Combine PDU message data with stream data

2021-11-19 Thread Barry Duggan
My objective: In reference to the https://wiki.gnuradio.org/index.php/Packet_Communications#Using_BPSK_with_Hardware_Simulation_.28version_3.9.29 tutorial: it sends packets but has dead time in-between, which may cause the BPSK receiver to lose sync. I would like to fill the time (and stream)

In this case, there is an extra bit of confusion because an empty PMT dictionary `pmt.make_dict()` is represented by (and the same as) `pmt.PMT_NIL`. An interned string, as in your first example, is not a dictionary type object and thus you get the warning message. Jacob ‐‐‐ Original

Re: Is there a Gnu Radio block to compute the power of a signal?
