Why the image displayed on XuanWheel is regular illumination all along rather than the image transmitted by app?

The booting pattern of XuanWheel are some sequentially illuminated LEDs flowing regularly. If there aren’t any images, first make sure each magnet has fixed to the white piece at the end of the light arm and two light arms are firmly connected by the linking wire. When you make sure the magnets have fixed to the white piece, three lights in the middle of the light arm will go out. Then open the menu to the left in app and make sure XuanWheel has connected to app through Bluetooth. In the end, you can change pictures freely by choosing a picture and clicking send button.
