@anoddy1999 雷达板的IP呢，两者要分开配哦，另外最好单独发帖，跟贴容易被吃掉

@小鱼这个雷达转接板的源码用什么打开呢，我用plateformio打不开

@yongyong 看README

等待修复

我在运行完代码开启rviz想查看雷达的scan，结果出现以下警告

@zbohao7 在拓展2：FishBot配套雷达驱动教程（源码版）中说：

[ydlidar_node-1] [WARN] [1741712184.172818572] [ydlidar_node]: New subscription discovered on topic '/scan', requesting incompatible QoS. No messages will be sent to it. Last incompatible policy: RELIABILITY_QOS_POLICY

可以忽略，具体原因参考书籍第十章

鱼哥，雷达转接板，是将雷达数据通过串口转WiFi，直接在电脑上通过虚拟的串口将进行把数据转化成scan话题的吗？没有经过mircoros发布到电脑agent上面吗？直接将雷达数据通过主控板驱动板esp32s3的WiFi发出可以吗？

@945717873 没有经过agent，雷达板自带wifi
