Hello all,
I’m a “long time reader, first time poster” on this list, so bare with
me.
I have been trying to use m-blocks, at first just to send and receive
known signals.
For sending I just used the, in the svn rev 8687, provided
~/gnuradio/usrp/host/apps-inband/test_usrp_inband_tx, which works well,
I can see the sinusoid on the oscilloscope hooked up to my usrp.
The question I have is regarding the test_usrp_inband_rx.cc. In the
void “test_usrp_rx::handle_response_recv_raw_samples(pmt_t data)”-
function, I try to extract the data from v_samples, but I think I have
misunderstand how to use the “pmt_t” type. I tried looking at the wiki-
page for the pmt_t type, but still no luck.
As I have come to understand it, it should be possible to include a
gr_file_sink(…) into a mblock, but I don’t see how to do that, at
least not without using python (which I try to stay as far away from as
possible)…
Any comments, suggestions, clarifications would be appreciated.
Cheers
Mattias Kjellsson
