USRP Radio (R2013a) Burst Mode

When using N210 with the latest USRP radio package, I got some "uhd: U" errors, indicating that I cannot feed the USRP with data according to the required rate (determined by the sampling frequency and the interpolation factor).

Following the Matlab documentation I tried to use the "Enable Burst Mode" option in order to wait for data to accumulate and then send it to the USRP through the step function. Nevertheless, I am not sure how this feature works. It seems that at the beginning of the code execution, the USRP waits for data to be accumulated (but I can't figure out for how long), and then starts to transmit it in batches. Finally, I get an underflow msg indicating: "Could not execute UHD Driver Command in 'sendData_c"; libmwusrp_uhd_capi:tx_send_samples:ErrInternalUnderflow. There was underflow when performing a burst transmission".

Has anyone experienced with the "burst" mode and share his thoughts on this?

Many Thanks,

a.
