Hi !
I'm looking from a package to communicate btw arduino and ROS kinetic (on jetson) with an arduino ethernet module.
I need to send msg / srv from arduino to the jetson.

Update:
I found a file ArduinoTcpHardware.h in the rosserial github. Anyone know how to use it ?
So finally I found a solution.
I use this example from the rosserial github.
To run the ros node use roslaunch rosserial_server socket.launch.
For IPAddress ip(192, 168, 0, 177); choose an IP for the arduino.
For IPAddress server(192,168,0,11); use your ip.
It looks like there are two examples for using rosserial over TCP. If you have rosserial installed and the Arduino library generated and installed, you should be able to find these from the Examples menu in the Arduino IDE.
Yes I can use these example but when I try to compile with catkin build I have this error
CMakeFiles/ethernet.dir/tools/ethernet/main.cpp.obj: In function `loop':/home/.../main.cpp:74: undefined reference to `ros::normalizeSecNSec(...)
I can compile some others ros example with catkin build
Unfortunately I don't know of any ready made solution for you to get this working. The rosserial library works with arduino but only over a serial link. I don't think arduinos are capable of running a full networked ROS node.
You may have to look at building a ROS independent link using a protocol such as UDP. This would link via ethernet back to a full ROS node on the jetson which would provide the gateway to ROS.
Hope this helps.
