Hi,

I am aware that it is only a BETA feature. But unfortunately, the EV3 cannot be connected via Bluetooth when using [https://makecode.mindstorms.com/](https://makecode.mindstorms.com/). In the JavaScript Console the following error is displayed:

Failed to execute ‘open’ on ‘SerialPort’: Failed to read the ‘baudRate’ property from ‘SerialOptions’: Failed to read the ‘baudRate’ property from ‘SerialOptions’: Required member is undefined.

Best regards
