I am trying to demonstrate the FM Receiver using USRP B200 in GNU Radio; however, I always got an error message as follows:

RuntimeError: LookupError: KeyError: No devices found for ----->
Empty Device Address

Note that I can use uhd_find_dvices to successfully identify my B200.

Flowchart in gnuradio
