Gosu's profile - activity

uhm not really. As soos as I start the app, the nodes was not show up. Beside, I use startActivityForResult() to call other activity and wait for response, so I think the main activity was not shutdown. After the other activity finish, the main activity will show up again.

Hi, I want to modify the pubsub tutorial so the MainActivity call other Activity and wait for response. The problem is when I add startActivityForResult function, the 'talker' node and 'roxTextView' node dont show up in rxgraph. It seem NodeMainExecutor has some conflict with startActivityForResult().

Do you know how to fix it?

Thanks in advanced.

Thanks alot! Its worked

Thank you very much! Its worked! I forgot to set ROS_IP and ROS_MASTER_URI variables

I have tried but no luck, the rosTextView node still doesnt receive anything

Yes, both the node appear, but my talker node only publish to /rostopic.

Hi, I have installed the android_tutorial_pubsub on android device and able to connect to roscore on my computer (I see the chatter topic in the topic lists). I run a Talker node on my computer and see the data publish to the chatter topic correctly. However, the rosTextView node on my android device doesnt show anything.

Do you know how to publish data to a node on android device?

Thanks in advance.

Hi, I have installed the pubsub android tutorial on an android device and have it connect to an external roscore on ubuntu desktop.
When I run rostopic list on ubuntu desktop, the "chatter" topic is listed. But when I publish data on this topic, the rosTextView on android unchange. However, run rostopic echo /chatter display the data I published.

Would you know how to fix this?

Thanks in advance.

Thank you very much for your answer. I will give it a try.

Thanks in advance.

Hi,
I would like to remote control Lego NXT robot with android phone. I can do it with the robot and android phone both connect to a desktop with ROS installed. But is it posible to remote control with android phone and the robot only, something like Nxt Remote Control app on Google Play Store (sorry I dont have enough karma to post link).

Thanks in advance.

Sound sensor is not supported in ros, only sensors listed in http://www.ros.org/wiki/nxt_ros is supported
