Hi, I've observed that all URB allocated in the Tx side are correctly proccesed. For example: Data -> 25 Byte (from a mpg file) Total payload -> 80 Byte (Data + CRC + Padding + Header + ....)
Total Byte to transfer with a BPSK modulator -> 80 * 8 (bit of a char) * 6 (sample per symbol) * 4 (Byte - IQ) -> 15360 Byte (multiple of 512 Byte). All URB buffers used are multiple of 512. In fusb_ephandle_linux::submit_urb (fusb_linux.cc) i have inserted wait_for_completion () function from which I get these massages: URB list empy (All request). I transmit such packets every 1 - 2 seconds (no stream data). But I can't see them on the Rx side using usrp_fft.py to observe the signal on the air. I can see some signal only occasionally. Is this problem reconducted to the Host PC side (maybe the Linux USB driver)? _______________________________________________ Discuss-gnuradio mailing list Discuss-gnuradio@gnu.org http://lists.gnu.org/mailman/listinfo/discuss-gnuradio
