You can use Bluetooth to communicate wirelessly between the LEGO® MINDSTORMS® EV3 P-Brick and EV3 Software! Bluetooth has a shorter range than Wi-Fi, but uses less power and you don’t need a wireless router to set it up.
Follow these steps to set up Bluetooth on your P-Brick:
- Use the arrow buttons to choose Bluetooth in the 'Settings' screen on the P-Brick. A pop-up will appear with a list of options.
- Using the up and down buttons for navigation, highlight 'Bluetooth', then press the center button and a checkmark will appear in the Bluetooth box. You’ve enabled Bluetooth and should see a icon in the top left of the P-Brick display.
If the 'iPhone/iPad/iPod' option is checked, you won’t be able to connect to anything except an iOS device like an iPhone, iPad or iPod Touch. For all other connections, keep this unchecked.
To connect your software to your P-Brick
macOS
- Start the LEGO® MINDSTORMS® EV3 Software and connect your P-Brick to your Mac using the USB cable.
- In the EV3 software, make your way to the Hardware Page and click Refresh.
- A new window will pop up and list all previously connected and available P-Bricks. It might take a few minutes before your P-Brick is shown. Find the one you want to connect to and select it.

- The Bluetooth Setup Assistant will search for all devices available over Bluetooth. It might take a few minutes before your P-Brick is shown. When it is, choose it and click 'Continue'.
