Re: [Discuss-gnuradio] Help: Display Freezes

Re: [Discuss-gnuradio] Streaming Funcube Dongle Pro+ over UDP

Hi Vanush, I was not aware of the gr-fcdproplus project; however, in practice, the only difference is really the 192k sampling rate of that audio device (I can't really see why the dl1ksv did not patch that functionality into gr-fcd, but that's completely his choice. It's easier, anyway, to

Hi, in pmt_to_python.py, there is the following function: def numpy_to_blob(p): p = p.view(np.uint8) b = pmt.make_blob(len(p)) pmt.blob_data(b)[:] = p return b What is the assumed input here? It doesn't seem to work with an ordinary 1D NumPy uint8 array. The pmt.make_blob()
