hi guys,

I´m working in a project in which i have to run rviz in a tablet. I´m using ( ) app. But in the app i don't received any date.

i'm working with indigo and ubuntu 14.04. i'm trying the next steps:

1) i run my simulation in rviz in my pc to show if my program show something.

2) i run

3) i run tf_throttle that the app required.

and to finish i run the app of rviz on my tablet.

the app ask me for a ip. we try doing it by wifi connection. We make netstat to show if the connection is working or not and in the state it say is established but no dates are sending or receiving.

Proto Recv-Q Send-Q Local Address Foreign Address State


In the app in the status of a display that is working in the rviz of the pc say No PointCloud messages received.

what could i try to make the application work?

This could be a classic ROS-on-Android network configuration issue. See:

for some other questions about this.

In short: make sure that you either have a properly setup DNS (where both your Android device and your ROS master can resolve each other's hostnames), or force the ROS master to use bare IPs for everything, using appropriate values for ROS_IP and ROS_MASTER_URI.

But where i have to put that?

I have already done



i put it in .bashrc, but in the tablet i can do it by commands. The APP ask me at first the ros_master_uri i understand. So i put what i export in .bashrc and it doesn't work.

Please don't use answers to post comments. Use the add comment button for that.

Also: I said this could be a network issue. But in any case: I'd set ROS_IP to what you have now. On the tablet, you indeed use Can your tablet receive other msgs?

thanks very much! at least we could do it. It was our simulation problem, It wasn't any problem with the IP. Thanks a lot!
