Unable to connect jetson nano board to my laptop with jetson function

We use Matlab 2021a and jetson nano board TX1. To connect the two we use both a usb and a network cabel.

At the beginning, we first met the problem and tried PuTTY and changed static network IP to connect the board and laptop successfully. But the connection status was automatically disconnected frequently before we run the next command. Now, we directly cannot connect the two anymore. The command window shows the error as the figure:

Because it has been successfully connected, the parameters in the jetson function, including the network IP, name, password should be correct. The PuTTY is also connected properly now.

We tried other versions of Matlab but still no use.

Can someone in Matlab, help me to solve this problem? Thank you in advance!

Hi Wentao,

Instead of static IP can you please put a link local only connection setting in the network manager. It will automatically configures the Jetson IP and makes both the laptop and the board in the same network. For the MATLAB to access the Jetson, it must always be in the network and no firewall should block the ports we use (18735 and 22).

Thanks,

Ramakrishna
