I have Ubuntu 16.04 and GNU radio version 3.7.10.1. I have two USRPs N210 with CBX daughterboard (1.2-6 GHz). My USRP is connected through the Ethernet cable directly to the computer
I am trying to send OFDM modulated data through the TX/RX antenna and I run uhd_fft to see the spectrum of the signal but whenever I start my transmission, the uhd_fft plot freezes and the runtime error:fifo ctrl timed out looking for acks appears on the terminal.
I have looked through previous mailing lists to find a solution but couldn't find anything useful. Can someone please tell me why is this happening and how can I fix this? Its very urgent for my project.
Thank you,
Best Regards,
Annie
