纯血鸿蒙onBLECharacteristicValueChange不执行，不能监听，
notifyBLECharacteristicValueChange能写入，，
iOS和安卓可以全部正常
listenNotify(deviceId, serviceId, characteristicId) {
var _this = this;
// 1. 先销毁所有旧监听（鸿蒙必须）
wx.offBLECharacteristicValueChange();
// 2. 先注册监听！！！鸿蒙必须先注册，再开通知
wx.onBLECharacteristicValueChange((res) => {
console.log("✅鸿蒙收到数据:", res); // 这句一定要打印出来
_this.setData({
buletext: "设备连接中......",
});
});
wx.notifyBLECharacteristicValueChange({
state: true,
deviceId: deviceId.trim(),
serviceId: serviceId.trim(),
characteristicId: characteristicId.trim(), // 重点：用通知特征值ID，不是writeId！
type: 'notification', // 强制指定notification模式（解决鸿蒙默认走indication的问题）

你好麻烦提供请具体描述问题出现的流程，并提供能复现问题的简单代码片段（https://developers.weixin.qq.com/miniprogram/dev/devtools/minicode.html）。
console.log('特征值全量数据：', res.characteristics); 打印出来 notify是false , indicate是true, read是false , write是true
