SiteSurvey Pro v1.0.0

SiteSurvey Pro v1.0.0

First stable release of the SiteSurvey Pro firmware for the Guition NM-CYD-C5 (ESP32-C5, 16 MB flash, 320×240 ST7789 + touch, PSRAM).

Highlights

• Dual-band Wi-Fi survey engine (2.4 / 5 GHz) with live LVGL UI, channel graph, and per-AP detail
• BLE device scanning
• GPS mapping (NMEA on LP-UART) with KML survey export and on-device report generation to SD
• BME680 environmental telemetry
• Alert engine: SSID / BSSID / RSSI-threshold targets, circular on-screen alert log, RGB LED notify
• SD session logging with CSV capture and spreadsheet-safe field sanitization
• Hardened input handling: bounded NMEA parsing, NVS alert-config validation, CSV formula-injection neutralization

Flashing (esptool)

Chip: esp32c5, flash: 16 MB, DIO @ 80 MHz.

esptool.py --chip esp32c5 --port <PORT> --baud 460800 \
  write-flash --flash-mode dio --flash-freq 80m --flash-size 16MB \
  0x2000  bootloader.bin \
  0x8000  partition-table.bin \
  0x10000 SiteSurvey-Pro.bin

The otadata partition may be left erased — the bootloader falls back to the factory partition. A web flasher (esp32.com web-flasher compatible) can flash the same three files at the same offsets.
