Hi, I am using the usrp_wfm_rcv_nogui program to listen to FM radio. I have also added code to the program so that I can perform a scan, for stations in my area. My code works by first creating a usrp_source() for the FM code. When I want to scan for stations I press a button on my keyboard and then it stops the fm code from running by using tb.stop(). I then remove the flowgraph from tb so that the usrp source is not in use. The code then creates a new usrp_source() and scans frequency band. I then stop the scan code with scan.stop(). The code then does the same procedure as the FM code did to stop the source. When I return back to start the FM code again I get a RunTimeError: can't open usrp. I don't understand why I am getting this error if I have used the source once, stop that source, removed the source and then created a new one. Help is greatly appreciated. -- View this message in context: http://old.nabble.com/Usrp-Runtime-Error-tp29473867p29473867.html Sent from the GnuRadio mailing list archive at Nabble.com.
