How to Transmit Repeat with B200mini
显示 更早的评论
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.

Hello,
Starting with R2026a, we have introduced a new utility, transmitRepeat, in the Communication Toolbox for USRP radios. This utility enables you to continuously transmit data in the background while also allowing you to receive data using the same radio.
You can find the documentation for transmitRepeat here:
Additionally, the comm.SDRuTransmitter and comm.SDRuReceiver System objects now support running code in the background using MATLAB’s backgroundPool, or accelerating code execution with the Parallel Computing Toolbox™ ThreadPool.
With these enhancements, you can now transmit and receive simultaneously using the B200 mini radio. We have also verified this functionality by running image transmission and reception examples using both the LTE and WLAN, with a single USRP device.
Thank you,
Sreeja
