Re: [Discuss-gnuradio] Problem with USRP B200

[James Humphries]

Hello,

Do you have multiple USRP's hooked up? If so, try only having one plugged in for this initial test.

You can provide a device hint in the arguments of the UHD source block. Try:

"type=b200"

As another test, make sure you can use the built in utilities of UHD to detect your USRP. 

uhd_usrp_probe

uhd_find_devices

You can also give a device hint like:

uhd_usrp_probe --args="type=b200"

Hi all,

i just started to work with GNU-Radio-Companion (v3.7.2). I finally got my USRP B200 connected and what im trying now is using the "UHD: USRP Source" block in grc to receive radio frequencies as a first step. Pretty easy stuff i guess.
I tried different things, but grc still comes up with the same Error:
"RuntimeError: ValueError: Could not resolve device hint "" to a single device."

Since i tried different things and it still doesn't work, i think there has to be a structural mistake. If someone could take a few seconds and tell me where the mistake is, i would be very grateful.

best regards!
