I have created two copies of the usrp_spectrum_sense.py for wideband spectrum
sensing. Each one of them collects data from a different frequency band and
then finally fusion takes place.
I am invoking both the scripts from bash with a timer which make them
execute at the same instance of time.
Content of both the bash scripts are below (activate_usrp_1.sh &
activate_usrp_2.sh)
Only one application can have the USRP1 open at a time. There's no way to effectively "share" a USB device descriptor among different applications in Linux, and there are other reasons that's a bad idea as well.
