This node automatically spins up subscribers and publishers based on the . After increasing the delay to 50 milliseconds it seems to work better which means it does not stop after ~1000 msgs but after ~10000. Here you will learn how to convert list to string with whitespace in python. . The rosserial_python package contains a Python implementation of the host-side rosserial connection. Therefore, the deserialization function will automatically allocate enough storage using realloc(), attempting to reuse the memory location whenever possible and only expanding it when the new message received is larger than the largest previous message. So maybe the problem is in the communication between Core2 and RPi. Arrays have similar limitations to strings, however, since there is no easy way to find the termination of an array (analogous to the \0 found at the end of a string), we need to specify the size of the array. The only modifications are mentioned above. . You can use ros-core2-client with roslaunch, but it requires a bit of workaround.
