I have a B210 USRP board. My application requires one receiver and two transmitter channels operating simultaneously.
The flow graph has one instance of USRP Sink block with number of channels configured to 2. The Subdev Spec is configured to "A:A A:B".
When I execute the flow graph, I get this runtime error as shown below.
I also tried creating two USRP Sink blocks with single channel each but one with Subdev Spec as A:A and other as A:B. That one doesn't have any runtime error, but I don't see the 2nd channel's Tx LED light up.
How do I configure the USRP sink blocks?
