You have to open the PHY block. The pdu_to_tagged_stream block inserts a “pdu_length” tag. Later the burst_tagger block inserts tx_sob and tx_eob tags based on the pdu_length tag. You can use the tag_debug block to see where things go wrong. Also check the tag names in the blocks parameter. > > But If for example I try to use 0.5 as value (blocks.multiply_vcc(0.5)) I > got this error: > TypeError: in method 'multiply_cc_make', argument 1 of type 'size_t' I think you want something like blocks.multiply_const_vcc((.5,)) _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
