How can I set mux for two daughterboards(rfx 400 and rfx 2400) receiving simultaneously?

I set:
usrp.source(nchan=2)
set.mux(0x32103210)
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 )

The self.packet_receiver0 and self.packet_receiver1 separately call two
functions.
But the two functions do not been called. What wrong did I make? Did I
set
the wrong mux? The daughterboards are rfx 400 and rfx 2400.

This appears to be the right mux setting.

With regard to whether or not your self.packet_receiver0 and 1 blocks
are calling some other function, I can’t really help. I assume that
their work methods are getting called. You can confirm this by adding
a printf.

Hi Eric,
The mux should be 0x2301, but not 0x3210.
It now works fine.

Dude, how do you calculate the Mux value you need?

For instance what’s the maths behind calculating the mux for two RFX2400
daughterboards?

Hi, I just try many times :frowning:
finaly I use a tool from a old version of grc called usrp probe, It gave
the
mux value of each daughterboard, so I just mix the two values.
I think the mux value for two rfx2400 should also be 0x2301
