[Discuss-gnuradio] Alternating packet transmissions on 2 two different frequency bands
Hello, I currently have N210 devices with GNU Radio 3.7.0 installed. I am currently using them to send and receive packets between them through a tun/tap interface. i would like to be able to send different packets (e.g depending on the MAC address for instance) on different frequencies. For example : - Packet to 01:02:03:04:05:01 send on f1 - Packet to 01:02:03:04:05:02 send on f2 I am currently wondering what would be the best approach to send a given packet on a given frequency. If I set a new frequency right before/after the send() call in the python script, I can't know if there are other packets in the buffers or if the retuning will occur during the transmission of the packet.

This looks like VOLK issue. Try removing ORC and recompiling since it's failing in VOLK on an ORC test. Also, why are you running a 32-bit OS on that processor? Seems a huge waste.

Hey guys, and thanks again for testing this. I ran some tests today and was able to reproduce this problem. However, to make it happen, you have to severely screw up the OFDM signal at the transmit side. The preamble detector (which is pretty robust) will still detect packets, and then flood the header/payload demuxer with guaranteed garbage. Eventually, even the 8-Bit CRC fails, after rejecting lots of packets. At this point, the HPD *should* catch the problem, but doesn't, which causes the block_executor to throw a runtime_error. I'm not sure where the bug is, but there definitely is one. I've opened http://gnuradio.org/redmine/issues/611 and will try and figure this out.

Re: [Discuss-gnuradio] GnuradioConfig.cmake not working properly ?
Hi Tom,
I'm afraid my patch broke something :( gr-osmosdr and probably some
other OOT projects that were using GnuradioConfig but without using
the _ALL_ variable but using the individual ones.
Turns out that after the patch, GNURADIO_XXX_LIBRARIES is no longer
directly build from find_library, but from a custom foreach loop (to
build up the proper list)
But that also mean that it's scope is not restricted to the function
and is not global and so not available elsewhere.
The attached patch fixes that by re-declaring the variable in the parent scope.
This fixes the gr-osmosdr build for me.
@Martin : could you give it a shot to check it fixes it for you too ?
Cheers,
Sylvain

[Discuss-gnuradio] Question about working with multiples of input values
Dear GNU Radio, I am writing a GNU Radio block that processes the input in blocks of 1024. Is there a way for me to tell the scheduler that I can only accept inputs in multiples of 1024, or do I need to block the input, and save the left-overs for the next work() call? If the latter, how do I know if the work() call is called for the last time?

Re: [Discuss-gnuradio] GNU Radio LiveDVD 2013-1110 (based on 3.7.2)
Sadly Dream appears to be an "open source" implementation of a protocol
that is licensed and has no rights allowing for a decoder. While you
may choose to use it, sadly, distributing it on a livecd would be very
unintelligent as it would make the distributor legally liable for
breaching the license most likely.

Re: [Discuss-gnuradio] GNU Radio LiveDVD 2013-1110 (based on 3.7.2)
Hi Zero,
You're wrong.
Dream can be distributed as it's GPL licensed. All the code is GPL, except
concerning the AAC codec (FAAC and FAAD2), but you don't need to distribute it
together with dream, as it dlopen()'s the AAC library dinamically (so you can
install AAC "live"). Most windows and linux dream distributions just do not
place the AAC together, and recommend you to just install it separatelly (from
rarewares or a simple script that downloads the source and compile it).
Also, for the purpose of lab testing, modulation/demodulation, I don't even use
the AAC codec, as it also comes with the great Opus codec, which is much better
than the FAAC AAC LC encoder.
Best regards,
Rafael Diniz

I'm certainly not perfect but if you bother to look at Dream's website:
http://sourceforge.net/apps/mediawiki/drm/index.php?title=Main_Page
You will notice they say these words, all in red, on a line by themselves:
"Although this software is distributed as free software under the terms
of the GPL this does not mean that its use is free of rights of others.
The use may infringe third party IP and thus may not be legal in some
countries."
I would strongly discourage anyone from distributing code that is
violating someone else's IP. The code is gpl, that's great, but since
it is violating (if I had to guess a US patent) IP knowingly, it puts
anyone distributing it at risk. I know I for one won't be distributing
such code with my livecd which contains GnuRadio. Obviously anyone else
can do what they think is best.
Amazing what you notice when you read something...
