Because OFDM related processes have not been optimized on E1xx, we intend to transmit a binary file which saves the result of OFDM benchmark_tx.py.
For debugging, it is useful to loop on a small binary file by
gr.file_source(gr.sizeof_gr_complex, options.from_file, True).
However, the same code works fine on general computer, but no transmission on E1xx (only transmit once, then no signal detected in the frequency domain, and no error message).
Is it because fseek() won't work on E1xx embedded system? Any one get it work?
