Hi
I have an arduino zero, connected to native port, Arduino IDE 1.8.7, Ubuntu 18.04 and ROS melodic.
I did the tutorial Hello World, to publish something to a ros topic.
[link text](http://wiki.ros.org/rosserial_arduino/Tutorials)
My commands:
1.) roscore
separate terminal
2.) rosrun rosserial_python serial_node.py /dev/ttyACM0
which is my port.
After a few seconds the following error occurs: Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python wih groovy Arduino
If I do the same procedure with an Aruino Uno it works without problems.
Does someone know the the mistake could be?
Thanks
↧
