calibration fails in Matlab
Posted: Fri Dec 02, 2016 10:21 am
Hello,
I am using the burst mode transmission in Matlab (under Windows) between two bladeRF boards.
I am trying to calibrate from Matlab using the commands:
b.calibrate('ALL');
b.rx.corrections.auto_dc();
But when doing this, I see that the Rx systematically stops and the parameter act_count is always 14732. Do you know why this is happening? If I am not launching the calibration commands above, everything is fine.
Still from Matlab: I have noticed the same behavior even when I am not trying to calibrate: if I transmit a signal with alternating 0s and 1s (01010101 etc) at a sampling rate of 500 KHz, the Rx stops again, and act_count is always 14732. But if I transmit random 0's and 1's (so not alternating at every entry as before), everything is fine again.
Until now I used only the burst transmission mode (and the errors above came in this burst mode). Which brings me to another question: is there a way to transmit from Matlab continuously (streaming samples)?
Thank you very much for your help.
Best Regards,
Nicolae
