Hi,
Thanks for reply!

That did not help. The problem is that in the file '' the code always checks
for the value:
if(result.checksum() != 558161692) {
dout << "checksum wrong -- dropping" << std::endl;
return;
}
I am not familiar with CRC. Why does it check always for 558161692?
Another important and strange thing is that in the transmitted frames CRC is
always different than the receiver side CRC value (I print them to see that).

I did not change anything in the flow graph: the message strobe is connected
with -> OFDM MAC block.
How can I activate frame detection? I thought that is by default. I run ofdm_rx
file usually. May that is the reason...

Not actually. I send BPSK 1/2 always. How can it be like this?

I will try. I go mad because of this does not work.
