Unable to 'find' or 'probe' USRP x310

[RRathi]

Hello,

I am having some trouble with running USRP x310.

Initially, After assembling the hardware and installing the UHD drivers, I was able to run the experiments and everything was working fine, But after a few days when I tried to run it again I was getting "no rf-frontend found" error. So I tried to run "uhd_find_devices" and "uhd_usrp_probe" but both gave "No UHD Devices Found".

But for some reason I am still able to ping the Device from my host computer and also it is responding to " uhd_usrp_probe --args addr=192.168.10.2 ".

I tried to post the same question before with the outputs of all the commands but for some reason it was marked as spam.

Can someone please help me with this issue?

Thanks,

Raghav

Hello everyone,

I happened to find the solution to this problem. According to this post (https://stackoverflow.com/questions/33304828/when-trying-to-use-my-usrp-in-gnu-radio-i-get-a-no-devi...) I had to make the firewall accept the connection coming from x310 and this can be done using sudo iptables -A INPUT -p udp --sport 49152 -j ACCEPT
