[FishBot教程] 9.0.6. 雷达驱动及建图测试
-
雷达用小鱼的驱动板功能正常。我尝试用 ESP-12F为模组的ESP8266开发板 驱动雷达 出现timout count: 1提示。对照雷达驱动板原理图和ESP8266开发板引脚图后接线，
VCC 接外部电源5V
GND 接外部电源GND
TX 接ESP8266开发板RXD0
MOTOR 接ESP8266开发板GPIO4
我认为固件拷贝成功，连线正常，应该没有问题，但是提示timout count: 1，可能是什么原因导致的？
@小鱼 -
@小鱼 驱动雷达也是WIFI模式通讯不上，端口占用检查也没问题，USB通讯是正常。 -
@164982458 板子和电脑无法通信，是虚拟机运行系统吗？如果是，需要桥接。与网络也有关系，建议找客服要常见问题汇总的视频讲解。2826778595我的QQ，可以交流以下。
-
@2826778595 是虚拟机，用的桥接模式，端口占用也检查正常。
-
@2826778595 已解决这个问题，IP地址配置错误造成。
-
ping 正常 虚拟机也设置桥街模式 IP设置也正确 为什么还是连接不上呢？！
-
@anzg512 参考这个视频看一下， FishBot常见问题汇总:

博主您好，我可以ping通我的雷达，但是在第一步启动驱动的时候一直停留在 prepare to accept connect。这是为啥呢，好奇怪？烦请大佬指点一二！
-
@2352094992 检查雷达连接，跳线帽，工作模式
-
雷达已上路由

Now YDLIDAR is scanning
等5 -10 分钟左右，出 timout count欢迎鱼香ROS使用雷达驱动系统,注意当前版本为ROS2版本驱动功哦 1)驱动雷达 2)建图测试 3)退出 #? 1 UART2SOCKET:8888->/tmp/fishbot_laser Prepare to Accept connect! 3 <socket.socket fd=6, family=AddressFamily.AF_INET, type=SocketK , proto=0, laddr=('172.17.0.3', 8888), raddr=( PTY: Opened /dev/pts/7 for 0.0.0.0:8888 192.168.1.103', 49 [YDLIDAR INFO] Current ROS Driver Version: 1.4.5 [YDLIDAR] :SDK Version: 1.4.5 [YDLIDAR]:Lidar running correctly !

但是，选 2 测试，又能扫出东西来，虽然有报错

list 有 scan 的会话，但是无效的
fp-macpro@fpmacpro-MacBookPro:~$ ros2 topic list /parameter_events /rosout /scan fp-macpro@fpmacpro-MacBookPro:~$ ros2 topic hz /scan WARNING: topic [/scan] does not appear to be published yet
请问啥问题？和 帖子里说的 timout count: 1 的原因好像不一样啊？
@小鱼 -
@2216096692 我和你有一样的问题呜呜呜
-
@2216096692 偶尔出一个timeout没事，能建图就说明数据没啥问题，另外驱动过后，需要开新的终端测试，看你的图好像退出后再用hz查看，但驱动已经退出了，肯定没有数据
-
保存地图出错

[ros2run]: Process exited with failure 127使用小鱼在B站分享的fishros2的fishbotU盘系统，而且我用一键安装指令重装了ROS2依旧报错。
-
@515261725 你有安装nav2吗，上下文操作有哪些？
-
@小鱼 鱼哥，我也有这个问题，每次都扫描开始一会就会timeout，然后就ERROR了，地图扫描不完整
终端如下：
