蓝牙低功耗扫描立即失败

Question

我正在尝试构建一个使用BLE的应用。我在运行Android 5.0.1的三星Galaxy S5上测试这个应用程序。当我尝试扫描蓝牙设备时，我立即在日志中找到它：

03-25 17:39:41.235 2696-2714/com.example.multiplayertest D/BluetoothLeScanner: onClientRegistered() - status=0 clientIf=7
03-25 17:39:41.245 2696-2696/com.example.multiplayertest I/System.out: -99
03-25 17:39:41.245 2696-2696/com.example.multiplayertest I/System.out: failed

扫描失败，错误代码为-99。我无法找到这意味着什么，你可以给予任何帮助。

扫描码：

    final BluetoothLeScanner scanner = bluetoothAdapter.getBluetoothLeScanner();
    final ArrayList<ScanFilter> filterList = new ArrayList<>();

    ScanFilter.Builder scanBuilder = new ScanFilter.Builder();
    scanBuilder.setServiceUuid(new ParcelUuid(serviceUuid));
    filterList.add(scanBuilder.build());

    ScanSettings.Builder settingsBuilder = new ScanSettings.Builder();
    settingsBuilder.setScanMode(ScanSettings.SCAN_MODE_BALANCED);

    scanner.startScan(filterList, settingsBuilder.build(), scanCallback);

和scanCallback：

ScanCallback scanCallback = new ScanCallback() {
    @Override
    public void onScanResult(int callbackType, ScanResult result) {
        super.onScanResult(callbackType, result);
        System.out.println("Result");
    }

    @Override
    public void onBatchScanResults(List<ScanResult> results) {
        super.onBatchScanResults(results);
        System.out.println("Results");

    }

    @Override
    public void onScanFailed(int errorCode) {
        super.onScanFailed(errorCode);
        System.out.println(errorCode);
        System.out.println("failed");

    }
};
