Firmware (app_main.c): - UDP command listener on port 5501 (configurable via Kconfig) - Commands: REBOOT, IDENTIFY, STATUS, RATE, POWER - LED status indicator on GPIO2 (off/slow/fast blink/solid) - NVS persistence for send_rate and tx_power settings - Refactored ping to support stop/restart for dynamic rate changes - TX power control via esp_wifi_set_max_tx_power() Pi-side tooling: - tools/esp-cmd: standalone Python3 UDP client for device management Tested on amber-maple (ESP32 v3.1) with ESP-IDF v5.5.2.
