Crate esp_idf_improv_wifi 

ImprovWiFi serial provisioning protocol for esp-idf-svc.

This crate implements the Improv WiFi serial provisioning protocol, allowing devices to receive Wi-Fi credentials over a serial (UART) connection from a browser or provisioning tool.

Architecture

The core protocol logic is transport-agnostic — it operates on any std::io::Read + Write stream. An optional esp-idf-svc feature flag provides a UART transport adapter for ESP32.
