[Discuss-gnuradio] GNU Radio 3.7.12 RFNoC set_start_time()

2017-11-14 Thread Reggie Wilcox
Hello, I'm trying to use the set_start_time() command on a RFNoC: Radio block with a USRP X300. I am using the syntax to try to set the start time: self.uhd_rfnoc_streamer_radio_0.set_time_next_pps(uhd.time_spec(0)); self.uhd_rfnoc_streamer_radio_0.set_start_time(uhd.time_spec(15)); However, the

Yes just 1 minute after posting this mail I realized that hyphen in include guard is the root. I always created my own OOT, never added block in existing OOT, good learning for me ! I understood, the "make install" should place the public header in /include. Yes the CMakelist.txt was updated by t

[Discuss-gnuradio] TX and RX using same SDR

2017-11-14 Thread Ricardo Nuszkowski
Hello, We are about to receive our second antenna and want to test our GMSK modulation flow graph on gnuradio. We are just sending a text file so our TX flow graph looks like: file source—>packet encoder—> GMSK mod—>multiple constant—>osmocom sink. (I saw to add a multiply constant to not inter

[Discuss-gnuradio] Gnuradio clock coherence?

2017-11-14 Thread John Ackermann N8UR
What is the clock source for a Gnuradio "internal" source such as the Signal Source block? If there is no hardware device connected, is the block ultimately driven by the PC clock? Then, if there is a hardware source (SDR) as well as an internal source, does the hardware source provide the ma

[Discuss-gnuradio] Link error in _blocks_swig10.pyd

2017-11-14 Thread Gisle Vanem
I had trouble linking the _blocks_swig10.pyd block. (some missing '_imp_' symbols). So I investigated the ./gr-blocks/lib/ code and noticed there was a missing 'BLOCKS_API' for the classes in moving_average_XX_impl.h.t. This patch patch fixed it: --- a/gr-blocks/lib/moving_average_XX_impl.h.t 20

Hello, We will be running a basic flow graph to test our antenna with the LimeSDR. The flowgraph is basically an osmocom source--> WX GUI waterfall sink. It will run perfectly fine for some operations and then every once in a while we will run it and get this error. It then works fine after we h

Hello Ricardo Nuszkowski, The error messages are saying that it failed to initialize your radio hardware properly. It is either gr-osmosdr or SoapySDR (I think this is more likely), not really (the main tree) GNU Radio's fault. I recommend asking the same question on their mailing lists or forums

Unplug the power to the hardware and plug it back in - cold reset- see if happens again. It could be something as simple as not enough power if you're not using an external power supply. -- Cinaed On 11/14/2017 01:58 PM, Ricardo Nuszkowski wrote: > Hello, > > We will be running a basic flow gr
