Send data to Jetson TX2 using TCP/IP

Hi,

I want to send data from Simulink on my laptop to my Jetson TX2 board using the TCP/IP blocks available in the GPU Coder Support Package for NVIDIA GPUs. In this case I want the laptop to act as the client and the TX2 as the server where I will be running a Python script to receive the data and perform calculation on it. The laptop and Jetson board are connected using an ethernet cable and a Link-Local connection is created between them. However, I cannot get the TCP connection to be accepted by the server and therefore no data is being sent.

So far I have:

• Set up the connection using the TCP blocks from Instument Control Toolbox. However, using these it is not possible for me to run my simulations in real time.
• Checked that the connection is working by pinging both the laptop and the TX2.
• Made sure my firewall is disabled.

Any insight into how I can solve my problem is much appreciated.

Thanks!

Matilda

Hi Matilda,

I understand that you are using 'TCP/IP Send' block to send data from simulink to Jetson TX2 board. The connection is established and working fine. But, the data is not received at the server.

Could you have a look at the procedure mentioned in the following link and see if it works for your case?

Hi Matilda,

Are you using the correct port to request for connection at the server?

Did you solve this problem? I encoutred with same problem like you. Probably, ı can not configure ip adress and port. Now, ı can send ping to jetson. However, ı cant send data to jetson with ethernet. I didnt understand what is my problem.
