Another problem I ran into today:
When sending messages from an Android app (e.g. Turtlebot teleop sending
geometry_msgs/Twist), the callback of my roscpp subscriber didn't get
triggered.
I tested this with simple subscriber implementations in roscpp and rospy in
parallel (plus rostopic echo, which is also implemented with rospy AFAIK).
This only happened when sending from Android, so might be a bug there (or
just because we currently can't recompile those apps). When sending from
another 2.Beta Groovy 64Bit Ubuntu machine, callbacks in both
implementations worked fine.
If anybody knows further tests, with which I could narrow down the root
cause, please let me know!
Thanks,
Marcus
