Sry for unethical reporting.
Mine purpose of pasting "010101" was to show that I am getting same data as transmitted while I was expecting some error because of
I am using:-
GMSK modulation and the code being used in benchmark_tx.py.
I have added the chanel_model block from gnuradio.filter before USRP sink in transmit path.py
As I am placing an artificial channel with multipath components I was expecting for some error in bits.
