如何设置BLE扫描间隔和Windows没有在Android中选择模式？

Question

我是一个在android的新人。我想在我的android设备中设置BLE扫描间隔和窗口，以便做一个关于邻居发现的实验。我在谷歌搜索的答案，知道有在android's source code约BLE扫描间隔和窗户有些定义如下

/** 
* 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; 

如果我想改变的值，这是否意味着我应该编译Android系统？有没有更好的办法？

您可以自由控制扫描窗口的等价物，并通过启动和停止扫描来更高级别地编码。这正是开源Android Beacon Library确实与同等配置的参数：

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