Re: GNU Radio 3.9 OOT derived class
Indeed, that was the error. Now everything works fine. Thank you very much for your help.

Re: GNU Radio 3.9 OOT derived class
Hi Vasil, Thank you for your answer. Should not be Gnuradio "3.9" instead of "3.9"?. Anyway, I tried with both options and I got the same error: Target "TFMv3_python" links to target "gnuradio::gnuradio-digital" but the target was not found. Perhaps a find_package() call is missing for an IMPORTED target, or an ALIAS target is missing? What I changed was: 1 - Write *find_package(Gnuradio "3.9" REQUIRED COMPONENTS digital filter blocks analog fft)* in CMakeLists.txt 2 - Write t*arget_link_libraries(gnuradio-TFMv3 gnuradio::gnuradio-runtime gnuradio::gnuradio-digital* *gnuradio::gnuradio-blocks gnuradio::gnuradio-filter gnuradio::gnuradio-analog gnuradio::gnuradio-fft) *in lib/CMakeLists.txt As I've said, I tried with both "3.8" and "3.9" with the same output. I had to add filter blocks analog and fft as expected based on the explanation https://wiki.gnuradio.org/index.php/GNU_Radio_3.8_OOT_Module_Porting_Guide#GNU_Radio_Components El jue, 22 abr 2021 a las 17:13, Vasil Velichkov () escribió: > Hi Alvaro, > > On 22/04/2021 17.48, Alvaro Pendas Recondo wrote: > > 6.

GNU Radio 3.9 OOT derived class
Hello,
I am trying to implement my own header class derived from
'header_format_default' named 'header_format_counter_dif'. As you can
imagine, the class is quite similar to 'header_format_counter' with some
minor adjustments. My situation is almost identical to the one presented in
this mailing list before
https://lists.gnu.org/archive/html/discuss-gnuradio/2017-04/msg00063.html
However, the difference is that I am using GNU Radio 3.9, so in my case the
steps I have taken are
*Steps taken so far:*
1. Created my new module *TFMv3 *with gr_modtool
2. Added *header_format_counter_dif* (c++) using gr_modtool as type
'noblock'
3. Fleshed out the .cc and .h files based on the class
'header_format_counter' (but with some changes).
4. Made sure to *#include * in
the header file
5. Used *digital::header_format_default* as the parent class in the class
declaration since it's now in separate namespace to 'digital'
6. Add the line set(GR_REQUIRED_COMPONENTS RUNTIME DIGITAL) at
gr-TFMv3/CMakeLists.txt
6. Add the line py::module::import("gnuradio.digital") at python_bindings.cc
After that, I run *gr_modtool bind header_format_counter_dif *and I am able
to compile successfully. However, when importing TFMv3 I get the error
*undefined
symbol: _ZTIN2gr7digital21header_format_defaultE* which stand for *typeinfo
for gr::digital::header_format_default* (I found out using a C++ name
demangler).
So it seems I am missing something when including the mother class
correctly. Any ideas about what it might be?
Than you very much,
Álvaro
Header/Payload Demux Items per Symbol
Hello, I am implementing a packet communication based on the examples at gr-digital/examples/packet. Using packet-rx.grc as a reference with a single-carrier scenario, I am trying to change de "Output SPS" of the Poyphase Clock block from 1 to 2. That means two samples per symbol. I then set "Items per symbol" to 2 at the block Header/Payload Demux "Output Format" from "Symbols" to "Items" (following the example at ttps:// wiki.gnuradio.org/index.php/Header/Payload_Demux). However, when doing this, the output format changes and I get the error "Source IO size 16 does not match sink IO size 8" when connecting with the next step. I understand that now both samples are together in a vector as in the OFDM case. So I guess I need some kind of serializer to put the two samples back in a row. However, I have tried that with the block Vector to Stream unsuccessfully. Any suggestions? Thank you very much in advance, Álvaro
Library libbladeRF for bladeRF 2.0 micro xA4
Hello, I am considering buying an SDR model bladeRF 2.0 micro xA4 that is supposed to be compatible with GNU Radio through the library libbladeRF. Does anyone have previous experience handling this model with GNU Radio or other models by Nuand? I have experience with USRP and UHD, witch integration with GNU Radio is great, but I do not if that would be the case with libbladeRF. Any input would be greatly appreciated. Thank you in advance! Alvaro
