Hey all,
I'm trying to turn the wifi receiver flowgraph in this repo (
https://github.com/bastibl/gr-ieee802-11/blob/maint-3.8/examples/wifi_rx.grc)
into one that will work with the HackRF.
The example uses a USRP source, with a normalized gain of .75. I'm not sure
how to translate that into para
Hi Daniel,
please remember to be specific when asking a question: "best way" is a
bit ambiguous, and "I'm not getting a good result" definitely is
insufficient for us to help you make things work better. What doesn't
work sufficiently well? What happens instead?
Best regards,

Hi to everyone.
What is the best way to receive all fm modifications. I'm usigin an B200
USRP.
I think that putting the center frequency at 98M and a bandwidth of 20M is
a good way,but I'm not getting a good result.
The idea is to detect all fm center frequencies using gr-inspector

Hi Daniel,
no, that's not right.
In your program, whatever that is, if it wants to use GNU Radio:
You set up a bunch of blocks – to even instantiate them, their
constructors must return – and then tell the GNU Radio top_block to
connect them. After you've done with that, you tell the top_block
Ok. Thank you.
I managed to get the messages from the debug block. Now, I have to deal
with types conversation.
Thanks

Hello to everyone.
Could somebody explain me what is the life cycle of a gnuradio program? I
understand that all the action occurs in the constructor of the main class.
Am I right?

Hi Sara,
stock GNU Radio indeed doesn't include any VITA49 I/O capabilities.
I'm not aware of any GNU Radio out-of-tree module that you could use to
gain that.
I know that Josh Blum wrote a VITA49 serializer for GREX, but that's
not compatible with GNU Radio. It might serve you as inspiration fo

Hi,
a full agreement from my side: especially when using Ubuntu 19.04, you
get a pretty recent GNU Radio. If you want to talk to your hackRF, you
need gr-osmosdr, too, so
sudo apt install gnuradio gr-osmosdr
and the thing is set up.
Best regards,
Marcus

Hi geraldfenkell -
On modern Ubuntu, you should be able to just issue "sudo apt install gnuradio"
and after some ado GNU Radio will be installed. See also <
https://wiki.gnuradio.org/index.php/InstallingGR#Linux >.
The HackRF software interface should be pretty easily installable on Ubuntu (or

Hi. Thanks for your reply.
The signal extractor block's output is a vector of tuples with center
frequency an band width. I want to know the length of the vector without
using the debug block. And store the data for further processing.

Yeah, char signedness is compiler-dependent (and can be configured with
-f[un]signed-char in GCC). Neither C nor C++ specify a "default"
signedness in the standard.
So, if you want to do arithmetic on chars, you need to specify which
data type you'd want – signed char or unsigned char.
That's wha
