sparrow-wifi VS urh

Repurposing WIFI and DVB-T receiver devices as SDR receivers works "OK", but trying to use a SDR for WIFI is terrible. There have been some attempts to analyze WIFI with the HackRF, but the narrow bandwidth/sample rate make it pretty useless. https://github.com/ghostop14/sparrow-wifi

with import {}; let pythonPackages = python3.pkgs; in stdenv.mkDerivation rec { name = "sparrow-wifi-env"; buildInputs = [ git pythonPackages.python pythonPackages.pip pythonPackages.virtualenv qt5.full gpsd ]; nativeBuildInputs = [ pkgs.stdenv.cc.cc.lib ]; shellHook = '' virtualenv venv source venv/bin/activate pip install QScintilla gps3 dronekit manuf python-dateutil numpy matplotlib git clone https://github.com/ghostop14/sparrow-wifi cd sparrow-wifi ''; }

Digging into this rabbit hole I found Sparrow-wifi has a spectrum display but it seems to want a separate Ubertooth or HackRF receiver.

I recently tried t run Sparrow WiFi ( https://github.com/ghostop14/sparrow-wifi ) but some python module returned an error which i couldn't figure out. Plz help to fix this.

>> or somewhat expensive and complex SDR

I don’t think that’s as accurate today as it used to be.

On the hardware side there are tons of options very cheaply available - iirc the flipper uses the c1100 (or a number like that) it’s a popular cheap chip and it’s well documented and interfaces easily with arduino.

More accessibly, lime mini SDRs are cheap but there’s quite a few alternatives too.

On the software side GNU Radio is free with decent tutorials - we’re not talking anything like blender levels of difficulty to adopt even if it is a complex domain.

Although on the more accessible side, urh is incredibly powerful given how easy to use it is https://github.com/jopohl/urh

I used the latter to tap into a 2 channel wireless bbq thermometer via a $10 rtl sdr and that was a breeze, an absolute walk in the park compared to when I reverse engineered the flysky telemetry system.

Universal Radio Hacker on Github

you should check out Universal Radio Hacker

Check out URH.

URH can read flipperzero sub files and can export from wav to sub... https://github.com/jopohl/urh

Throw the recording at UniversalRadioHacker and see what it does with it!

I dont have much knowledge on decoding a signal from scratch but try URH - universal radio hacker here. It might be able to do what you need.

It's useful for transmitting digital RF signals to control household stuff, eg. ceiling fans or whatever. You'd want to also look into rtl-sdr and Universal Radio Hacker.

Tried tool https://github.com/jopohl/urh and it does not get too much information. I am expecting to find something similar to wireshark - it can detect protocols in traffic and highligh different kind of fields in packet headers.
