Hi,
I wanted to ask you that if i want to send two independent data streams to
two daughter boards mounted on one usrp, wats the command for it.
If i want to explicitly send data1 to sub(0,0) and data 2 to subdev(0,1)
SIMULTANEOUSLY..then how do you do it?
I have read few examples but im not able to solve the issue. Here is the ref
code posted by Mr.Sungro
Yoon________________________________________________________________________________________________________________
self._pkt_input1 = gr.message_source(gr.sizeof_char, msgq_limit)
self._pkt_input2 = gr.message_source(gr.sizeof_char, msgq_limit)
intl = gr.interleave(gr.sizeof_char)
self.connect(self._pkt_input1, (intl, 0))
self.connect(self._pkt_input2, (intl, 1))
self.connect(intl, self)
self._u = usrp.sink_c (which=self._which,
nchan=2,
fusb_block_size=self._fusb_block_size,
fusb_nblocks=self._fusb_nblocks)
self._subdev = (self._u.db(0, 0), self._u.db(1, 0))
self._u.set_mux(0xba98)
self._subdev[0].set_gain(self._subdev[0].gain_range()[1]) #
set max Tx gain
self._subdev[1].set_gain(self._subdev[1].gain_range()[1]) #
set max Tx gain
self.set_freq(0, freq0)
self.set_freq(1, freq1)
self._subdev[0].set_enable(True) # enable
transmitter
self._subdev[1].set_enable(True) # enable
transmitter
self._dxc = self._which
self.connect(self, self._u)
_______________________________________________________________________________________
here you are simultaneously transmitting , but its one stream that both the
subdev are simultaneously transmitting.
In my case i have two independent streams.
Thanks in advance.
Regards,
Nadia
