Your problem might be that the transmitter outputs a tagged stream and, therefore, requires the Packet Pad 2 block as in the original flow graph. You replaced it with a block that expects a normal stream input that contains frames that are already marked with “tx_sob” and “tx_eob” tags. I would recommend to keep the original configuration.
