What I Built

ESP32 firmware with USB CDC serial console, PPP networking stack, FreeRTOS task tuning, and a custom partition layout for an 8MB flash target.
Python desktop GUI for technicians to connect to RMS devices over serial, edit configuration fields, test LEDs, and confirm device state — no CLI required.
Serial port detection to auto-discover connected devices without manual COM port selection.
