LEGO® Education SPIKE™ Prime FAQs
What's the maximum number of students recommended per set?
We recommend one set for every two students in a classroom setting. However, the lessons can easily be completed with more students per set, or even one student per set.
In which languages is the LEGO® Education SPIKE App available?
The SPIKE App is available in 21 languages: English (US), English (UK), English (AU), Chinese, Japanese, Russian, German, Dutch, Finnish, Swedish, Norwegian, Danish, French, Italian, Korean, Portuguese, Spanish, Polish, Turkish, Vietnamese, and Arabic.
Where can I find additional support?
SPIKE Prime help can be found within the SPIKE App and online here. You're also welcome to contact our Consumer Service & Technical Support.
There's an unnumbered bag of bricks in my set – what’s it for?
We've included an extra bag containing some of the smaller elements that are crucial to the building process. We know from experience that these are often the first elements to go missing. This bag can also be purchased separately (2000719 - LE Replacement Pack Prime).
How do I connect the SPIKE Prime Hub for the first time?
The first time you connect your Hub to the SPIKE App, you'll have to install the latest operating system (OS). You'll be automatically prompted to begin the OS update. This initial update can only be done via a USB connection on a Windows or Mac device. Subsequent updates can be done via Bluetooth from any compatible device.
How do I update the Hub operating system (OS)?
The Hub OS is updated via the SPIKE App. Whenever a new Hub OS becomes available, a button labeled Update will appear in the Dashboard tab on the SPIKE App project page. Simply press this button to download and install the updated Hub OS. Make sure that you always have the latest Hub OS installed.
Can I update the Hub operating system (OS) via Bluetooth?
Generally, yes. But the very first time your Hub is connected to the SPIKE App, the OS must be updated via a USB connection on a Windows or Mac device. Subsequent updates can be done via Bluetooth from any compatible device.
How do I reset the Hub to factory settings?
To reset your Hub to factory settings, press the Hub Connection Icon on the Programming Canvas, press the More Button (···) in the Dashboard tab and select Reset Settings. Press OK to confirm the reset, or Cancel to keep the current settings. Be careful - resetting your Hub will delete all of your programs, and they can’t be recovered!
How do I rename the Hub?
Giving each Hub a unique name helps you differentiate between multiple Hubs (e.g., when using Bluetooth communication). When connecting to a Hub that hasn't yet been renamed, the SPIKE App will automatically ask you to rename it.
In order to rename a Hub that you have already named, you must first remove it from your desktop or tablet as a paired Bluetooth device or clear the device's Bluetooth cache.
Once the Hub is removed as a Bluetooth device you can press the Hub Connection Icon on the Programming Canvas and connect your Hub. Then select Rename Hub in the Dashboard tab and enter the new name. Press OK to save your changes.
How do I use Bluetooth to connect the Hub to a device?
Press the Bluetooth Button (top right) on your Hub. In the Connection Center in the SPIKE App, select your Hub from the list of all available Hubs. When your Hub has been connected, the connection manager will close automatically. A notification will appear in the programming area confirming that the connection has been successfully established.
How stable is Bluetooth connectivity in a classroom setting?
SPIKE Prime Bluetooth connectivity can be affected by the type of device used. The connection process can be vulnerable in classroom settings where the same Hubs are connected to different devices over time.
LEGO Education continuously strives to improve SPIKE Prime Bluetooth connectivity across operating systems with periodic updates to the SPIKE App and the Hub firmware. As we work on further improvements, we recommend the following best practices to help mitigate potential challenges with Bluetooth connectivity.
Physically label the Hubs for unique identification.
Update the Hub OS prior to class/use.
Rename the Hubs prior to class/use—see the Hub Renaming Guide.
Always pair the Hubs with the same devices (if possible).
Connect the devices to the Hubs one by one.
Adjust the Sleep Mode time on the device to ensure the screen stays active for at least 10 minutes to prevent the Hub from disconnecting from the device.
If a device is used to connect to multiple Hubs or is slow in finding the Hub name, clear the device’s Bluetooth cache frequently (particularly on Windows and macOS)—see the Quick Guide for Clearing Bluetooth Cache below.
If a Hub is accidentally paired with the wrong device, you’ll need to remove the paired Hub from the device’s settings—see the Quick Guide for Clearing Bluetooth Cache below. You can’t remove paired devices from within the SPIKE App.
Use a USB cable connection if Bluetooth connectivity continues to be challenging (for Windows and macOS only).
For general guidance on how to connect the Hub to different types of devices via Bluetooth, please see the Bluetooth Connection Guide.
Why do I need to grant permission for "Location Services” on Android and Chromebook?
The Bluetooth Classic and Bluetooth Low Energy Technology, which enable your device to communicate with the Hub, require access to the device’s geolocation services. It’s a technical requirement that’s out of LEGO Education’s control. This access doesn’t collect or save any user data. It simply enables the technology to work.
How do I clear the Bluetooth cache?
First, make sure that Bluetooth is enabled on both the Hub and your device—and that the Hub is sufficiently charged.
In the Start Menu on your device, select Settings.
To remove all unnecessary Bluetooth devices, select one device at a time and press the Remove device button. (If the device is in use, it will show as Connected. Otherwise, it will show as Paired.)
For further guidance, please refer to Microsoft’s support for troubleshooting Bluetooth in Windows 10.
To enable the Bluetooth icon in the menu bar, go to System Preferences, select Bluetooth, and check Show Bluetooth in the menu bar.
While holding ALT + Shift, click the Bluetooth icon in the menu bar.
Select the Debug submenu.
Select Reset the Bluetooth module.
Go to the Settings app.
To remove all unnecessary Bluetooth devices, click the blue “i” icon for devices listed under My Devices, and select Forget this device.
Restart the iPad.
Android (simple clearing)
Go to the Settings app.
To remove all unnecessary Bluetooth devices, click on the Gear icon for devices listed under Paired Devices and select Unpair or Forget.
Restart the Android tablet.
Android (thorough clearing)
Go to the Settings app.
Tap the More icon (···) and then select Show system apps/processes.
In the list of apps, select Bluetooth or Bluetooth Share (you’ll see the Bluetooth icon).
Select Clear cache.
Restart the Android tablet.
How do I maintain SPIKE Hub health for the best performance?
The SPIKE Prime Hubs operate best when fully charged. This ensures that students can access the building and coding experience—and the Hub can undergo software updates when needed. Before the first use and following regular classroom use, the Hubs will need to be recharged using the USB cables found in the sets. The Hubs will automatically begin charging as soon as they’re connected via USB cable to any USB port or USB power supply. It’s most efficient to charge multiple Hubs simultaneously using school-approved multi-USB port charging devices or power supply devices that allow for multiple power connections.
Charging time (from empty to full) is approximately 3 hours. This will vary depending on the type of USB charger used.
How do I manage firmware updates on the SPIKE Hub?
Firmware updates can either be mandatory or optional.
Mandatory updates will show an alert dialog that blocks the user from doing anything but updating the firmware. We only use this approach when necessary (e.g., to introduce new features in the app that are dependent on a firmware update).
Optional updates will show a notification banner in the top right of the app window. The notification banner allows the user to choose to install the update or wait to do it at another time.
Once the user starts an update, there's no way to pause it. The only way to cancel it is to turn off the Hub. Doing so will require the user to start the update process over again.
What type of batteries can I use in the Hub?
You can only use the special Rechargeable Battery that comes with the Hub and the SPIKE Prime Set. The battery is charged using the micro USB cable that’s included in the set. The Rechargeable Battery is also available to buy as a separate item (45610 – LEGO Technic™ Large Hub Battery).
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 charging time will depend on the type of USB charger that's being used.
- Chargers with Dedicated Charging Port (DVP) or Charging Downstream Port (CDP): Approx. 2 hours charging time (from empty to full). The USB ports on most newer laptops, and genuine OEM chargers from trusted brands like Apple or Samsung are typically one of these two types.
- Chargers with Standard Downstream Port (SDP): Approx. 4.5 – 5 hours charging time (from empty to full). Generic chargers are often this type.
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 Center Button light up with a color-coded error message. Here's an overview of the error messages and how to fix them.
The Center Button is flashing red
There was an error on your Hub or with the program it was trying to run. This can likely be solved by fixing errors in the your program, and running it. In rare cases, you might have to restart the Hub by holding down the Center Button for approximately 3 seconds.
The Center Button is flashing orange
Your Hub's battery is running low. Connect the Hub via the USB cable to begin charging the battery.
The Center Button is green
Your Hub has stopped working, - most likely due to a lost connection. Restart it by holding down the Center Button for approximately 3 seconds.
The Center Button is blue
Your Hub needs an update that requires a USB cable connection. Connect your Hub to a device via USB cable, and start the Hub OS update in the SPIKE App.
The Connection Button is flashing violet/green/blue
Your Hub OS has been recently updated, and your Hub needs to be restarted. Restart your Hub by holding down the Center Button for approximately 20 seconds.
Can I use any micro USB cable to connect the Hub to my device?
No, you must use a USB 2.0 cable with a Male- to- Micro B connector and an AWG 24 wire gauge. We strongly advise that you only use the micro USB cable that was supplied as part of the SPIKE Prime Set. This can also be purchased separately (45611 - LEGO Technic Micro USB Connector Cable).
The SPIKE App
Which coding language is the SPIKE App built on?
The SPIKE App uses an intuitive drag-and-drop coding language that’s based on Scratch. Some of the blocks are identical to the ones that are used in Scratch 3.0, while others have been specially developed to interact with the SPIKE Prime hardware.
Are the programs created in the SPIKE App compatible with Scratch 3.0?
No, you can't use programs created in the SPIKE App with Scratch 3.0 (and vice versa).
Which operating systems are compatible with SPIKE Prime?
The SPIKE App is available for Win10, Chrome OS, iOS, Android, and macOS. .
Why isn't SPIKE Prime available for Windows 7?
Microsoft implemented Windows 7 “end of life” in January 2020, meaning that it has discontinued all support, including paid support; and all updates, including security updates. LEGO Education has therefore decided to focus on Windows 10.
Why is there no USB support for the Chromebook version of the SPIKE App?
SPIKE Prime has been brought to Chromebooks as a “Ported Android App,” which Google recommends as the most sustainable. Currently, Ported Android Apps don't support USB connectivity.
Which version of Python is used in the SPIKE App?
The Python editor in the app uses MicroPython, which is an efficient and commonly used version of the Python language that's optimized to run on microcontrollers or small computers. The majority of Python's language features are found in MicroPython. However, MicroPython doesn't contain the entire Python library by default.
How can I download the SPIKE App for Chromebooks?
The SPIKE App for Chrome can be downloaded from the Google Play Store. Some schools and districts restrict access to the Google Play Store on student devices. In these cases, there are extra steps that the school’s Google admin must take to install the SPIKE App on student devices. For further guidance on how to manage access to trusted apps, like the SPIKE App, please refer to Google’s support for deploying apps to managed users https://support.google.com/chrome/a/answer/7131624?hl=en.
Alternatively, users can access the BETA SPIKE Web App through the Chrome browser at LEGO Education SPIKE.
How do I resolve issues with opening the SPIKE App on Chromebooks?
Users having trouble opening the SPIKE App on a Chromebook might need to update the Android System WebView. This small component can be updated from the Google Play Store like any other app:
- Open Google Play Store.
- Go to My apps (or search for System WebView).
- Go to updates, find Android System WebView, and press Update.
Why can’t I install the SPIKE App on PC in Windows 10 32bit?
When installing the SPIKE App in Windows 10 32bit, the user gets the following error: "This installation package is not supported on this type of processor." The only workaround is to install the SPIKE App on Windows 10 64bit instead. The SPIKE App doesn’t support Windows 10 32bit.
Why am I encountering Sound Block issues on iOS?
If you are experiencing an issue with the Sound Blocks on iOS where the sound will suddenly stop working, we would recommend updating the SPIKE app to the latest version 2.0.5 for resolving this issue.
Is SPIKE Prime compatible with LEGO MINDSTORMS Education EV3?
The SPIKE Prime hardware does not offer backward compatibility with LEGO MINDSTORMS Education EV3 because the plug system is different. LEGO MINDSTORMS Education EV3 is based on an RJ12 plug system, whereas SPIKE Prime uses the LPF2 plug system, which is a proprietary LEGO plug system. There will also be no backward compatibility on the programming side.
Is SPIKE Prime compatible with WeDo 2.0?
Even though the hardware from SPIKE Prime and WeDo 2.0 share the same plug system and therefore fit together, you can't combine the SPIKE Prime and WeDo 2.0 hardware and use the SPIKE App or WeDo 2.0 App to code them.
Can I use SPIKE Prime in FIRST® LEGO League and WRO?
Yes, it’s permitted for use in FIRST LEGO League starting in the 2019 season and in WRO starting in 2020. Future competitions will be developed for use with both LEGO MINDSTORMS Education EV3 and SPIKE Prime.
