Hi,

I want to modify benchmark\_tx/rx.py for UHD

In benchmark\_tx.py,  
usrp\_receive\_path invokes rx\_callback when receiving a signal

I’m curious that it is also possible with uhd.usrp\_source or not

Oh, thank you very much

It seems its directory hierarchy is different from that of mine.  
I’m currently using 3.4.0

Is it new one for 3.5.0 ?
