Android BLE扫描结果和扫描记录

Question

我正在尝试获取扫描结果，服务数据，UUID和设备名称，但找不到。这些值将为空。

设置过滤器时，不会调用扫描回调。在扫描过滤器代码下方

 ArrayList<ScanFilter> filters = new ArrayList<ScanFilter>();
                 ScanFilter filter = new ScanFilter.Builder()
                .setServiceUuid(new ParcelUuid(UUID.fromString("UUID")))
                .build();
        filters.add(filter);

        ScanSettings.Builder settings = new ScanSettings.Builder()
                .setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY);
   btScanner.startScan(filters,settings,scanCallback);

请帮助我............ 谢谢
