Re: [Discuss-gnuradio] Not able to find USRP N310 in host mode

[Karthik Vasudeva]

I tried uhd_usrp_probe again but still the same problem. Please find the below error message

kvasude2@veneno:~$ uhd_usrp_probe --args addr=192.168.10.2
[INFO] [UHD] linux; GNU C++ version 7.4.0; Boost_106501; UHD_3.14.1.HEAD-0-g0347a6d8
Error: LookupError: KeyError: No devices found for ----->
Device Address:
    addr: 192.168.10.2

Also, find the below message from the embedded system showing the IP of the SFP0 port for the reference.

What if you use an explicit uhd_usrp_probe:

uhd_usrp_probe --args addr=<addressofsfp0>
