Hello,
I'm currently having issues simultaneously transmitting and
receiving data from one B210 to another B210. My goal is to
send Tx data from one B210 and have it be received and re
transmitted from a second B210 back to the first. I am trying
to use both channels (RF A and RF B) to simultaneously
transmit and receive on both radios. To do this I have set the
"Mb0 Subdev Spec" to "A:A A:B" on both the USRP source and
sink blocks, as I have shown in the flowgraphs attached. My
radio can successfully transmit data from one B210 and have it
be received in the second B210. However, my issue arises when
my second B210 tries to re transmit the received data back to
the original B210 (This is shown if usrp_2_channel.png
flowgraph).
My question is, in order to accomplish successful Tx to Rx
loopback on both radios, do I need to label the Subdev spec
section as A:A A:B? Have I labeled the Subdev correctly for a
B210 or do I need to change it? Is it possible for a USRP to
transmit and receive simultaneously on both RFA and RFB
channels of a B210? If so, can I do this while using different
frequencies on each channel? Just for completeness I have
both radios connected to each other using coaxial cables with
a 38dB attenuation between each path.
Thanks,
Jose
