Unable to establish ethernet communication with Jetson Nano and ClearCore controller

Hi,

I’m seeking some advice on an issue we’re encountering with establishing Ethernet communication between a Jetson Nano (IP: 192.168.1.134) and a ClearCore controller (IP: 192.168.1.100). When we attempt to ping the ClearCore controller from the Jetson Nano, we consistently receive a “destination host unreachable” error.

To troubleshoot, we connected the Jetson Nano’s Ethernet port directly to our laptop (IP: 192.168.1.25). Pinging from the Jetson Nano to the laptop also failed. However, when pinging from the laptop to the Jetson Nano, we received a reply.

I am not sure what is the setting of ClearCore controller.

If you connect port to port between Jetson nano and other computer and set static IP, will it work?

Does it work when you use a small Ethernet switch instead of a direct connection?

Thank you, @WayneWWW and @fchkjwlsq, for the response.

On the ClearCore controller side, we have set the IP address to 192.168.1.100, and the server IP address (Jetson Nano) is 192.168.1.134. We also configured the port number as 8888 for packet transmission and reception.

The issue we were facing was resolved after adding a new inbound rule with the port number in the Windows Defender Firewall settings. Now, we can successfully ping from both sides.

However, when we run the code on the server (Jetson Nano) and ClearCore controller, the Wi-Fi connection intermittently disconnects until we end the node. This affects our NoMachine connection with the Jetson Nano.
