The latest firmware for your Neo smarten N2 is V1.02 (February 2015). It is always best to keep firmware up to date to get the best features and use from your Neo smartpen N2. Please see the latest bug fixes and enhancements HERE but to upgrade at anytime simply load the App, turn on your pen, tap the pen icon in the top right of the App to connect the paired pen. It should go solid white. Then go to SETTINGS > PEN INFORMATION > FW UPDATE > and it will check for you. If an upgrade is needed it will do this Over The Air (through your mobile device connection and bluetooth to the pen). Also, please remember to check your updates in the AppStore or GooglePlay to update the app too!
