react-native - 从 BLE 血糖仪 React Native 中检索血糖数据

Question

我正在使用React-Native-Ble-Manager从血糖仪（Accu-Check Guide）中检索数据。我是蓝牙新手。我可以收听记录访问控制点的通知，该通知提供：-

[6,0,48,4]

但我不知道下一步该怎么做才能得到所有的葡萄糖测量值。我的代码如下。

BleManager.connect(selectedDevice.id).then((peripheral) => {
  BleManager.retrieveServices(selectedDevice.id).then((servicesInfo) => {
    BleManager.startNotification(
      selectedDevice.id,
      "00001808-0000-1000-8000-00805f9b34fb",
      "00002a18-0000-1000-8000-00805f9b34fb"
    )
      .then(() => {
        BleManager.startNotification(
          selectedDevice.id,
          "00001808-0000-1000-8000-00805f9b34fb",
          "00002a52-0000-1000-8000-00805f9b34fb"
        ).then((result) => {
          NativeAppEventEmitter.addListener('BleManagerDidUpdateValueForCharacteristic', function (data) {
            console.log('RESULT FROM RAPC NOTIFICATION')
            console.log(data) //[6,0,48,4]
          });
        });
        var myData = "0x0101";
        const payloadBytes = stringToBytes(myData);
        BleManager.write(
          selectedDevice.id,
          "00001808-0000-1000-8000-00805f9b34fb",
          "00002a52-0000-1000-8000-00805f9b34fb",
          payloadBytes
        )
          .then(() => {
            console.log("success");
          })
          .catch((error) => {
            console.log(error);
          });

        return;
      })
      .catch((error) => {
        // Failure code
        console.log(error);
      });
  });
});

提前致谢。
