我正在开发一个简单的应用程序来扫描BLE设备，并过滤扫描结果以仅查找我的ESP32。我希望通过过滤服务UUID来查找我的ESP32。我已确认广告数据中存在我的自定义服务（通过nRF Connect在“128位服务UUID的完整列表”中列出服务）然而，当我在扫描之前将服务UUID过滤器添加为ScanFilter时，我的ScanCallback从来没有被调用过。但是我可以删除扫描过滤器，并手动检查服务是否存在于ScanCallback中。请参见下面的代码示例。
第一个示例使用手动过滤，效果很好。

private ParcelUuid mServiceUuidFilter = ParcelUuid.fromString("6E400001-B5A3-F393-E0A9-E50E24DCCA9E");

    private final ScanCallback mScanCallback = new ScanCallback() {
        @Override
        public void onScanResult(int callbackType, ScanResult result) {
            boolean matched = (mServiceUuidFilter == null);
            if (mServiceUuidFilter != null && result.getScanRecord().getServiceUuids() != null) {
                for (ParcelUuid uuid : result.getScanRecord().getServiceUuids()) {
                    if (uuid.equals(mServiceUuidFilter)) {
                        matched = true;
                        break;
                    }
                }
            }

            if (matched) {
                // do something
            }
        }
    };
    
private void scan() {
        List<ScanFilter> scanFilters = new ArrayList<>();
        // works
        ScanFilter filter = new ScanFilter.Builder().build();
        scanFilters.add(filter);
        ScanSettings scanSettings = new ScanSettings.Builder().build();

        // skipping mScanner initialization
        mScanner.startScan(scanFilters, scanSettings, mScanCallback);
}

第二个示例使用ScanFilter进行筛选，但不起作用。mScanCallback从未被调用。

private ParcelUuid mServiceUuidFilter = ParcelUuid.fromString("6E400001-B5A3-F393-E0A9-E50E24DCCA9E");

    private final ScanCallback mScanCallback = new ScanCallback() {
        @Override
        public void onScanResult(int callbackType, ScanResult result) {
            // do something
        }
    };
    
private void scan() {
        List<ScanFilter> scanFilters = new ArrayList<>();
        // does not work
        ScanFilter filter = new ScanFilter.Builder().setServiceUuid(mServiceUuidFilter).build();
        scanFilters.add(filter);
        ScanSettings scanSettings = new ScanSettings.Builder().build();

        // skipping mScanner initialization
        mScanner.startScan(scanFilters, scanSettings, mScanCallback);
}

我是不是漏掉了什么？
