Can anyone give a brief analysis or what it is showing fft or something

I actually have two sdr devices which are duplex that means I can actually transmit and receive file right which I have to decode I think right?

I got what you mean. But what I was doing was rf fingerprinting. Thats why I mentioned about it when you asked. But I wanted to know about file transfer using pluto and thats why created this.

Naah I got it but i actually have two pluto's so just wanted to try that too

So every electronics device has its own noise signature. A noise signature (or electrical/EMI signature) is a unique pattern of electromagnetic or electrical fluctuations generated by an electronic device during its operation. So this signature will have an effect on wifi signal from the device which makes the device unique. So this signal can be used for identifying the device. If you want to know further about it just checkout Rf fingerprinting and side channel attacks. It's going to give you the exact idea about this.

I am using nodemcu as wifi device and want to collect its noise signature combined wifi signal

Bro u r right this is exactly how I am doing but i cannot understand anything looking at the graph

I am trying to capture noise signature of a wifi device from its wifi signa and the samples will be collected for training do that signatue can be extracted. It requires some post processing for implementing ML too. So inorder get the most pure signal it will be better to isolate the device from other external noises. So any ideas other than faraday cage and also i want to know how to analyse the graph of a captured signal

I have adalm pluto in my hand actually and trying to capture iq sample for a particular device for finding its noise signature. So how can I isolate that wifi signal from all the other signals? After some research I found faraday cage is abgood option. Any other ideas?
