Hi,
I am using Raspi Pi4 and Arduino Due with serial communication.
I can send command from Raspi to Dc motor in Arduino and receieve sensor Data from Arduino to Raspi.
I am also using another program to work with Ros in Raspi, also it works fine.
Now, the aim is to use the Data aquired from sensor in Arduino Due (Data that are in Serial com in Raspi),
in Raspi to share that in Ros Noeud.
I get the error in puicture in attachement.
Could someone help to reslve that ?
Many thanks by advance.

Could you please try updating the "/etc/environment" file on Pi as shown below?
1) Go to Pi's terminal
2) sudo nano /etc/environment
3) Add the below code to the end of that file.
MW_ROSDISTRO=melodic
Note: if you have installed a different version of ROS, instead of melodic, please update the above line accordingly.
Ideally, ROS would get installed at /etc/ros/<version>
Please give it a try
Thanks,
Prasanth
