 * 通过 USART1 接收简单文本命令，用于现场调试:
 *   RESET/OTA          - 复位整机
 *   RECOVERY           - WiFi模块 AT+RESTORE 忘掉已存热点(测试SmartConfig) + 复位
 *   INFO               - 打印 MQTT 配置信息
 *   STATUS             - 打印继电器状态
 *   R1ON ~ R4OFF       - 单路继电器开关
 *   ALLON / ALLOFF     - 全部继电器开关
 *   HELP               - 显示支持命令
