Hi,

I just installed win_ros fuerte. I have been running electric on windows without any problems. A linux box acts as the Master and the windows machine broadcasts messages to the linux box. However, with win_ros fuerte I am unable to get my messages across to the linux box. Win_ros will run fine with the ROS_MASTER_URI set to the ip address of the linux machine. Also, when I start broadcasting messages from windows I can see the message name when I type "rostopic list" on both the windows and the linux sides. However, I can only echo the messages on the windows side. It seems like there is enough connectivity between the machines to see that a message started, but not enough to actually pass the data. The same thing happens when windows is the "master". Ros_wtf just gives an unknown network error.

I realize this is a vague question -- I'm mainly interested in knowing if anyone has successfully talked between windows and linux with win_ros fuerte.

Thanks! Mark

Looks like it is the usual multi-machine problem. If so, it's not directly related to winros, just make sure you get your ip/hostname settings exported correctly.

Seing as this question comes up often with windows-linux ros connections, I've added some information on the WinRoS FAQ. A direct link to the issue in detail is here.

I can confirm that I've successfully sent data from a windows computer to Linux using fuerte. I followed the instructions for setting up the SDK on Windows 7 and then built a ROS node using Visual Studio. I was able to send both data and video to a Linux computer over the network (with roscore running on the Linux box). Other than changing ROS_MASTER_URI, the only other thing I can remember that I did was to add entries to the hosts file on both the Windows and Linux computers (to make sure each computer had the correct IP address of the other).
