Hello,

I want to link my Arduino yun mini with a built-in wifi with my PC (on Ubuntu 14.04, ROS Indigo) over wifi and run the ROS-node on the Arduino with the following command :

rosrun rosserial_python serial_node.py tcp

or

rosrun rosserial_python serial_node.py _port:=tcp _baud:=57600

But when I launch that, [INFO] [WallTime: 1475872810.849287] ROS Serial Python Node Fork_server is: False [INFO] [WallTime: 1475872810.858924] Waiting for socket connections on port 11411 waiting for socket connection

I don't understand that error because when I link them using USB connection with network port selected as my access, I don't have any problem. I searched on Google but nothing solved this problem.

Thank you !

Thanks to @ahendrix, I managed to adapt its code for ESP8266 to connect as Ros serial client over WiFi. I supose you can adapt it to Arduino Yum, by creating the class WiFiHardware, that will create the method necesary to connect with: $ rosrun rosserial_python serial_node.py tcp

Please find a working demo code for ESP8266 (not Yum) at https://github.com/agnunez/espros that you will probably adapt with Yum includes, instead. Have fun, Agustin
