Setup Hokuyo UST 10LX ip with remote access

edit

Hi, I am setting up Hokuyo UST 10LX on my Jetson TX2, but got confused about the ROS/Hokuyo/TX2 ip addresses. Hope you can help me clarify it.

Hokuyo ip address is factory default: 192.168.0.10 and it is linked to the Ethernet port of the TX2. I followed the instructions in this https://www.jetsonhacks.com/2018/02/2... and set my TX2 eth0 to 192.168.0.15.

However, my jetson uses WIFI and its ip address for wlan0 is 192.168.0.28. Since my TX2 is attached to a robot, I want to open rviz on another computer so I can monitor the data from the TX2. The other computer is also on WIFI and its ip address is 192.168.0.29.

My questions is what the ROS_MASTER_URI and ROS_IP on my TX2 should be?

Thank you very much.
