wx.onBLECharacteristicValueChange一个页面能写两个监听吗?

 类似下面这种; 
// read  读取 监听返回数据
  startRead(characteristicId,serviceId,deviceId) {
    wx.onBLECharacteristicValueChange((res) => {console.log(res)})  // 监听蓝牙低功耗设备的特征值变化事件。
    wx.readBLECharacteristicValue({
      deviceId,
      serviceId,
      characteristicId,
    });
  },
// notify 监听返回数据
  startNotice(characteristicId,serviceId,deviceId) {
    wx.notifyBLECharacteristicValueChange({
      state: true,
      deviceId,
      serviceId,
      characteristicId,
      success: (res) => {
        wx.onBLECharacteristicValueChange((res) => {console.log(res)});// 监听蓝牙低功耗设备的特征值变化事件。
      },
    });
  },
