I have a RTI CONNEXT installation on my machine. Now whenever I run a node in ROS2, e.g. talker.py, I always get a runtime error : [RTPS_HISTORY Error] Change payload size of 'n'>5000 bytes is larger than the history payload size of '5000' bytes and cannot be resized. ->function add_change
I have already consulted this documentation but could not get the solution for it.
Any ideas ?
This can happen when using Fast-RTPS and Connext with a message in a particular size range. Long term rmw_fastrtps_cpp should be updated to use this enhancement . In the short term there are a couple options
rmw_connext_cpp for the ROS2 rmw implementation by setting the environment variable RMW_IMPLEMENTATION, orrmw_connext_cpp disables TypeCode to avoid this (see this issue ). I know this thread is old -- buy any tips for solving this problem in the context of MicroROS (using the Arduino library)?
I'm trying to use a custom message type containing a string and a float32, and it was actually working fine for me (I was able to echo MicroROS topic via agent), but something must have happened because now when I try to echo the topic I am seeing:
2022-09-13 20:48:29.787 [RTPS_READER_HISTORY Error] Change payload size of '16' bytes is larger than the history payload size of '11' bytes and cannot be resized. -> Function can_change_be_added_nts
Not quite sure where to go from here...
