obd/commands.py — Каталог AT-команд ELM327.
|
|
|
|
Все известные команды ELM327 с метаданными:
|
|
- name: имя команды (напр. "ATE0")
|
|
- desc: краткое описание
|
|
- level: минимальный уровень устройства (0/1/2)
|
|
- safe: можно ли слать при пробинге (False для опасных)
|
|
|
|
Принцип:
|
|
- Нет в профиле → не слать.
|
|
- Опасные команды (меняют baud rate, мониторинг) — никогда не пробингуются.
