[USRP-users] transmit and receive simultaneously at different frequencies with different rates with a single B210

Hey Guys,

I am looking to receive at one rate and transmit at another on different (
but nearby) frequencies with the same b210, with the tx and rx operating in
different threads.

I have seen examples of receiving on two different channels but not of
transmitting on one and receiving on the other?

Is the correct approach to initialize two subdevs

thread 1:
..
..
usrp1_->set_tx_subdev_spec(std::string("A:B"), 0);

and
thread 2:
..
..
usrp2_->set_rx_subdev_spec(std::string("A:A"), 0);
..

with a separate
uhd::usrp::multi_usrp::sptr usrp_;

initialized in each thread.


because this does not seem to work for me?

is there additional steps that i am leaving out or is there another way of
doing this?

Thanks!
Justin.
