# KOTA Sensorbox Technician Tool v0.8
Diagnoza sensorboxa przez USB, wgrywanie firmware z folderu `firmware/` i przygotowanie karty SD.
Działa na Windows 10/11 i macOS 13 (Ventura) lub nowszym, na Macach z Intelem i Apple Silicon.
## Uruchomienie
**Windows:** dwuklik `run_windows.bat`.
**macOS:** dwuklik `run_macos.command`.
Jeśli Finder odpowie, że pliku nie można uruchomić (Google Drive gubi uprawnienie „wykonywalny”),
otwórz Terminal i jednorazowo wpisz `bash ` (ze spacją), przeciągnij plik `run_macos.command` do okna i naciśnij Enter.
Na stałe naprawia to: `chmod +x run_macos.command`.
Przy pierwszym uruchomieniu skrypt proponuje instalację `uv` (menedżer Pythona, instaluje się tylko dla bieżącego
użytkownika) i pobiera biblioteki. Potrzebny jest internet, trwa to 1–2 minuty. Kolejne starty są natychmiastowe.
Środowisko jest poza folderem Google Drive:
`%LOCALAPPDATA%\KotaTechnicianTool\venv-0.8` (Windows), `~/Library/Caches/KotaTechnicianTool/venv-0.8` (macOS).
Sesje, kopie zapasowe flash i ustawienia są w `~/KotaTechnicianTool` (Windows: `C:\Users\<użytkownik>\KotaTechnicianTool`).
## Port sensorboxa
- Windows: `COMx - Sensorbox (native USB) [MAC]`
- macOS: `/dev/cu.usbmodemXXXX - Sensorbox (native USB) [MAC]`
Kabel USB musi przenosić dane (nie tylko ładowanie). Przy restartach z komunikatem o brownout użyj innego portu
lub zasilacza.
## Firmware
Wgrać można tylko pliki `.bin` z folderu `firmware/`. Lista pokazuje datę kompilacji zapisaną w pliku,
najnowszy build jest na górze. Nowy build: wrzuć plik do `firmware/` i kliknij **Refresh list**.
## Testy (dla zespołu)
```
uv run --frozen pytest -q
```
Zmiany: `docs/CHANGES-v0.7.md`, `docs/CHANGES-v0.8.md`.

# Technician tool v0.8 - changes
## Windows + macOS
- Dependencies verified to install on macOS arm64 and x86_64 (uv.lock: PySide6 6.11 universal2 wheels,
requires macOS 13+); Windows unchanged.
- SD card check: macOS `diskutil` reports FAT32 partitions as `DOS_FAT_32` / `Windows_FAT_32`; these are now
accepted (previously a correct card was reported as "not FAT32" on a Mac).
- Unit tests for the macOS serial-port filter (`/dev/cu.*` only) and FAT32 names.
- README.md with launch steps for both systems (incl. the Google Drive executable-bit workaround on macOS);
docs/mac_agent_command.txt updated for a v0.8 test run on a Mac.
## Diagnosis
- Harmless Wi-Fi start-up errors are ignored (rule `benign.wifi_start`): `wifi:sta is connecting, return error`,
`esp_wifi_connect() failed: ESP_ERR_WIFI_CONN`, `Failed to get configured network when updating network
status` (unpaired box).
- Brown-out resets are detected (`E BOD: Brownout detector was triggered`, ROM reports RTC_SW_SYS_RST).
- Service report note = the Diagnosis panel as text (LED, firmware, box self-report, start-up progress with
times, findings with "Seen Nx, first at ... s, last at ... s" and log line), shortened to fit the service
form's 5000 characters.
Not yet run on a real Mac: see docs/mac_agent_command.txt.
