Hi,

I'm currently using Matlab to receive I/Q data by Simulink-Matlab-bladeRF repository https://github.com/Nuand/Simulink-MATLAB-bladeRF.
Bladerf_dev enables that scanning a frequency range and receiving enough I/Q data which I expect.

However, it takes a lot of time and must be boosted. At this point, it can be a good idea that modifying the bladeRF-cli's receive process. As far as I can see receiving process of bladeRF-cli is valid for a specific frequency. Is there any progress to receive and record samples from a specified frequency range i.e determining start-stop frequency and save csv/bin file? Or, is it possible to overcome this problem by any other way?

Thanks

Hi poi,

Perhaps one solution would be to write a script that launches the bladeRF-cli to change the frequency and read samples. Wrap that in a loop in your favorite scripting language.

I am assuming a Linux host here, but the sample applies to Windows:

Code: Select all

$ bladeRF-cli -e 'set frequency 910M; rx config file=/tmp/samples_910M.sc16q11 format=bin n=10M; rx start; rx wait;'
$ bladeRF-cli -e 'set frequency 911M; rx config file=/tmp/samples_911M.sc16q11 format=bin n=10M; rx start; rx wait;'
$ bladeRF-cli -e 'set frequency 912M; rx config file=/tmp/samples_912M.sc16q11 format=bin n=10M; rx start; rx wait;'
... and so on..

If this is too slow, it might be better just to write a simple C program to do this. This section of the API docs should help you here.

Best regards,
Jon

By the way, if you really need to retune quickly, this section of the API docs would be helpful. (Check out the quick-tune section.)
