Can a microbit detect a host computer

[rhubarbdog]

Is there a way to detetmine if a microbit is connected to a laptop via usb. Is there a micropython function the microbit can run to detect a usb host

I don't think so.

I was looking at some pyboard docs. There is a function in the pyb version of micropython. I'm going to raise a feature request

I'm not aware that this would be possible to detect that USB is connected -- the USB functionality is handled by a separate chip on the micro:bit (which runs Daplink). The only pins connected between the NRF51822 (that runs your MicroPython code) is the TX/RX pair for the UART. [Ref: https://github.com/bbcmicrobit/hardware ... _V1.3B.pdf]

On the other hand, if you had something running on the host computer that detected the micro:bit then send it a message over the UART, that might work.

(Note that on the microbit, the single UART is also used by the REPL).
