Hi,I am trying to write an application which senses spectrum (usrp_spectrum_sense.py) and transmits/receives signals. I have the tx/rx working fine. But when i add another flow graph(3rd one to existing tx and rx) for the spectrum sense,to the top block, it gives me an error. I get an error on this line which says "cant open rx interface" and "device busy"
self._u = usrp.source_c (self._which,
fusb_block_size=self._fusb_block_size,
fusb_nblocks=self._fusb_nblocks)
Is it because of competing receive paths. I thought that we could have
multiple paths.
Could somebody help in this regard. Sriram
