NI USRP-2920 reconnu par GNURadio

Question

J'essaie d'utiliser NI USRP-2920 par GNUradio. Au début, j'ai tapé "uhd_usrp_probe". Le résultat est ci-dessous.

Dans le prochain, je courais la radio FM gnuradio. Le résultat est ci-dessous.

[RuntimeError: LookupError: KeyError: No devices found for ----->

Je ne peux pas comprendre cette raison. Pourriez-vous me donner des conseils? Merci.

Answer 1

J'ai tapé 192.168.10.4 dans le bloc UHD: USRP Souurce. Ce n'est pas correct. Tapez addr = 192.168.10.4 dans le bloc. Je suis désolé d'avoir causé des problèmes.
