The *header* needs to be 32 bits. > 3.Is the packet length means that the original length(for example len=a) > or the length of data pass through CRC(len+4)? The header does not care what's in the payload (e.g. CRC). I recommend going through the ofdm_tx example to understand how packet lengths are set where. If you have specific questions about that, you can of course post them here.
