Kinova Gen3 (firmware 2.5.2) gripper stops any movement initiated by send_gripper_command service call if publishing to /my_gen3/in/joint_velocity topic. Depending on the publishing rate the gripper might start some motion: almost closes on rate 1Hz, twitches a bit on >10Hz.
Version
ROS distribution :
Branch and commit you are using : noetic-devel 085b694
On another Kinova Gen3 (older) which runs 2.3.0 firmware the behavior is as expected. Publish to the topic does not have any effect on the gripper service call. I have tested with both arms, same ros_kortex, just changed the IP in the terminal.
Any other information
Kinova Gen3 (older) firmware 2.3.0 - works as expected.
Kinova Gen3 (purchased Summer 2023) firmware 2.4.0 - 2.5.2 does not work.
Maybe it is related to the ros_kortex version? It seems to work on my colleagues PC, I think he uses older ros_kortex version, but then it shouldn't work with the older Kinova too in my system.

We will test this and report the bug to our engineering department if we can replicate it. However, looking at the source code of firmware 2.5.2, there are no changes in the communication layer, so in theory there should be no impact. Is there a change the act of updating your firmware solved the issue? If you re-updated to 2.5.2 does the issue reappear?
I don't believe the act of reuplading the firmware solved it, because the robot came with 2.4.0 originally and I have noticed this issue, so I updated to 2.5.2, but the issue still existed, hence I moved to 2.3.0 which our other Kinova Gen3 is running and it doesn't have the issue and it was fixed.
I can give a try and update the other Kinova from 2.3.0 to 2.5.2 to see if it might be the new arms' issue.
