Bluetooth UART Console feature

Description

Stream Bluetooth UART data into the console. UART data is typically emitted by a BLE capable device like the BBC micro:bit

How to enable it?

• Open a browser that supports Web Bluetooth. See https://caniuse.com/#feat=web-bluetooth. On Windows, you'll need Chrome 70+.
• Go to the gearwheel menu and click on Pair Bluetooth
• Select your device and pair

As soon as UART data is received the Console data button will show up.

If you cannot see that button and you editor supports this experiment, go to About, then click Experiments and Bluetooth Console. If you cannot see this card, your editor does not support yet this feature.

micro:bit example

The following code streams the acceleration value. Don't forget to add the bluetooth Extension to use this code.

bluetooth.startUartService()
basic.forever(function () {
    led.toggle(0, 0)
    bluetooth.uartWriteValue("a", input.acceleration(Dimension.X))
})

Feedback

Do you use this feature? Is there something you'd like to change? Did you encounter issues? Please drop a comment on this issue to send us your feedback.

Start by locating the gearwheel menu's Pair Bluetooth flow, the Console data button, and the About > Experiments > Bluetooth Console setting. Check the Web Bluetooth and micro:bit UART behavior described here; because the issue requests feedback rather than a specific change, confirm the desired scope and completion criteria before implementing anything.
