Maybe I’m missing something, but I haven’t found any way to get the bandwidth-test CLIENT to use ports other than 2000 if you need to set the server side to different ports. I’ve determined that changing the server settings on the client side doesn’t affect the client’s behavior, it just keeps trying to use 2000.
I went back to double check it, but when I connected the client to a non-standard port, it negotiated the port automatically. I was using ROS 6.46.4 and tried multiple ports. Each time, the client auto negotiated without any trouble.
