[Discuss-gnuradio] Dropped Packets

I am currently developing a BPSK transceiver with a fully-functional PHY and MAC layer defined in the GNU Radio/USRP. Everything almost works perfectly (the code will be released on our website once this final problem is solved), but I cannot get the final packet to receive correctly. Even when using the GMSK2 example, it seems like the final packet always messes up. When I take a closer look at the transmissions using our signal analyzer, I notice that the transmitter does not finish transmitting the final signal (it sends the preamble (I put this into the packet_utils.py for my synchronization loops), the access code, and part of the payload).


The problem seems to come from the thread handling the transmit procedure shutting down the USRP before the packet can be fully transmitted.


Any ideas?
