When new software is available, a screen will appear on your Node/Pro's slideshow prompting you to update. The screen will instruct you to hold down the center menu button to begin downloading the “over the air” update. Note - this action only works when you are on the update screen and connected to Wi-Fi.
Don’t hesitate to click! Updates only take a few minutes to download and may offer valuable new features, upgrades and/or sensor calibrations.
