How to Connect to the WeDo 2.0 Smarthub

iOS, Android, and Mac OS:

  1. Start WeDo 2.0

  2. Create a new project or chose one of your old projects.

  3. Open the connect window.

  4. Press the green button on the WeDo 2.0 hub until it appears blinking in the connection window.

  1. Start WeDo 2.0

  2. Open the connect window.

  3. Press the green button on the WeDo 2.0 hub.

  4. Click on the specific hub to connect.

Since it is not possible to highlight which hub are yours we recommend physically labeling and then renaming each Smarthub in the app before starting a class. To rename a Smarthub, access the Connection Center from the app. Next, press the green button on the Smarthub and then press on the Smarthub in the Connection window to connect to it. Now long press on the connected Smarthub and enter the new name.

Q: What can be done if the Smarthub does not appear in the Connection window?

A: If you don’t see a Smarthub in the Connection window, please follow the steps below. If at any point the connection is successful, there is no need to complete the remaining steps. If none of the following steps help, contact your local Consumer Service (visit our website for contact details):

  1. Ensure that Bluetooth is enabled by clicking the Wi-Fi icon in the status area of the taskbar. If the Bluetooth status is disabled, click the ‘Enable Bluetooth’ icon button. Then click the reload icon in the WeDo 2.0 Connection window.

  2. Restart Bluetooth by unchecking ‘Enable Bluetooth’, wait two seconds and then re-enable it. If the Smarthub still does not appear in the WeDo 2.0 Connection window, close WeDo 2.0 and any other programs that may be open. Then click ‘Manage Devices’ below the ‘Enable Bluetooth’ icon button and delete all devices by hovering over each and clicking ‘X’. Reopen the WeDo 2.0 App and check if the Smarthub appears in the device list.

  3. Restart the Chromebook by turning it off and on. Then reopen the WeDo 2.0 App and try connecting to the Smarthub once again.

Windows 10

Windows 10 ‘Fall Creators Update’ and Bluetooth connectivity issues:
With the newly released “Fall Creators Update” for Microsoft Windows 10 we have experienced Bluetooth connectivity issues with WeDo 2.0. Microsoft will roll out a fix for this issue on the 16th of December as part of a Windows update. We recommend that you do not update Windows 10 to the ‘Fall Creators Update’ until the issue has been resolved.

  1. Start WeDo 2.0 and open the Connection window.

  2. Press the green button on the WeDo 2.0 Smarthub.

  3. Click/press the desired Smarthub to connect to it.

  4. When you are prompted to pair the Smarthub, confirm by clicking the ‘Allow’ button and then ‘Close’.


Follow the on-screen instructions if the pairing fails on Windows 10.

  1. Press the green button again if prompted to do so.
  1. If the pairing fails again, click ‘Refresh’. A dialogue will appear asking you to unpair the device. Repeat the pairing process from step 1 above.
  1. When you have successfully paired your Smarthub, it will be shown as connected in the Connection Center.

If your Smarthub connects for a second, but then disconnects again, then try turning off the Smarthub, refresh the connection center and then try again.

Q: My Smarthub is not detected:


  1. Verify that your computer is compatible with Bluetooth 4.0 (also known as Bluetooth low energy or Bluetooth Smart), by checking the manufacturer's website or the documentation that was included with your computer.

  2. Go to the ‘Start’ menu, select ‘Settings’ (the gear icon), then ‘Devices’ and ‘Bluetooth’. Next, delete all previously paired WeDo 2.0 Smarthubs (that are not currently connected) by selecting them in the device list and clicking ‘Remove device’.

  3. Return to the WeDo 2.0 application and repeat the connection process.
