Programming Bluetooth Support

LEGO® MINDSTORMS® Education EV3

In EV3 Programming, you can connect your device with an EV3 Brick via Bluetooth in three ways:

EV3 Bluetooth connection icons

  1. Start Block (on the Programming Canvas) 
  2. No Brick Connected icon (in the top right hand corner of the Programming Canvas) 
  3. Available Bricks button (on the Hardware Page)

When clicking/tapping on any of the above, a “Connect EV3 Brick to device” dialog box appears with connection instructions. Once done and the blue Connect button is clicked, a small empty “Select An Accessory/Device” dialog appears. This indicates that your device is searching for any available EV3 Bricks. If your device and EV3 Brick have not been connected before, this may take a minute. Please do not close the dialog. When your EV3 Brick appears as available, select it and click Pair. Confirm the pairing on your EV3 Brick. After a few seconds, your EV3 Brick and device should be connected. 

Troubleshooting - iOS

If your EV3 Brick is not listed in the “Select An Accessory/Device” dialog box, please make sure Bluetooth is enabled and visible on your EV3 Brick and that you have checked the iPhone/iPad/iPod mode as shown below.

If your EV3 Brick still does not appear in the “Select An Accessory” dialog box, try to connect your EV3 Brick to your iPad from the Settings menu on the iPad by using the following steps:

  3. Select your EV3 Brick and click Pair 

  4. Confirm the pairing on your EV3 Brick
