There seems to be a lot of setup, too. I see long pauses during "Detecting libraries used" and "Generating function prototypes". "Compiling Sketch" doesn't show until 17 seconds after clicking on 'Verify'. "Compiling sketch" takes about 5 seconds and then "Compiling core" (using previously compiled ...

Indeed. It seems the whole system is structured badly. I expect when I'm developing an application that if I make a one-line change to one module (e.g., to tweak some parameter) then only that module will be compiled and the new .exe will be running 5 seconds (or less) later. Why anyone things that ...

OK, thanks, that's useful background, etc. In fact I don't need WiFi so maybe I am indeed looking at the wrong chip. I'll take another look at current boards.

I'm currently using 115200 baud for the connection, which is what I thought was recommended. I agree that the IDE (Arduino or ESP-EDF) is not the problem. It would seem that the problem is that far more is being compiled than is necessary just to toggle a LED. Given the size of the binary (nearly a ...

I've used many computers over the years (from mainframes to 8-pin AVR ICs). I'm now starting a new project and would like to base it on the Espressif ESP-S2. For the prototype I have purchased a SparkFun ESP-S2 Thing Plus and the hardware seems to be exactly what I need. However, the support softwar...
