You want a vector to stream (not to "stream*s*") block.
The reality is that what OFDM block diagrams typically show as
"parallel to serial" block is usually not actually there in software or
hardware architecture. Authors just put these in there to say "hey,

Hi Daniel,
please remember to be specific when asking a question: "best way" is a

no, that's not right.
In your program, whatever that is, if it wants to use GNU Radio:

constructors must return – and then tell the GNU Radio top_block to

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
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.

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.

I'd love this, especially if we end up with a kernel that we can use to
build decimating FIR filters that inherently convert to higher-bitwidth
int or floating point.
I think this could be super useful in hardware flow graphs, where one
would get integer numbers from hardware anyway;

Seems you didn't quite install things into a place CMake looks into by
default; quite possibly, there will be needs to tell CMake about
/usr/local/include/volk (which is what I guess is the default
installation prefix if you build from source manually).
Anyway, this wouldn't have helped you!

Hi Sebastian,
I must admit that I don't remember whether the TSB block base was
correctly wrapped for Python (darn it, first I write something, and
then you find a glaring counterexample); in fact, there's not a single
test case for that in the main GNU Radio tree, which probably means
"no".
I'm sure Team Platypus is awesome and will do the FOSS thing and
contribute that block to gr-eventstream?

Hi Sebastian,
classic one!
You send the messages in the block's constructor in an endless loop.
So, that constructor never finishes.
Thus, the block never can get message-connected. Thus, your messages
disappear.
You can't publish message in a constructor. Spawn off a thread in the
`start()`
So, you lose one packet; that might be due to synchronization having to
lock, or due to simulated or real-world noise.

Hi Aaron,

for the UHD mailing list.

Also: The version match between the volk you're using and the GNU Radio
you're trying to build is pretty close, so chances are a packaged VOLK
wouldn't help you build an arbitrary GNU Radio version :(
Furthermore, VOLK is dependency-wise like GNU Radio light: if you can't

Hi PCZZS,
I'm a bit surprised, this document still attracts so much attention.

Hi Johannes,
I've agreed with Bowen that for the time being, he'll be developing an

today, the student application period for GSoC 19 begins. I'm really happy that
we already have a lot of GSoC-related activity on this mailing list and I'm
looking forward to reading all those proposals!
Make sure you apply until April 9, which is usually a strictly enforced
Hi Johannes!
let me answer in-text real quick:

Removal of Ctrlport and the tools
Hello Tarek,
https://wiki.gnuradio.org/index.php/GSoC has information on all this.
You're relatively late to the game!
Best regards,

I'd recommend streams-to-vector and a matrix multiplier block.

Hello Faisal,
I pointed this out before: We're volunteers here. If you want us to
help you, please at the very least write emails with meaningful subject
lines. I personally consider that non-negotiable email etiquette.
Best regards,

Nice hearing from you :)
Have you met Travis? His gr-dpd[1], especially?
Cheers,

I don't intimately know the BladeRF driver, but it seems unlikely that
the USRP is way more computationally intense than the BladeRF. Chances
are the BladeRF driver doesn't /show/ the same errors.
Be a bit careful about saving away the data: your storage must be up to
supporting the constant data
Knowing the code, zooming in shouldn't really increase the
computational load significantly; a higher FFT length would do that!

Hi Parvathi!

i.e. 2.03dB, -8.83dB.
Displaying the frequency (x-axis) in dB is most definitely a bug. Which
version of GNU Radio are you using (`gnuradio-config-info --version`
has the answer)? We've fixed that a while ago.
Hi Rajpreet,
though it shares many characteristics of one, GSoC is not an
internship.
I'd recommend reading our GSoC Student info page[1] and the Google
Summer of Code FAQ [2]:

AFAIK only the things linked to in my last replies to you – which
actually are pretty comprehensive, IMHO.

Hi Faisal,
The link that Kyeong Su Shin shared actually *directly* leads to
scripts that can read the output of file sink.

You'd need to write your own block that can handle these formats.
A word of warning: When doing SDR, you deal with MEGASAMPLES per
second.
A 32 bit floating point number has circa 9 significant digits.
That makes 10 characters when you include the decimal dot.
Then you also need to write down
Hi Aaron,
must admit, I haven't tried it.
Technically, modtool depends on very little more than Python to do its
thing.
But then again, its thing is using sane compiler environments to build
stuff (you can't use any of the Linux or Mac package managers as
sources, obviously). And while that
Wait, are you doing this on ARM?
