I am facing a problem of random delay. I am using FMCOMMS5 + Xilinx ZC706 with GNU radio. I added FMCOMMS5 sink and FMCOMMS5 source in GNU radio and made a self-loop from the Tx to Rx. I clocked in my data stream from a file to FMCOMMS5 sink to transmit, and received the data stream from the FMCOMMS5 source. The Tx and Rx was connectors were connected. I compared the transmitted data and received data to monitor the delay. I found that every time I restarted the system, the delay changed.
I need to fix the delay from the FMCOMMS5 sink to source (self-loop) in GNU radio. Is there anybody knowing how I can make it?
Thanks for help!
