I am currently having a problem with packet transmission similar to the
Tom R. had mentioned in his February 14th 2006 post titled ‘Dropped
Packets.’ However, there was no general resolution given there.
When I run the dbpsk/dqpsk/gmsk transmitter/receiver under the
gnuradio-examples directory (revision 4796), it always seems to drop the
packet, leading me to believe this hasn’t been fully fixed. Using
the --discontinuous option produces the same result. Even adding a
time.sleep(1) before fg.wait() doesn’t seem to fix it, as suggested by
To be sure that all of the data was being written out to USRP when
application, I put some print statements in usrp_basic_tx::write(), and
correct number of samples appear there (I can also verify that it is a
multiple of 128).
At the receiving end of my application, I can observe that the received
drops to the level of normal background noise somewhere before the final
packet is received.
I’m currently using the USRP (rev 4) with an RFX2400 daughtercard. I
set_auto_tr(True) on both transmitter and receiver.
Has anyone experienced or been able to resolve this?
