关于#微信小程序#的问题：上述就是我写的关于开启notify的代码，我在哪里接收来自蓝牙的notify数据呢？

我在代码层准备开启蓝牙notify功能

wx.getBLEDeviceCharacteristics({
      deviceId,
      serviceId,
      success: (res) => {
        console.log('检查是否有写入,读取权限', res.characteristics)
        for (let i = 0; i < res.characteristics.length; i++) {
          let item = res.characteristics[i]
          if (item.properties.notify || item.properties.indicate) {
            console.log('可以开启通知',deviceId,serviceId,item.uuid)
            wx.notifyBLECharacteristicValueChange({
              state: true,
              deviceId,
              serviceId,
              characteristicId: item.uuid,
              success(res) {
                console.log('notifyBLECharacteristicValueChange 成功', res)
              }
            })
          }
          if (item.properties.read) {
            wx.readBLECharacteristicValue({
              deviceId,
              serviceId,
              characteristicId: item.uuid,
            })
          }
          if (item.properties.write) {
            this.setData({
              canWrite: true
            })
            this._deviceId = deviceId
            this._serviceId = serviceId
            this._characteristicId = item.uuid
            this.writeBLECharacteristicValue()
          }

        }
      },
      fail(res) {
        console.error('getBLEDeviceCharacteristics', res)
      }
    })

上述就是我写的关于开启notify的代码，现在想请问，我在哪里接收来自蓝牙的notify数据呢？
