Re: [Discuss-gnuradio] Asking USRP to tag

Hi Usman,

what information do you want these tags to contain?

Generally, this is not how the USRP source is supposed to work; tags are only added on certain events.

Best regards,

Marcus

Hi Marcus,

Sorry for being not clear. USRP source add tags on the first sample when the flowgraph starts. What can I do if I want USRP source to add tags again on any sample while the flowgraph is running? I read somewhere that there is a command for this but I do not remember. I am using N210 and X310. Thanks.

Hi Usman,

it's not clear what you actually want to do. The USRP doesn't add tags, tags are a GNU Radio concept, and added by the USRP source. Under which condition do you need a tag, attached to which sample, containing which data? Also, which USRP are you using?


Best regards,
Marcus

I want USRP to insert a new tag on the stream. I read earlier somewhere that it is possible now using some command. Can someone point to some example code ?
