Re: How to debug python blocks.

What I've *done* in the past, but I can't remember how pretty that was: GDB has python integration (essentially, a large gdb script + python debug infos). If you can break at a C++ function that your python work() calls, you should be able to e.g. py-bt into the mother frames etc. Cheers,

Hi Marcus, well, I try your way and I will report if I was successful, or not. Thank you for the hint about the new variable. Now, I go to bed and my computer compiles the new warm 3.9.0 from source :-) Thank you! Tom On 17.01.21 22:38, Marcus Müller wrote: yep! Seeing that you can install

Yah, there might be some kind of hack, but you're right ... since a Python block is being exec'd via a C++-to-Python gateway it's in a no man's land from the debugger perspective. On Sun, Jan 17, 2021 at 4:46 PM Nicholas Long wrote: > So I get the fact that GNURadio is highly parallel, that is

So I get the fact that GNURadio is highly parallel, that is fine. I debug C++ OOT blocks all the time and it is super easy, generally I make specific effort to isolate the OOT block that I am currently working on in a test flowgraph. For C++ OOT blocks I just run the python top_block.py in gdb

yep! Seeing that you can install these separately, you definitely are setting the PYTHONPATH environment variabl so that either version is found; do the same for GRC_BLOCKS_PATH, so that the two block libraries don't interfere, if you haven't already. Then: GNU Radio 3.9 respects a new

Hi JM - I agree.  And typically with knowing very little about anything,  one can jam WIFI using aircrack-ng. But I would argue the SDR doesn't have to handshake with the receiver or scan the network, so it may be more efficient. But on the other hand, you may need more computing power then

Hi all, I installed 3.8.2 and 3.9.0RC0 on my system (Debian 11 testing). Both instances are running well but I want to distinguish/separate the files which are opened when I start GRC. At the moment 3.8.2 is opening file a + b and when I start 3.9.0, the same files are opened. Instead of this I

Hi Paul - you need to post your grc file, version of gnuradio, version of gr-osmosdr and which operating system you're using. These people good - but they can't read your mind. And I would recommend using the word "transmit" instead of "jamming" - otherwise - judging from the number of

I mean really why don't you just google stuff lol and end it. Jamming is illegal, testing your network it's not so don't jam others and you are fine. Don't jam your router with high transmitting power stay as close to your router 1 meter so you don't affect others and and you are good to go.

Hi Jean, So the attacks against wireless systems are not only Jamming. Typically wireless attacks can be broadly categorized into 4 types (Jamming, Spoofing, Relaying, and PHY reversing). Yeah, you're right, the military does pay you for building these kinds of systems and this is rather an

We might hide or we might discuss ... jamming systems are less than 10 euros on amazon [0] for any script-kiddie to play with including myself [1]. Why anyone one would want to implement this in SDR rather than a NE555+VCO is beyond my understanding by why not ... we even got to reverse
