Zabavam sa s ESP32. Programujem to cez Arduino IDE a narazil som na problem.
Rad by som poslal zaznam ze na danom pine sa zmenil signal cez HTTP request.

Problem je ze vzdy ked by mal poslat request ze sa nieco zmenilo tak to cele spadne.

Ani google mi nepomohol ani chatGPT. Kde je zrada? Ma niekto skusenost?
