DragonOS FocalX Sending Text Messages Over the Air with HackRF (GnuRadio, HackRF-Minimodem-ImGui)

- In this video we'll be using two HackRF software defined radios and a new project called HackRF-Minimodem-ImGui. Leveraging the power of GNU Radio and Minimodem, messages and data from one computer are sent to another over the airwaves using HackRF.
The project, available on GitHub, provides a user-friendly GUI interface where you can input message content, baud rate, frequency, and more, making the transmission process remarkably intuitive.

To kick things off, I showcase the use of SigDigger alongside an RTL-SDR device on the same computer as one of the HackRFs. By visualizing the signal transmitted by the HackRF, viewers gain insight into its modulation scheme (likely FSK), setting the stage for the main demonstration.
As I initiate the transmission, SigDigger captures the signal w/ the RTL-SDR allowing you to hear the characteristic modem-like sounds as it decodes the incoming messages.
In the last part of the video, I present a dual-computer setup featuring two separate HackRFs, seamlessly exchanging messages back and forth over the air. It's a great display of SDR technology in action, highlighting the versatility and potential of HackRF coupled with GNU Radio and Minimodem.

🎉🎉 thankyou for review my app 🙏🙏🙏
Hopefully I got it right! I was trying to in the moment also remember signal analysis on SigDigger.
@@cemaxecuter7783 totally right.. wonderful explanation.. 😃
JUST discovered ur channel ur a genius
this is something i have been trying for a while but cannot get working the way i want, i am looking to make something to communicate with on a local level over a p2p bridge so the devices arent directly connected to the internet but rather a private 4g network or even 2g if need be i know there are things like openran and protocols like sip and ss7 but i haven't got it to work, now it has been a while since i tried and i noticed that openran has more documentation out since i tried any ideas on this?
Is there any chat we can join for more??
I want to learn about this and there are not many places to learn for sdr
So thats how you spies chit chat
Do you have a discord server or some place to discus topics about SDR?

@@cemaxecuter7783 thank you so much
@@cemaxecuter7783do you have a updated link?
Hello, This is great, Is there a way in can process this from the command line? e.g. Minimodem -from CS1 -to CS2 -freq 433000000 - BD 300 -text message here
If u want catch them hit me up can catch them in air, near power lines
Dragonos é você mesmo ? O que gravava sobre minecraft
nada a ver irmão
You mean do I make DragonOS? Yes. That’s me.
