以下是一种可能的解决方案,包含Android中定期进行蓝牙低功耗扫描的代码示例:
private BluetoothAdapter bluetoothAdapter;
bluetoothAdapter = BluetoothAdapter.getDefaultAdapter();
private static final long SCAN_PERIOD = 10000; // 扫描间隔时间(毫秒)
private boolean scanning = false;
private void startScan() {
if (!scanning) {
scanning = true;
bluetoothAdapter.startLeScan(leScanCallback);
handler.postDelayed(stopScanRunnable, SCAN_PERIOD);
}
}
private void stopScan() {
if (scanning) {
scanning = false;
bluetoothAdapter.stopLeScan(leScanCallback);
}
}
private Handler handler = new Handler();
private Runnable stopScanRunnable = new Runnable() {
@Override
public void run() {
stopScan();
}
};
private BluetoothAdapter.LeScanCallback leScanCallback =
new BluetoothAdapter.LeScanCallback() {
@Override
public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) {
// 处理扫描到的蓝牙设备
runOnUiThread(new Runnable() {
@Override
public void run() {
// 在UI线程更新UI或执行其他操作
// device.getName() 获取设备名称
// device.getAddress() 获取设备地址
}
});
}
};
startScan();
@Override
protected void onPause() {
super.onPause();
stopScan();
}
以上代码示例演示了如何在Android中定期进行蓝牙低功耗扫描。你可以根据自己的需求进行修改和扩展。
