Occasionally, the stylus will disconnect for whatever reason, either the stylus is out of range, turned off, or has gone to sleep after a period of inactivity to preserve battery power.

Once connected, you are ready to either customize the stylus' settings or start sketching. Turn the power on on your stylus within close proximity to your device. If your pen doesn't appear in the list, SketchBook Pro will behave as if None is set. In the Preferences > Pen Connection, select your stylus model from the list of pens. Launch SketchBook Pro and go to the Preferences. To connect your stylus to SketchBook Pro on iOS, you need to go to your iOS Settings and select Settings > Bluetooth to enable it. If your stylus is not working with your iPad, check to ensure it is supported and charged. SketchBook Pro for iOS only supports the Apple Pencil on iPad Air and iPad Pro. SketchBook Pro for Android only supports S Pen on Samsung supported devices. If you are looking for input devices that will give you the best experience with SketchBook Pro on either desktop or mobile, see Auxiliary tools you can use with SketchBook Pro.
