Hi everyone, I was wondering if someone can point me in the right direction. I have an Adalm-Pluto and I wanted to run the FM receiver tets script but I got a bunch of errors. One of those errors was about changing the center frequency. I found a few videos on how to enable the 46MHz to 6GHz frequency spand and then I ran:
rx = sdrrx('Pluto')
rx.CenterFrequency=1.01e+08
rx =
comm.SDRRxPluto with properties:
Main
DeviceName: 'Pluto'
RadioID: 'usb:0'
CenterFrequency: 101000000
GainSource: 'AGC Slow Attack'
ChannelMapping: 1
BasebandSampleRate: 1000000
OutputDataType: 'int16'
SamplesPerFrame: 20000
EnableBurstMode: false
ShowAdvancedProperties: false
Show all properties
now I am getting this error but I can't find any info online on how to fix this:
Error using matlabshared.libiio.base/cstatus
Failed to update LO for device: cf-ad9361-lpc. Specified center frequency is outside factory
default range. To assign the center frequency to 101000000, release the radio and click
configurePlutoRadio('AD9364','usb:0'). For more information, see help configurePlutoRadio.

I did sucessfully installed the drivers and the libiio-0.23.gc14a0f8-Windows-setup. I also did a firmware upgrade using MATLAB
any information is apreciated. Thanks in advance!

In case someone has the same issue, I solved it by uninstalling the analog libiio-0.23.gc14a0f8-Windows-setup files and the communiations toolbox from Matlab. Then I had to reinstall the communications toolbox again, changed the Pluto to ad9364 (to enable the 46MHz to 6GHz) and comented out the "rcv = sigSrc();" from the FM sample script given my Matlab. the error went away and the pluto seems to be happy. PS: I am really new at this so try this fix at you own risk lol
