Hi Johannes, I'm back at work after the new year break and have had a chance to try this again, and I think I have it working !! The problem was with my test waveform, I've captured a new test waveform and I can now sync to the DL signal and decode the MIB. Mike On 21 December 2013 04:26, Joha

Hi Ralph, I had the same problem at first myself, there is no need to reconnect anything in the top_level.grc block so long as all the hier blocks have actually been compiled. In my case the biggest problem was the LTE_estimator_hier block would not compile because the 'import lte' failed (see ear

Hi Johannes, I gave this a try today so I thought I'd pass on my results:- Firstly, I found that I could not 'import lte' as sync_cc.py could not import 'window' from gnuradio. I 'fixed' that by changing sync_cc.py as follows:- self.pfft = fft.fft_vcc(fftl, True, window.rectangular(fftl), False,

Hi Sylvain, I had a chance to try it 'for real' this afternoon displaying live signals from a BladeRF source. Let me just say WOW that's seriously impressive ! On my PC gr-fosphor handled the full 28MHz BladeRF BW beautifully. I've used R&S's FSVR and dare I say it, I reckon gr-phosphor is

Hi Sylvain, Nice work, I just gave it a spin here are my results;- I hit the 'clCreateFromGLTexture' issue when compiling the benchmark tool, not only did I need to comment out the #define but I also needed to turn off -Werror in the makefile. I get 61msps with a GT9800 on a i7-950 @ 3.06G Inter

Hi Philip, As Marcus and Tom have noted the SetUpdateTime() method can be used to set the display update time (but not the FFT calculation rate, which I think is what you want). As this method is a slot it is possible to call it from your application without any mods to the QT Gui sink, here's a

Hi Achilleas, I've been doing some work on the qtgui module. When I started this work I was using a somewhat hackish approach to building it 'out of tree', this weekend I've been working on cleaning this up so that the build is based on the process used in how-to-write-a-block from 'next'. In the

Hi All, Just a quick update to say I've got the QT Signals part working (I can double click the FrequencyDisplayPlot and catch a signal in my python app with the frequency and amplitude at which I clicked). It turns out to be trivially easy. My code is very prototype-y at the moment, I'll tidy i

Hi All, I've been playing around with gr_qtgui and adding a few 'enhancements' to suit my application, in doing so I've come to a bit of sticking point and I'm looking for some advice on how to proceed, my QT and SWIG experience are limited so I'm wary of doing things 'the hard way' unnecessarily.
