hi, I want to use Rfx 400 and Rfx 2400 daughterboards on a usrp simultaneously to receive data from another usrp which has the same daughterboards. The transmit way use 2 daughterboard simultaneously is ok. but in receiving path i got nothing but gr.fr_fir_ff:using sse. it does not call the rx_callback function. I modified receive_path.py in these place: 1)usrp.source(nchan=2) 2)set.mux(0x32103210) 3)make 2 rx_callback functions 4)and many places must double to make two way receiving blocks my connect block is: self.packet_receiver0= \ blks2.demod_pkts(self._demod_class(**demod_kwargs), access_code=None, callback=self._rx0_callback, threshold=-1) self.packet_receiver1= \ blks2.demod_pkts(self._demod_class(**demod_kwargs), access_code=None, callback=self._rx1_callback, threshold=-1) ... di=gr.deinterleave(gr.sizeof_gr_complex) self.connect( self.u, di ) self.connect( (di,0), self.chan0_filt, self.packet_receiver0 ) self.connect( (di,1), self.chan1_filt, self.packet_receiver1 ) i have no idea which part is wrong. the transmit path i modified in the same method is working well. could anyone can help me? -- View this message in context: http://www.nabble.com/receiving-data-from-2-USRP-d...
