常见问题
常见问题
EMQX 通过 MQTT 连接车辆与后端应用，为车队监控、诊断和 OTA 协调等服务路由遥测数据、事件和指令。
MQTT 支持紧凑消息和基于持久连接的双向通信。QoS 等级与会话设置可帮助应用应对间歇性的蜂窝网络连接。
EMQX 可为车载信息服务、远程诊断、OTA 协调、车队管理和电动汽车服务提供消息通信。具体服务逻辑由车辆软件与后端应用实现。
配置 TLS，使用证书或令牌验证车辆与应用，并将访问限制在授权主题内。为遥测数据和指令分别设置权限。
MQTT over QUIC 可帮助兼容客户端更快重连，提高车辆切换网络时的连接连续性。持久 MQTT 会话可保留订阅，并在过期时间与队列限制范围内，将符合条件的消息排队，待重连后投递。车辆需通过本地缓冲保留离线期间产生的待发送遥测数据。
