可以使用Android的BluetoothLeScanner类和ScanFilter类设置特定的广播通道进行BLE设备扫描。以下是示例代码：

//使用Android的BluetoothLeScanner类扫描BLE设备 BluetoothLeScanner scanner = BluetoothAdapter.getDefaultAdapter().getBluetoothLeScanner();

//设置广播过滤器ScanFilter以扫描特定广播通道 List filters = new ArrayList<>(); ScanFilter filter = new ScanFilter.Builder().setServiceUuid(ParcelUuid.fromString("0000180F-0000-1000-8000-00805f9b34fb")) .build(); //设置为广播通道UUID为180F filters.add(filter);

ScanSettings settings = new ScanSettings.Builder().setScanMode(ScanSettings.SCAN_MODE_LOW_LATENCY) .build(); //设置扫描模式为超低延迟

//调用startScan方法开始BLE设备扫描 scanner.startScan(filters, settings, scanCallback);
