// Send the entire contents of the buffer

Hi again list, I am using the USRP 1 with a sampling rate of 250e3. I am trying to send a single burst that is 25000 samples long (100ms). The burst is a a complex sine wave with a fc=100e3 and fs=250e3. I use the following to send the burst. uhd::tx_metadata_t md; md.start_of_burst = true; md.end_of_burst = true; md.has_time_spec = false; // Send the entire contents of the buffer Int32 numSampsSent = m_pDev->send(&vec.front(), vec.size(), md,uhd::io_type_t::COMPLEX_FLOAT32, uhd::device::SEND_MODE_FULL_BUFF); My code tells me that numSampsSent is 25000. I have another USRP1 running grc that is using the scope and trigger mechanism. I send the bursts at 1 second intervals. On the scope, every burst looks like this: http://gergltd.com/delme/5.png to boot, I get a "U" printed to my terminal every time I send a message. Why would this be? I would think that sending a 0.1s message using the FULL_BUFF interface with nothing else going on with the USRP, that I should be able to to do this no problem and NOT drop any data. Hmmmm.... Any ideas? Im beggin'! Isaac
