Hello, this is my first time posting a question:
I tried using the ofdm_tx and ofdm_rx examples with two USRP B200s, but even though I could see the ofdm spectrum on the receiver end, the time graph at the end of the demodulation was blank (straight line at 0) and I received the error
"gr::log :INFO: header_payload_demux0 - Parser returned #f
gr::log :INFO: packet_headerparser_b0 - Detected an invalid packet at item 6720"
