Troubleshooting the The Hub and FAQs

Do I need to update the Hub’s operating system (OS) before getting started?
When a user connects a Hub to their device, the app verifies compatibility with the installed version of the OS. If it’s not compatible, the app notifies the user that the OS must be updated before continuing.

How do I update the Hub operating system?
Hub updates differ depending on the device you’re using. To update your Hub, simply follow the instructions below or the in-app instructions that will appear when an update is needed.
Note: whenever possible we recommended using a USB connection for updating.

Chrome
Connect the Hub to your Chromebook using the USB cable supplied with the SPIKE Prime Set.
Open the Chrome browser and run the online updater at https://education.lego.com/en-us/downloads/spike-app/software/.

Can I update the Hub operating system (OS) via Bluetooth
Yes, but whenever possible we recommended using a USB connection during the update process.

How do I rename the Hub?
When connecting to a Hub that hasn't been renamed, the LEGO® Education SPIKE™ App will automatically ask you to rename it. Giving each Hub a unique name will help you differentiate between multiple Hubs in close proximity (e.g., when using Bluetooth).

What type of USB power chargers do you recommend to use for charging the Hub?
We recommend using a high-quality power charger from a reputable brand because these are often DVP- (dedicated charging port) or CDP- (charging downstream port) type chargers.

What is the charging time for the Hub battery?
The Hub uses standard USB 500mA charging current. The charging time (from empty to full) is approximately 3 hours.

How can I preserve my Hub's battery life?
If the Hub isn't going to be used for an extended period, we suggest fully charging the battery before storing it. Storing the Hub with a completely drained battery is not recommended. You can also extend the battery life by removing the battery from your Hub before storing it.

What do the Hub's color-coded error messages mean?
If you’re having issues starting or connecting your Hub, you might see the Light display a color-coded error message. Here's an overview of the error messages and how to fix them.
