Thanks, Alex.
I tried using the log files in benchmark_rx. But the file has 200 Megabit size and Matlab could not handle it. Can you limit the size of the recorded data?
Maybe you can add some control to start and stop the data recording, in your python code.
Besides, can you transmit bit level data using the benchmark_tx code? I can transmit '1', '2', 'a', etc. but I cannot transmit 1, 0. I assume that '1', '2', etc. are being transmitted as bytes. (I know that the digital_bert codes allow bit level processing but I wonder how I can transmit 0 and 1 using the benchmark_tx and rx codes, i.e., in a packetized format).
I never tried it yet. Why not just try to compose these bits to bytes and then feed to the physical layer? And why do you need to do that?
Thanks,
Nazmul

I just turn on the log and read the log files in Matlab.The intermediate signal processing results can be written into files.
Hope it help you.

Hello,
Can I transmit and receive bit level data using the benchmark_tx and rx codes of the narrowband/OFDM folder? At present, I can transmit and receive byte level data using the codes, i.e., I can put 1500 characters (or 1500 bytes) in each packet and receive it. But I want to transmit (i.e. 0 and 1 / -1 and +1) and receive the demodulated bits (not the bytes or characters). Can I do it using the benchmark or any other codes of gnuradio?
Any suggestion will be highly appreciated.
Thanks,
Nazmul
