如何设置BLE扫描间隔和窗口只是在android中选择模式？

Question

我是android的新手。我想在我的Android设备中设置BLE扫描间隔和窗口，以便进行有关邻居发现的实验。我在谷歌搜索答案，并知道android's source code中有关于BLE扫描间隔和窗口的定义如下

/**
 * Scan params corresponding to regular scan setting
 */
private static final int SCAN_MODE_LOW_POWER_WINDOW_MS = 500;
private static final int SCAN_MODE_LOW_POWER_INTERVAL_MS = 5000;
private static final int SCAN_MODE_BALANCED_WINDOW_MS = 2000;
private static final int SCAN_MODE_BALANCED_INTERVAL_MS = 5000;
private static final int SCAN_MODE_LOW_LATENCY_WINDOW_MS = 5000;
private static final int SCAN_MODE_LOW_LATENCY_INTERVAL_MS = 5000;

/**
 * Scan params corresponding to batch scan setting
 */
private static final int SCAN_MODE_BATCH_LOW_POWER_WINDOW_MS = 1500;
private static final int SCAN_MODE_BATCH_LOW_POWER_INTERVAL_MS = 150000;
private static final int SCAN_MODE_BATCH_BALANCED_WINDOW_MS = 1500;
private static final int SCAN_MODE_BATCH_BALANCED_INTERVAL_MS = 15000;
private static final int SCAN_MODE_BATCH_LOW_LATENCY_WINDOW_MS = 1500;
private static final int SCAN_MODE_BATCH_LOW_LATENCY_INTERVAL_MS = 5000;

如果我想更改值，是否意味着我应该编译android系统？还有更好的方法吗？

通过启动和停止扫描，您可以自由控制等效扫描窗口和自己在更高级别代码中的间隔。这正是开源Android Beacon Library对其等效可配置参数的作用：

 beaconManager.setForegroundScanPeriod(...);
 beaconManager.setForegroundBetweenScanPeriod(...);
