I started looking more closely at the firmware part! Actually, I’ve never worked with ESP-IDF, so I’m going to take another good look at it and refresh myself on things I might not be prepared enough for.

I grabbed it to check out and study with the example code "Blynk Led" —the one in the picture is a different one. It’s to control the internal LED with the BOOT button.

I’ve seen a bit, and RTOS seems really cool, here it’s FreeRTOS. But you need to pay attention and be aware, understand how things work. I feel like it’s going to be a long and tough road… but let’s go! The good thing is that we have AI to help us out and clarify points, test stuff, and so on.
