Hey everyone,
I'm trying to transmit from the TX/RX port of a USRP while receiving from RX2 but I'm getting a 'device already claimed' error message. Here are some details:
My USRP sink block uses multiple USRP addresses, i.e.
"addr0=192.168.1.2,addr1=192.168.2.2,addr3=192.168.3.2,..."
and each address goes to a different USRP in an array. I want to transmit a calibration tone across the array from the TX channel of the first USRP (addr0), but when I add a USRP source block it gives a 'device already claimed' message. This doesn't happen when I make individual USRP sink blocks for each USRP in the array.
Unfortunately if I separate my devices into several USRP sink blocks I can't guarantee the devices will be synched to the PPS. Is there a workaround for this?
