Ros-core2-client issue

I’ve got a problem to communicate with my Rosbot, after investigation it seems that there is a problem with ros-core2-client.
I’ve try this only command:
/opt/husarion/tools/rpi-linux/ros-core2-client /dev/ttyCORE2

and the response is:

Traceback (most recent call last):
File “/opt/husarion/tools/rpi-linux/ros-core2-client”, line 39, in
from rosserial_python import SerialClient, RosSerialServer
File “/opt/ros/kinetic/lib/python2.7/dist-packages/rosserial_python/init.py”, line 1, in
from SerialClient import *
File “/opt/ros/kinetic/lib/python2.7/dist-packages/rosserial_python/SerialClient.py”, line 51, in
import diagnostic_msgs.msg
ImportError: No module named msg

Is there someone who know what happen ?

Hi Baptiste,

Can I ask you to add new GPG key (using this manual) and execute these commands in terminal:

sudo apt update
sudo apt dist-upgrade

It should resolve your problem.

Best regards,

Hi Hubert,

I tried your commands but the problem still intact.

Hi Baptiste,

I did a lot of tests, but I could not reproduce your problem and I do not know how to fix it. The fastest way to resolve your problem will be flash SD card with new image. If we don’t facing a hardware issue it will work. Could you flash your card following tutorial from here?

Please let me know the results.

Best regards,
Hubert

Hi Hubert,

Sorry for the very long delay, I forget to answer.
I flashed another SD card and the Rosbot works fine. I don’t know what happened.
