Sorry for the delay.
I cannot see anything probelm from your grc graphs. It looks like you have already received signals from the transmitter. My suggestion is to check the parameters of packet decoder, GMSK demod, gain, etc. Hope you can sovle it.
Regards,
Jamie

Hi Jamie!
Thanks for your help, I tried trasmitting and receiving with the flowgraph attached and the result was the FFT after the UHD-USRP source FFT_after_UHD_source.png. However I didn't receive anything after the gmsk_demod. I don't know why but anything I can see.
If you can help me again, I really thank you.
Vivian.
