i will ask the devs of this tool for provision. maybe i have luck but can you just tell me how to determine the adress of the usrp to comunicate with it via cli? if it has nothing to do with the gps receiver, maybe its just a configuration failure. > > > _______________________________________________ > USRP-users mailing list -- usrp-users@lists.ettus.com > To unsubscribe send an email to usrp-users-le...@lists.ettus.com
