Connecting with Bluetooth to LEGO® MINDSTORMS® EV3 apps

You can use Bluetooth to communicate wirelessly between the LEGO® MINDSTORMS® EV3 Intelligent Brick and EV3 Programmer or Programming app!

First, follow these steps to set up Bluetooth on your EV3 Brick:
 

  1. Use the arrow buttons to choose Bluetooth in the 'Settings' screen on the EV3 Brick. A pop-up will appear with a list of options.
  2. Using the up and down buttons, highlight 'Bluetooth', then press the center button. A check mark will appear in the Bluetooth box. You’ve enabled Bluetooth and should see a  icon in the top left of the P-Brick display.

You’ll only be able to connect to an iOS device like an iPhone, iPad or iPod Touch if the 'iPhone/iPad/iPod' option is checked. Make sure this option isn’t checked if you’re using a different device.
 

To connect your device to your EV3 Brick

To view an animation of the connection process, watch the Quick Start Video in the Lobby Menu of the app.
 

  1. Turn on your EV3 Brick.
    • If you’re using a Chromebook, continue to step 2.
    • If you’re using an iOS or Android device, jump to step 5.
  2. Click the status area in the lower-right corner of the Chromebook and then click the Bluetooth icon.
  3. If Bluetooth is off, select 'Enable Bluetooth'. Your Chromebook will now start searching for devices.
  4. Select the EV3 Brick you want to connect to from the list of available devices. It may take some time for the Chromebook to find the EV3 Brick.
  5. Accept the connection on your EV3 Brick, then enter the passkey and press the center button. The default is "1234".
  6. Open a new or existing program in the app.
  7. Tap the 'No Device Connected' icon at the top right corner.
  8. Tap the 'Connect' button.
  9. Select the P-Brick you want to connect to from the list of available bricks.
  10. Accept the connection on your P-Brick, then enter the passkey and press the center button. The default is "1234". Enter the same passkey in the app.
  11. The connection is now established and a '<>' symbol is shown at the top left of the P-Brick display (next to the Bluetooth icon) to confirm the connection.

To disconnect the EV3 Brick from your device, go to the Hardware Page and tap the 'Disconnect' button.
