espup

Ya, the tooling is improving (e.g. https://github.com/esp-rs/espup) - but still, the experience with Rust is always interesting; I try it every few months, then give up as it breaks, sometimes check tinygo, then realize it's still missing wifi/bt support, and go back to c. Micropython is interesting, but also the developer experience around the tooling isn't great. I was spoiled with rails imho. (if tinygo supported more than one core, and had wifi/bt support on esp32, I'd not be looking back that often)

Thanks for mentioning it. I already tried using it a few months ago and brushed it off as still being a WIP, but it still didn't work when I tried again just a few days ago. Asking in the Matrix chat when first trying it sadly only got me a "works for me" from the developers. What Espressif is doing with their esp-idf and porting it to Rust is promising, but overall it still needs work. Using the toolchain to develop on the ESP32 was at least slightly painful half a year ago before they introduced espup[1], having to keep a patched LLVM around etc., and supposedly support for their Xtensa architecture is coming to LLVM soon[2] so this will improve in the future. I'd also love to see Bluetooth support in esp-idf-svc[3], but they seem to be lacking people with the required knowledge to design and implement an abstraction for it[4]. [1]: htt

Have you tried with espup(https://github.com/esp-rs/espup)? We`ve updated Xtensa tooling not long ago, for more details have a look at the book: https://esp-rs.github.io/book/installation/installation.html...
