2019-12-03 03:04:20 -0500 | marked best answer | Rosbridge Server gives warning when I try to unadvertise or unsubscribe Hi there, I have a ROS Kinetic running Raspberry Pi 3 B (I have installed ros as a ROSberry installation, from the source as suggested), which runs Rosbridge Udp Server over it. I am getting in contact with it via a Windows-10 Laptop which has a c++ program running to send JSON's to the Raspberry Pi. When I send advertisement or subscription requests system runs perfectly, I am able to publish/receive messages and create topics easily. After I am done with the messaging, I want to unadvertise a topic (and unsubscribe) so that topic will be killed by ROS Master since there will be no subscribers or publishers left. I am sending the following JSON's to unsubscribe and unadvertise:
then I get the following warning, which says (I believe) I am asking ROS to unadvertise or unsubscribe, but I specifically added ID parts to the JSON's just to make sure that ROS understand the request is coming me and I am asking ROS to make me unadvertise and unsubscribe. Why am I having the warning and how can I fix this?

2019-07-25 07:10:38 -0500 | marked best answer | cannot install/run rosbridge on raspberry pi 3 I have a Raspberry Pi 3B which has debian stretch OS and a ROS kinetic running on it. I have tried to install rosbridge_suite and rosbridge_server on it from source as with this code and I had the following error: I believe rosbridge for ROS kinetic is already available, correct me if I am mistaken. After this failed trial, I tried to build it using a rosinstall_generator as described in here , by those commands: then I enter this: After doing this and catkin making, when I ask for rospack list to see the downloaded/built packages, I cannot see rosbridge server or rosbridge suite. Anway, afterwards I tried to run a node for rosbridge : and I got the error: Afterwards, I went to the folder in which launch file is located, and tried to run it with: As you can see I cannot run the node , and I am not sure what is the reason. Thank you for your help! |
