I seem to have the gr-cdma OOT module installed and working properly. If on the TX side I create a vector source of 50 zeroes and then include a vector insert of the numbers 1-10, repeated every 10 times, I can see that coming through the receive chain, so I think I have a slight grasp of what is going on.
My question is that I wanted to send a small packet of data across (think hello world), but I am having trouble grasping how I would do that. I had originally setup a UDP source with a payload of 50 feeding into the throttle, but when I send a netcat over to it, I get an error because: gr::log :FATAL: crc32_bb0 - Missing a required length tag on port 0 at item #0 thread[thread-per-block[2]: <block crc32_bb (12)>]: Missing length tag. >>> Done (return code -9) I believe that this is due to the fact that I don't have a Tag crated in the UDP Source block. Has anyone send a custom message across? Am I missing something vital here? I am thinking ahead to an outside application creating a packet to send and needing to pass it to the GRC script. _______________________________________________ Discuss-gnuradio mailing list [email protected] https://lists.gnu.org/mailman/listinfo/discuss-gnuradio
