Hello,
I currently have a B200 USRP that is supposed to transmit/receive a file
after being triggered by a PPS signal. The current file is able to to do
this if the PPS signal generator (I am using an FPGA for this and it is
accurate enough for my needs) is already on and transmitting the signal

Hi Lefteris,
I already got the same error.
I think, you must try to rebuild your OOT module as follow :
- cd gr-howto
- sudo rm -R build
- mkdir build
- cd build
- cmake ../
- make
- sudo make install
- sudo ldconfig
Cheers,
Marius

his can be possible because when I use tx_sob and
tx_eob, I can't be in RX and TX mode in same time.
I use a N210 USRP with a WBX daugtherboard.

I read some discusses about this error, but I can't understand why I get it.

I run *make test*, and all test passed.
If someone could help me to figure this out, It would be very he

I have checked all my blocks. All memory allocations are freed, and all my

So, how the memory can increase if I do not allocate extra memory and free
all memory?
Thanks you in advance.

that does that with GRC block? I know that
transmit_path.py or benchmark_tx.py do that, but they are not

right before modulation, mostly to avoid blocks
wasting performance on iterating over noise. I'm aware that a Squelch
Filter might archive a similar effect, but that still means the other
Signal Block go into general_work() routines.
So, why is carrier_sense() not in gr_sync_block etc.?

. The only thing I practically
need is to map the demodulated bits into frames (of variable length).
I don't think a full blown packet stack should be necessary or a queue
data structure.
I'd be happy if someone had a fix or a workaround. I'm not sure
whether there is a simpler solut
ooking for what the current chains exactly are: is there some
sort of flow-graph here. Did somebody already analyse this?
There are some custom FPGA builds here and there. I'd be happy if
someone contributed insights how to touch this without having to redo
everything.

I hope it doesn't add any latency to the equation like: RPC command +
UHD command + FPGA reaction + RF frontend. I'm not even sure if using
the C++ API would be any different. So my Monday
illoscope copes with that).
Here I use the WBX. My overall goal is to understand more about the
hardware.
So if someone knows how I can implement a callback or a polling function
to make the device tune for real, but as fast as possible, that'd be
very helpful.

Do you use the Function Probe block in GRC? Or is there any other way to
make it tune without ending the Flow-Graph?

While it seems the current build system is going to change to cmake...
is there any progress here that could ease my part? Or does anyone have

I think there's too much to do left, however I don't find a way to
treat this error.
If that works I'll do GRC integration and clean up the OpenGL stuff
(the code is from the source mentioned in the repository, but GPL).

Loading the released binary images did not solve my problem. I tried them all.
The problem persists in the same way I described it.

ere a newer/working version of any TX implementation on a
802.15.4 stack? I'm not sure how to patch or debug this issue, because
running through the Swig layer interface stuff with gdb is kind of
complex. So I was wondering whether I'm the first person ever facing
these bugs
able to
automatically detect the start and end point of a high-amplitude that
represents sending activity? I tried to use the integrator to lower
the amplitude (I'm not interested in demodulation at this point, just
tx start and end). But that doesn't work very well.
I hope my t

for me in order to know the data representation and to interpret the
results.
