Esp32 Serial Commands

If you're testing ESP32 firmware and tired of physically pressing buttons, this sends commands over USB serial to trigger actions programmatically. You add a simple command parser to your device code (works with ESP-IDF or Arduino), then echo commands from your terminal to simulate button presses, screen changes, or whatever you wire up. The skill includes actual device-side code and bash scripts for stress testing, like sending 100 presses in a loop or running hour-long stability tests. It's straightforward automation that beats reflashing or physical interaction when you're debugging. The approach is basic but that's the point, it just works without extra dependencies.
