  [代码][代码]data: {[代码][代码]    [代码][代码]deviceId: [代码][代码]'FD:76:74:35:99:92'[代码][代码],[代码][代码]    [代码][代码]serviceId: [代码][代码]''[代码][代码],[代码][代码]    [代码][代码]services: [],[代码][代码]    [代码][代码]writeCharacteristicsId: [代码][代码]""[代码][代码],  [代码][代码]// 可写特征值uuid[代码][代码]    [代码][代码]readCharacteristicsId: [代码][代码]""[代码][代码],   [代码][代码]// 可读特征值uuid[代码][代码]    [代码][代码]notifyCharacteristicsId: [代码][代码]""[代码][代码], [代码][代码]// 通知特征值uuid[代码][代码]  [代码][代码]},[代码] [代码]  [代码][代码]/** 生命周期函数--监听页面加载 */[代码][代码]  [代码][代码]onLoad: [代码][代码]function[代码] [代码](opt) {[代码][代码]    [代码][代码]//初始化蓝牙适配器[代码][代码]    [代码][代码]wx.openBluetoothAdapter({[代码][代码]      [代码][代码]success: [代码][代码]function[代码] [代码](res) {[代码][代码]        [代码][代码]console.log([代码][代码]"初始化蓝牙适配器成功"[代码][代码], res);[代码][代码]      [代码][代码]},[代码][代码]      [代码][代码]fail: [代码][代码]function[代码] [代码](err) {[代码][代码]        [代码][代码]console.log([代码][代码]"初始化失败"[代码][代码], err)[代码][代码]      [代码][代码]}[代码][代码]    [代码][代码]})[代码] [代码]    [代码][代码]//监听蓝牙适配器状态变化事件[代码][代码]    [代码][代码]wx.onBluetoothAdapterStateChange(res => {[代码][代码]      [代码][代码]console.log([代码][代码]"状态变化"[代码][代码], res)[代码][代码]    [代码][代码]})[代码][代码]  [代码][代码]},[代码] [代码]  [代码][代码]start: [代码][代码]function[代码][代码]() {[代码][代码]    [代码][代码]let that = [代码][代码]this[代码][代码];[代码] [代码]    [代码][代码]console.log([代码][代码]'监听设备的连接状态'[代码][代码]);[代码] [代码]    [代码][代码]/** 连接设备 */[代码][代码]    [代码][代码]wx.createBLEConnection({[代码][代码]      [代码][代码]deviceId: that.data.deviceId,[代码][代码]      [代码][代码]success: [代码][代码]function[代码] [代码](res) {[代码][代码]        [代码][代码]console.log([代码][代码]'连接设备'[代码][代码], res);[代码] [代码]        [代码][代码]/** 监听设备的连接状态 */[代码][代码]        [代码][代码]wx.onBLEConnectionStateChanged([代码][代码]function[代码] [代码](res) {[代码][代码]          [代码][代码]console.log(`device ${res.deviceId} state has changed, connected: ${res.connected}`)[代码][代码]        [代码][代码]});[代码] [代码]        [代码][代码]/** 连接成功，后开始获取设备的服务列表 */[代码][代码]        [代码][代码]wx.getBLEDeviceServices({[代码][代码]          [代码][代码]deviceId: that.data.deviceId,[代码][代码]          [代码][代码]success: [代码][代码]function[代码] [代码](res) {[代码][代码]            [代码][代码]console.log([代码][代码]'device services:'[代码][代码], res);[代码] [代码]            [代码][代码]that.setData({ services: res.services, serviceId: res.services[0].uuid }, () => {[代码] [代码]              [代码][代码]wx.getBLEDeviceCharacteristics({[代码][代码]                [代码][代码]deviceId: that.data.deviceId,[代码][代码]                [代码][代码]serviceId: that.data.serviceId,[代码][代码]                [代码][代码]success: [代码][代码]function[代码] [代码](res) {[代码][代码]                  [代码][代码]console.log([代码][代码]'device getBLEDeviceCharacteristics:'[代码][代码], res.characteristics);[代码] [代码]                  [代码][代码]for[代码] [代码]([代码][代码]var[代码] [代码]i = 0;

我连接的是一个蓝牙体温计，在调用wx.notifyBLECharacteristicValueChange订阅成功后，调用 wx.onBLECharacteristicValueChange监听特征值变化，之后测量体温成功后无法收到回调，所有具有notify的特征值我都试过了，都不行。这是什么原因呢，有什么结局方案？ [图片]
