CLI scanner shows error or runs infinite loop, usb dongle heats up

[amane93]

Hello, i've found issues while running the command line scanner, so far there are two issues.

1. Running a scan shows "Error" and exits program.
2. Running scan goes into an infnite loop while heating up the rtl dongle.

Im not skilled at python but i was able to somewhat pinpoint where the error is happening
