Re: [Discuss-gnuradio] UHD Error: recv packet demuxer unexpected sid

[Jorge Gallo]

Hello Marcus,

I am using 10MS/s. The use of 5MS/s or 2MS/s

 does not make any difference though.

If I just make a FFT of 20MS/s everything goes smoothly. I get errors only when reconfiguring the center frequency back and forth so I am suspicious that the sample rate is not the problem.

However I need those different center frequencies since I need to scan a large BW. What is the best approach to do that?

Many thanks for you support.

3.8.1 is quite recent; there's only the 3.8.2 Release Candidate that you
could update to, so this is good.

Possibly, but it often is.

I don't think that has anything to do with the problem at hand.

Still: which sampling rate are you using? Can you try with a lower one?
