1 month ago Hey there, I wanted to ask if it even runs on ROS Noetic? I have ros noetic. I have already simulated my ev3pick and place robot using ROS Noetic and gazebo. Now I want to implement it by customising nodes with the help of Yokto h4r controller. Can I even do that? or does it only runs on ros Kinetic?
Maybe its useless ti ask for help here but i give it a try So anyway my problem is that after i ssh to my ev3 and strat the ev3_manager and then i launch a launch file from my PC i get md5sum mismatch on my ev3 and its disconnected for this This is what i get on my ev3 : root@Targonca:~# ev3_manager Port: in4 Mode: angle Publish rate: 10 getFilePTR opening: /sys/class/lego-sensor/sensor0/driver_name 0x597a0 str:lego-ev3-gyro Str No: 0:lego-ev3-color Str No: 1:lego-ev3-gyro<--- Driver Name: 3 [ERROR] [1455389241.402820121]: client wants service /Targonca/controller_manager/switch_controller to have md5sum b29a7abc673b2c54c14b54e50f8d06a5, but it has 5e857dedf71d6f337975e15a1e7cfdd8.

and this is what i get on my PC: kristof@kristof-MS-7D22:~/catkin_ws$ roslaunch h4r_ev3_launch gyro.launch ev3_hostname:=Targonca ... logging to /home/kristof/.ros/log/1926c4a8-79a3-11ee-8e54-39cccc692a25/roslaunch-kristof-MS-7D22-35470.log Checking log directory for disk usage.

i don't know what is the problem my bet is on the ros version (using noetic ubuntu 20.04.06) but i'm not sure i hope you could help me or just say what version of ros should i use
