I have been porting an existing pub-sub to Rust (no_std) that runs over serial UART. The published serial protocol is very similar as this one: COBS encoding with CRC32 checksum not CRC16. These docs have a great reference on backpressure for any micro and will be helpful.

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!
