因此，我正在使用 Eclipse 開發(fā)一個 Java BLE Android 模塊（對模塊和 Appcelerator（制作 Android 應(yīng)用程序）進(jìn)行編碼）。我正在嘗試從 BLE 設(shè)備接收數(shù)據(jù)并將其顯示在 Android 手機(jī)上。我可以掃描設(shè)備并連接到它。但我真的，真的無法從它那里接收到任何數(shù)據(jù)。我已經(jīng)嘗試了至少 10 種不同的東西但是......主要問題是我不太了解 BLE API，而且我對 Java 有點菜鳥。誰能幫助可憐的人真正從設(shè)備中讀取數(shù)據(jù)？主要問題是設(shè)置藍(lán)牙特征 UUID（我有）。我只是不知道該怎么做...下面是模塊的代碼...public class AndroidbleModule extends KrollModule {      public static final String LCAT = "BLE";  private BluetoothManager btManager;  private BluetoothAdapter btAdapter;  private BluetoothDevice btDevice;  private TiApplication appContext;  private Activity activity;  private KrollFunction onFound;  private KrollFunction onConnections;  prvate BluetoothLeScanner btScanner;  private UUID uuid;  BluetoothGatt bluetoothGatt;  BluetoothGattCharacteristic btChar;  BluetoothGattCallbackHandler btData;  KrollDict kd;  Boolean isConnected = false;  BluetoothGatt connectedGatt;          private ScanCallback scanCallback = new ScanCallback() {  @Override  public void onScanResult(int callbackType, ScanResult result) {  BluetoothDevice device = result.getDevice();    if (device != null) {    BluetoothDeviceProxy btDeviceProxy = new   BluetoothDeviceProxy(device);    if (device.getName() != null) {      Log.d(LCAT, "Found: " + device.getName() + " " +   device.getAddress());      ArrayList<String> ids = new ArrayList<String>();        if (device.getUuids() != null) {             for (ParcelUuid id1 : device.getUuids()) {    ids.add(id1.toString());    }    }    btDevice = device;    kd = new KrollDict();    kd.put("name", btDevice.getName());    kd.put("macaddress", btDevice.getAddress());    fireEvent("nb_DevicesFound", kd);                          btScanner.stopScan(scanCallback);      }     }    }  };  我希望某個好心人會去天堂憐憫我，幫助我獲得那些甜蜜的數(shù)據(jù)字節(jié)。
