Hi Readers,
My PC has 2 gigabit ethernet controlers. I read data from USRP2 (UHD,
COMPLEX_FLOAT32, sample rate = 2.5 MHz) and sent it to another PC via UDP
protocol.
If I sent data to another PC directly (use IP address), in System Monitor
view : Receiving = 10.0 MiB/s; Sending = 19.6 MiB/s.
uhd_src = uhd_make_usrp_source(dev_addr,
uhd::io_type_t::COMPLEX_FLOAT32, 1);
uhd_src->set_center_freq(d_rf_freq,0);
uhd_src->set_samp_rate(2500000);
uhd_src->set_gain(20);
udp_dataSender = gr_make_udp_sink(sizeof(gr_complex),
"192.168.1.54", udp_port, 1472, true);
tb->connect(uhd_src, 0, udp_dataSender, 0);
If I sent data to another PC use broadcast address, in System Monitor
view : Receiving = 10.0 MiB/s; Sending = 1.2 MiB/s.
udp_dataSender = gr_make_udp_sink(sizeof(gr_complex),
"192.168.1.255", udp_port, 1472, true);
Could you demonstrate to me the issues, please?
Thanks.
LTP
