Yes, the v0.4.1 example uses serial over USB, but you could do the same over the UART. You probably want to use something like `BufferedUarte`: https://docs.embassy.dev/embassy-nrf/git/nrf52832/buffered_uarte/index.html, the reason is that you need to "always be listening" so you don't lose bytes/messages, and using the buffered version is the easiest way to do that.
