Yes, I am interested in multiple bursts so Iam using the NUM_SAMP_AND_DONE
repeatedly.
If I understood what you've said correctly, hte following code may be
working. I havent tried it because I'm at home but would be grateful if you
tell me what you think of the modified code below.
Regards.
int work( int noutput_items, gr_vector_const_void_star &input_items,
gr_vector_void_star &output_items ){
set_streaming(true);
uhd::rx_metadata_t metadata; //not passed out of this block
int size = _dev->get_device()->recv(output_items, noutput_items,
metadata, type,
uhd::device::RECV_MODE_FULL_BUFF) ;
return size == 0 ? -1: size ;
}
protected:
uhd::usrp::mimo_usrp::sptr _dev;
const uhd::io_type_t _type;
bool _is_streaming;
void set_streaming(bool enb){
if (enb){
//setup a stream command that starts streaming slightly in the
future
uhd::stream_cmd_t
stream_cmd(uhd::stream_cmd_t::STREAM_MODE_NUM_SAMPS_AND_DONE);
stream_cmd.stream_now = false;
stream_cmd.num_samps=1000;
stream_cmd.time_spec = get_time_now() + uhd::time_spec_t(0.05);
_dev->issue_stream_cmd(stream_cmd);
}
else
_dev->issue_stream_cmd(uhd::stream_cmd_t::STREAM_MODE_STOP_CONTINUOUS);
// _is_streaming = enb; // REMOVED
}
};
