Hi,

I want to record a rosbag using ssh command. I use an Ethernet cable to establish the connection between my laptop and Nvidia Jetson placed on the robot. I would like to keep the Ethernet connection while unplugging the cable. Is it possible?

The rosbag record freezes after few seconds (no topics are published). I think it's due to the changed IP address in the network after unplugging the Ethernet cable. Is there a way to keep the IP addresses or an alternative solution to fix this problem?

Thank you in advance!

You have two questions:

Q 1. I would like to keep the Ethernet connection while unplugging the cable. Is it possible?

I didn't understand what do you want. How can you keep a connection after unplugging the cable? you are talking about Ethernet cable right?

Q 2. Is there a way to keep the IP addresses or an alternative solution to fix this problem?

Yes there is but dependent on clarification of question 1.
