Good point.

A lot of small setups don’t wire CTS/RTS these days, so I wanted to explore a software-side approach as well. But I agree, proper flow control is still very important.

Thanks for sharing this, that sounds really interesting.

COBS with CRC32 over UART is very close to the kind of problems I’ve been thinking about too. Glad the docs were helpful!

Thanks for sharing this and for the thoughtful summary. Really glad you found the docs and ideas useful!
