The article is really light on actual details.

Basically, this is a company who uses ESP32 to read serial data from batteries using UART and retransmits it in json over MQTT. They apparently had buggy C code to do that (for unspecified reasons) and successfully rewrote that in Rust.

Conclusion, you can write ESP32 code in Rust. No information on what that actually entails sadly.

Some more information on ESP32 on Rust. Espressif (the organisation behind ESP32) spent effort to properly support Rust on their chips, see their documentation: https://docs.esp-rs.org/book/

Another nice resource for Rust embedded is https://embassy.dev/ which also supports STM32, Nordic chips, and RP2040.

IMO, the coolest feature about Rust embedded is that Async Rust works! This makes building a HTTP server for your embedded chip easy.

Most embedded code is pretty bad at async - that could be a game changer.
