Unable to connect LINX to RaspberryPi

[Freshi]

Hey everyone,

I'm having a major issue connecting LabVIEW and LINX to my Raspberry Pi 4B. Here's my setup and the problem I'm facing:

Setup:

• Raspberry Pi: Raspberry Pi 4B running Raspberry Pi OS (64-bit).

• Hostname: raspi

• Username: pi

• Password: rasberry (default configuration).

• The Raspberry Pi is fully updated.

• I enabled the systemd-networkd service and assigned a static Ethernet IP address in the same network and subnet as my laptop.

• I'm using NI LabVIEW 2025 Q1 Professional

Current Status:

• My laptop can find the Raspberry Pi in the ARP table.

• I can successfully connect to the Raspberry Pi using SSH.

• The network connection between my laptop and the Raspberry Pi is working.

Problem:

When I try to connect LabVIEW via LINX Target Configuration to the Raspberry Pi, the connection fails with the following error:

Device interrogation failed: Unable to connect to the target.

Using Wireshark, I noticed some issues during the SSH connection setup.

Additional Information:

• I have attached screenshots from Wireshark and the error message from LabVIEW for further analysis.

I'm out of ideas on how to fix this issue. Any help or suggestions would be greatly appreciated!

Thanks in advance!

Hello! Did you manage to solve the problem?

Hi,
The target configuration utility requires the Raspberry Pi 4B to be running the 32 bit version of PI OS.  The Raspberry Pi requires Internet access to download the required packages.

It's best to enter the IP address of the Raspberry Pi in the target configuration utility. 

Are you using link local IP addresses for your laptop and RPi? Does the RPi have a route to the Internet?

The installation process can take a few minutes. Do not try to restart the installation by clicking the connect or install buttons on the GUI!
