sghctoma / antfs-poc-defcon24 Goto Github PK

Hi,

first of all thank you for your great work!!

I would love to get the project you created up and running.
I have set up an old Ubuntu 16.04 and provided it (with hopefully all) dependencies.
After loading your .pothos-file to PothosFlow it starts and this was the first point where I got problems.

Your two plugins (ShockBurstDecoder and ANT-FS Decoder) were not integrated correctly. PothosFlow displayed a corresponding error message when starting.

NOTE: You mentioned in your README to use clang to compile shockburst.c. I could compiled shockburst.c but I found no way to pass the compiled module to pothos.

So after a short research I added them as stated in the wiki of pothosware:

• https://github.com/pothosware/PothosCore/wiki/BlocksCodingGuide#block-desciptions

Chapter Building and installing:

mkdir my_build_directory
cd my_build_directory
cmake path_to_source_directory (e.g. /opt/antfs-poc-defcon24/sniff/pothos/ANTFSDecoder/)
make
sudo make install

For this I had to remove a parameter ( -stdlib=libc++) inside the CMakeLists.txt located in the source_directory (/opt/antfs-poc-defcon24/sniff/pothos/ANTFSDecoder/) .
After that both modules compiled and were successfully added to the pluginregister. I checked this with "PothosUtil --module-info".
Now the modules were loaded when starting PothosFlow.

NOTE: There is one error listed in the message-Window when loading pothosFlow : [15:27:50.122000] ::1: usb_claim_interface error -6 Do you use any special driver for the rtl-sdr? I didnt find anything regarding that error...
So now I would like to start sniffing the ANT network traffic.
But at this point there is still a problem, I cant see network packets (I get only the message output from the picture I uploaded). Should not there be more information like in your defcon talk?
For generating some kind of network-packets I have connected a ANT-USB stick to the ANT-FS PC client (Dynastream Tool) which should send a beacon as a client. (I tried sending data as a host as well) I cant see anything from that tool or it is not showed properly in the message-output.

Does your module work as it should work?

Can you help me at this point?
I want to use this as my topic for my Bachelor Thesis which should be ready to the end of the next month. If you need more information I will be happy to give it to you...

Cheerz

PS:
This is the message-Window when starting pothos-Flow:
Could there also be a driver issue with the RTL-SDR itself?
