I try to operate NI USRP-2920 by GNUradio. At the first, I typed "uhd_usrp_probe". Result is below.

In the next, I ran FM radio in GNURadio. Result is below.

[RuntimeError: LookupError: KeyError: No devices found for ----->
Device Address:
    192.168.10.4:

\[ERROR\] \[UHD\] Device discovery error: unknown key format: 192.168.10.4][1]

I can't understand this reason. Could you tell me any advices? Thank you.

Answer 1

I typed 192.168.10.4 in UHD:USRP Souurce block. It isn't correct. Type addr=192.168.10.4 in the block. i'm sorry to have caused trouble.
