I had a working Core2 program (connected with RPi), which subscribed two topics (cmd_vel and EmptyMessage) and publishes five topics (2 Int32, Range, BatteryState, and PoseStamped). When I try to add an additional Odometry message I get the following error:
wrong checksum for topic id and msg
which was repeated very often.
I tried to incease the input and output buffers for messages but that does not help. The error occurs also when the odom message is empty (just filled with IDs and time stamp).
