How many devices can I pair my Livescribe 3 smartpen to?
You can pair the Livescribe 3 smartpen with up to four (4) different iOS 7 (or later) / Android KitKat 4.4.2 (or later) devices, but you can only use one device at a time. If you would like to switch from one paired device to the other paired device, close the Livescribe+ app on the first device, start the Livescribe+ app on the other device, and you should see the light switch from blue, back to green, then to blue again.
If you attempt to pair to a fifth device, the LED will remain solid green and you will be unable to pair until one of the four currently paired device pairings is removed. To do this, please see 83104 - LIVESCRIBE+ - Un-pairing Livescribe 3 from a device.
