I narrowed down the problem to this: - In a standard benchmark_rx.py example from "digital" immediately after a packet is received the callback is triggered. - In the ofdm case the the callback is triggered in groups separated by one second. So, if a sender sends a bunch of packets they will be b

Hi, I'm using two USRP2 with XCVR2450s, gnuradio 3.2.2 and Ubuntu 9.10. I ran the benchmark_tx/rx example from gnuradio-examples/ofdm and measured packet inter-arrival times at the receiver. I also modified the sender to wait for some time (like 200ms) between individual packets. I also set the m
