I don't know what the issue is but I've tried esp-wifi on the ESP32-C3 with the examples and nothing would run. It's a bummer since I'd have liked to leverage the Bluetooth support for my project.
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].
That’s about my experience too. Which is far too fiddly for us to rely on at work for production tasks. I basically keep checking back every six months or so: I’m hopeful that in a year, year and a half, I could replicate what we’ve done with our project on esp-rs entirely. Fingers crossed anyway, but right now there are quite a few showstoppers.
