Hi, I'm trying to add some self_test to my code but I'm having an issue: when I try to call the self_test service, it just hangs. I tried this on the selftest_example in the self_test node: > rosrun self_test run_selftest /my_node/self_test Failed to call service. The /my_node/self_test is there though: > rosservice info /my_node/self_test Node: /my_node URI: rosrpc://10.1.1.234:33971 Type: diagnostic_msgs/SelfTest Args: Any ideas?
