transmitRepeat function not found n MATLAB 2020a?

I want to transmit data using USRP B200 serial number F4F57E and i use transmitRepeat function but thats not found in MATLAB. is there any other function to use that.

You need to install the support package; https://www.mathworks.com/help/supportpkg/usrpembeddedseriesradio/ug/comm.sdrtxe3xx.transmitrepeat.html

I have already found that link. Can you guide me how to install support package?

Thanks in Advance

Thank you

[Faheem Ur Rehman]

I have install that support but the problem is same. I have attached two Picture please check it.

[Walter Roberson]

Unfortunately that support package is not available for Mac and I do not currently have Windows installed.

[Faheem Ur Rehman]

So whats the solution for this

[Walter Roberson]

Sorry, I am having a fair bit of difficulty getting my Windows emulation going.

C:\ProgramData\MATLAB\SupportPackages\R2020a\toolbox\shared\sdr\rfconverter_libiio\+comm\+libiio\+AD9361\tx.p is the file that implements transmitRepeat . It is a comm.SDRTxE3xx method . It becomes visible after you call sdrtx(); and is only visible when you pass the output of sdrtx into it.

I notice you are using a B200, but transmitRepeat is defined for E3* not for B2*

It is defined for: ADALM-Pluto Radio; USRP E310 or USRP E312 SDR, Xilinx® Zynq®-Based Radio

[Faheem Ur Rehman]

Yes you are right i am using B200. Is there any equivalent function for B200 to use it instead of transmitRepeat?

[Walter Roberson]

I do not know. I do not find an equivalent, but I do not know much about the package.

[Faheem Ur Rehman]

I have tried to find solution but not successfull. Can matlab community have some solution for my problem.

[Walter Roberson]

It appears to me that the hardware / software combination for the B200 does not support that feature with provided software.

Potentially it is something that could be programmed by sending a new image to the FPGA. It appears that you have about 3 megabits available https://files.ettus.com/volatility/volatility_USRP_B200_B210_r1.pdf

Hello, I would like to ask that you finally solved the problem that the function transmitRepeat cannot be used on B210

[Walter Roberson]

The company does not provide a system image for the B210 that supports transmitRepeat: you would have to program it yourself onto the FPGA.

[瑞婷 牛]

Hello, have you tried to implement this function on FPGA? Because I am not very familiar with FPGA, I hope you can help me

[Walter Roberson]

@瑞婷 牛

I have not done any software defined radio work, and I do not have any of the relevant equipment at all. I also have never generated FPGA for anything.
