I am using GNU Radio Companion version 3.6.2.
When I execute a simple flowgraph (containing two blocks: USRP Source
WX GUI FFT Sink), it generates the following error:
RuntimeError: LookupError: IndexError: multi_usrp: RX channel
out of range for configured RX frontends
Note that when I execute a flowgraph that does not deploy USRP, it works
Does anyone have an idea how to fix this error?
Any help is appreciated. Thank you.
