I am trying to use two daughter boards in one USRP1. I have RFX400 on one side A and TVRX on side B.
When i try to use two seprate terminals to test the daughter cards in such a way that RFX400 is transmitting and TVRX is recieving on the same USRP1 device using uhd_fft and
benchmark_tx.py for sending data, but this does not work. when i run uhd_fft the scanning works but when i try to run benchmark_tx in another window, it gives some error tha can not find usrp device, how can i make it possible to work with both cards on the same device rather than using two different devices.
