• I'm currently using the Serial Web API to communicate with the BBC micro:bit and I'm loving it so far!
    There are some nits I'd love to understand though and I thought you folks may know the answer.

    I'm able to connect to the BBC micro:bit device and open the serial port at 9600bps. /me happy
    Then my readLoop doesn't show anything until I turn off serial break for instance. Is this expected?
    Is there another way to "force" the device to send the usual prompt when port is opened?

    Then, the prompt I get contains the "Uncaught InternalError: I2C Write Error 33281" message as shown below. Is there something going on I should fix?

    what 'until I turn off serial break' means? how one can 'turn off' serial break?

    just sending enter does not work? why you want the prompt? you mean just the > or the whole startup logo/banner? btw the logo/banner does not show if you save something (if microbit allows saving code at all) so it may not be good idea to wait for at startup
