Hi, With gnuradio 3.6.3 I am using the gr_message_burst_source to
messages (one message per second) and set the bob and eob correctly.
this block I connect the following blocks to send bpsk modulated
: packet_to_unpacket_bb, map_bb, chuncks_to_symbol, rrc_filter and the
uhd_usrp_sink. However, I get many “U” characters in the screen, and
errors in the reception. I think that one or many blocks of the previous
ones do not propagate the tags properly. I appreciate any help to solve
this problem/question. Thank you.
Best regards, Pablo B…
