Re: LimeSDR transmission issue

[Christophe Seguinot]

Hi

when dealing with real hardware:

• first is Hardware  weel configured (antennas, gains)
  
• then: is synchronysing required, generally yes, in the case of GMSK I don't know (may be  look at documentation if it need some differential coding)
  

Image of your flowgraph is only a little help, it's better to send .grc files.

Regards, Christophe

Hello, I have a problem with LimeSDR.  

Without Using LimeSDR, I am able to decode my data correctly. But once I add LimeSDR, my data completely becomes rubbish. I have tried to use a filter before GMSK demodulation, but it does not work.  Can someone tell me how to address this issue?
