I'm using a vector-insert block to add a fixed-size header to a stream of interleaved short samples at a fixed interval, and then running it though
stream-to-tagged-stream => tagged-stream-to-PDU => Socket-PDU to wrap it up in a UDP packet and send it out the network. The header consists of 28 shorts, and the data of 512 shorts (actually 256 complex short samples), to yield a UDP packet payload of 540 shorts (1080 bytes). This works fine for the fixed fields in the header, but two of them are variable: Sequence-number and timestamp. Is there any convenient way from within GRC to insert an incrementing number into one of the shorts in the header? I know it can be done by writing a custom block, but is there any way to use existing blocks from within GRC? And what about the timestamp? Any easy way _within GRC_ to use and track the timetag from the USRP and the sample number to gen up a timestamp value for the header? @(^.^)@ Ed _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
