蓝牙和低功耗蓝牙配置文件（Bluetooth and BLE profiles）

代码示例（使用Android Bluetooth API）：

//搜索BLE设备 private void scanLeDevice(final boolean enable) { if (enable) { //扫描5秒后停止 mHandler.postDelayed(new Runnable() { @Override public void run() { mScanning = false; mBluetoothAdapter.stopLeScan(mLeScanCallback); invalidateOptionsMenu(); } }, SCAN_PERIOD);

    mScanning = true;
    mBluetoothAdapter.startLeScan(mLeScanCallback);
} else {
    mScanning = false;
    mBluetoothAdapter.stopLeScan(mLeScanCallback);
}

}

// 搜索到BLE设备之后的回调函数 private BluetoothAdapter.LeScanCallback mLeScanCallback = new BluetoothAdapter.LeScanCallback() { @Override public void onLeScan(final BluetoothDevice device, int rssi, byte[] scanRecord) { runOnUiThread(new Runnable() { @Override public void run() { mLeDeviceListAdapter.addDevice(device); mLeDeviceListAdapter.notifyDataSetChanged(); } }); } };
