Cannot command forward velocities

[skohlbr]

Thanks for making this nice App, it's a quite comprehensive option (compared to others) for controlling ROS-enabled robots from a Android device.

I have a weird problem on my Nexus5: When I command a forward velocity, the linear x part of the Twist message stays at 0. I can command backward linear motion just fine, and rotating (z angular motion) also works. What also works is inverting x, in that case forward motion works, but not backwards. Any ideas what is happening here? This issue prevents me from really being able to use the App.

change the topics /joy/cmd_vel to your topic used .../cmd_vel (example: turtle1/cmd_vel)

As the app does not seem to be maintained at the moment, here is an app (from OSRF) that you can use as a workaround:
Map Nav
At least it works for me on a Turtlebot3 burger running Kinetic.
