Any update on this issue?

Tom,

Hi,
I wrote a custom block to compute beamforming weights. The block takes 8
inputs and 8 outputs.
It takes 64 samples from each input stream and produces 1 output in each
output stream.I am not getting any output and GRC stops working when I set
the decimation rate to 64.I tried printing noutput_i

Hi Manu,
This is exactly what I m looking for, you solved my problem thank you so
much.

I have a situation in which I need to read tags associated with multiple block
inputs in order to decide which input to process during general_work. In my
situation it's possible for there to be zero input available to some inputs,
and a nonzero amount of input available to others. The Catch-22
Try to print the samples received. Check if after some moment the samples
start to repeat.
I had some problems with that when I implemented my energy and waveform
detection blocks (based on the title you used in the post, probably you know
what they are). After some debugging, I figured that that

Hi,
I am not sure I understand your problem exactly. Are you defining the
variable as
firdes.root_raised_cosine(nfilts, nfilts, 1.0/float(sps), 0.35,
11*sps*nfilts)
??
There is a zip file containing all these examples. I assume you already
have them.
If not, you can find them in the link below.
Hi Martin,
Thanks for your answer, actionnally I don't have a code yet because I am
trying to run simulation from the flowgraph directly. The problem is in the
polyphase clock sync, in this block i should define several parameters even
the filter taps. Normally, I should add coefficients values or
I don't think there is any AGC on USRP hardware...

Hi Dan,
You are correct; I stand corrected. The XVCR2450 does not have an AGC.

Hi,
Following this website:

I've applied the patch mentioned and could run airprobe with gnuradio
3.7. However, I couldn't decode the example file nor live signals using
RTL-SDR. When I run:
./go.sh capture_
I don't think there is any AGC on USRP hardware...
Very Respectfully,

Please answer to the list.
