I’m experimenting with different ways to program an ESP, including native code, MicroPython, Lua on RTOS, JavaScript, and WebAssembly. I want to compare these options in terms of execution time, CPU load, memory usage, and storage footprint.

What’s the best way to set up practical benchmarks across ...

I’m interacting with an HTTP server hosted on an ESP, mainly to upload new firmware, but also to get some status information. Everything works when the website that communicates with the ESP runs over plain HTTP, but once I serve the website over HTTPS, direct communication with the ESP breaks.

The ...

Hey again! I have recently noticed a few projects using WebAssembly interpreters to upload to ESP devices which seem to be quite fast when it comes to replacing/uploading programs.

How much of the ESP API and libraries do things like the [ESP-WASMachine][https://github.com/espressif/esp-wasmachine ...

Thanks for the answer. If possible, could you share a description of the approach you are working on?

I'm building a block-based web editor for microcontrollers like the ESP32 and want to make the experience more interactive by avoiding the full flash cycle. In my research, I’ve found interpreted options like MicroPython, which allow updates without reflashing the entire program—but they require ...
