WARNING: EXPERIMENTAL FEATURES AHEAD!
Support for Bluetooth download relies on Web Serial, an experimental browser feature. Web Serial is a work in progress; it may change or be removed in future versions without notice.
By enabling these experimental browser features, you could lose browser data or compromise your device security or privacy.

Supported browsers
- Chrome desktop, version 77 and higher, Windows 10 or Mac OS.
- Edge Insider desktop, version 77 and higher, Windows 10 or Mac OS.
To make sure your browser is up to date, go to the '...' menu, click "Help" then "About".
Next you need to enable the experimental features (this may change in the future)
- go to chrome://flags/#enable-experimental-web-platform-features and enable Experimental Web Platform features
Machine Setup
- pair your EV3 brick with your computer over Bluetooth. This is the usual pairing procedure.
Download over Bluetooth
- go to https://makecode.mindstorms.com/
- click on Download to start a file download as usual
- on the download dialog, you should see a Bluetooth button. Click on the Bluetooth button to enable the mode.
- make sure the EV3 brick is not running a program
- click on Download again to download over bluetooth.
Choosing the correct serial port
Unfortunately, the browser dialog does not make it easy to select which serial port is the brick.
- On Windows, choose
Standard Serial over Bluetooth. There might be multiple of those but only one works. Try your luck! Once you know the COM port number, remember it for the next time around. - On Mac OS, choose
cu.BRICKNAME-SerialPort
Known issues
- We do not detect properly that the program is running on the brick. Make sure to stop the program before starting the download procedure.
- The list of programs on the brick screen is not updated when uploading via bluetooth.
