How to Transmit Repeat with B200mini

Hey guys, im trying to transmit a signal via Ettus B200mini. My problem is how can i transmit my signal repeatedly? Is there any function like transmitRepeat() like with the Adalm Pluto SDR's?

Hi Jiyan,

I understand that you wish to transmit a signal repeatedly via "Ettus B200mini" and are looking for a function similar to "transmitRepeat".

Unfortunately, "transmitRepeat" supports only "E3xx" series radios and there aren't any similar functions available for "B200mini" radios. As a workaround you can use a while loop to continuosly transmit a signal.

Here is a code snippet for the same:

usrpRadio = comm.SDRuTransmitter('Platform', 'B200mini', 'IPAddress', '192.168.10.2');
usrpRadio.CenterFrequency = 2.4e9;
usrpRadio.Gain = 20;

txSig = randn(1, 10000);

while true
    usrpRadio(txSig.');
end

You can modify the while loop according to your use case.

I hope the above workaround resolves your query.

https://www.mathworks.com/matlabcentral/answers/773048-transmitrepeat-function-not-found-n-matlab-2020a#comment_1391907 had a previous discussion. The image for B200 just does not support the feature so you would need to customize the image.

Yes i solved the problem months ago with while loop but nevertheless thanks for your reply Nadia.
