Worked on enhancing the documentation for the SMP UART transport in the kholia/zephyr repository, focusing on improving clarity and reducing ambiguity for integrators. Addressed a documentation bug by correcting the calculation of the maximum raw body size, updating it from MTU minus three to MTU minus five, and clarified the size constraints for partial-final frames to account for protocol overhead. Utilized reStructuredText (rst) and documentation best practices to ensure technical accuracy and maintainability. These changes aimed to streamline developer onboarding, prevent misconfiguration, and support better interoperability by providing precise, actionable guidance for those integrating or maintaining the transport layer.
