hydro rosserial_python with groovy Arduino error

Projects Programming

Hi Arduino Community helpers,

I'm running utunbu 16.04 and ROS, and I'm trying to get ROSSERIAL working (ROS communicating with Arduino Mega 2560) but failed in doing so,

it is on port ttyACM0 (Utunbu can see this serial port of Arduino Mega 2560 but I'm just unable to connect to it),

I ran roscore

and then I ran the below command:

rosrun rosserial_python serial_node.py _port:=/dev/ttyACM0 _baud:=9600

and I got the below error: (really not sure what that means and what to do to resolve it, however I can upload a sketch from the Arduino IDE with no issues, is just with the above line, I'm not able to make any connections...)

Unable to sync with device; possible link problem or link software version mismatch such as hydro rosserial_python with groovy Arduino

Attached screenshot,

Thank you and I look forward to your reply,

Roger

Is this a question about programming an Arduino or about a Python program running on a Linux system ?

This is a Python program running on a Linux system,

sorry if I posted in the wrong area, can you please let me know which area I should post this in?

thank you,

A Python forum would seem like a good place

do you have the link to the Python forum here?

I cannot see the Python forum in Aduino forum,

Thanks

That should come as no surprise. The purpose of this forum is to provide help and advice on Arduino and closely related devices, not on Python, and this section of the forum is dedicated to questions about programming those devices.

As it happens, some of the members here may also be well versed in Python and able to provide help but you would almost certainly be better to find a forum (not this one) dedicated to Python

thank you for your direction!
