Re: [Discuss-gnuradio] Meaning of header_payload_demux0 - Parser returned #f

Hi Alex - If you want to share your GRC file with me (privately) and/or the list, we'll see what we can figure out. Guessing it's an OFDM sync issue, since GR's OFDM implementation is for async messages, and those are on a message by message basis. - MLD

Michael that provides insight into the error, unfortunately it does not explain the behavior of the example. The example uses the tx_packet and rx_packet hierarchical blocks. The output of the tx is routed to the input of the rx. I bypassed the example channel model and I’m not using hardware at the moment, so I would expect the example would have little issue with poor SNR and would maintain sync.
