Thanks Eric... I will be more specific about the problem.... here it is... I am trying to combine the spectrum sense and ODFM Tx code together using multi flow graph concept. I idea is to sense the spectrum for occupancy and if free, use that frequency for OFDM transmission. So far I have achieved the connection between spectrum sense flow graph and the OFDM Tx flow graph. I am taking both the spectrum sense parameters and OFDM Tx parameters together at the time of initialization. The code is working fine performing the spectrum sense and ofdm transmission. But the frequency at which the OFDM transmission is happening is not at the frequency sensed to be free. Instead it is happening at the initialized frequency (--tx-freq parameter). I want this parameter to be changed at runtime. I have given following piece of code for the same:
