Hello gao,

Yes, I can understand that but, on your computer, it would be storing a file as well. What is the size of that file?

I use DCA1000 default config without mmWave studio and store data by wireshark, so the file haven't any value.

Hello Gao,

Can you first just use the mmwave studio with the AWR2944 and capture it using the studio instead of wireshark?
That will help us identify where the issue is.
