        <title>Web Bluetooth micro:bit UART</title>
        <h1>Web Bluetooth micro:bit UART</h1>
        <p>Scan Bluetooth devices (using "BBC micro:bit" as namePrefix filter). Allows to interact with the micro:bit using the Bluetooth UART service.<br>Example MakeCode micro:bit project <a href="https://makecode.microbit.org/_9TPWorUACfpp" target="_blank">here</a> (or <a href="https://makecode.microbit.org/#pub:_9TPWorUACfpp" target="_blank">here</a> to open in MakeCode directly). In this example, when the micro:bit receives a string via BLE UART, it inverts it and sends it back via BLE UART.</p>
