Gestione dispositivi Weave

Visualizza il codice sorgente su GitHub

Lo strumento weave-device-mgr (Weave Device Manager) funge da dispositivo di assistenza nell'ecosistema Weave. Gestisce l'accoppiamento dei dispositivi, incluso il provisioning della rete e dell'indotto. La funzionalità fornita è analoga al ruolo svolto dall'app Nest per il provisioning, l'accoppiamento e la registrazione di un dispositivo Nest al Servizio.

Weave Device Manager è incluso nella weave-tools build. In una compilazione dell'applicazione autonoma, si trova in /src/device-manager/python.

Esegui

Il menu di guida è disponibile durante il funzionamento dello strumento. Per avviare Weave Device Manager e visualizzare il menu di aiuto:

./weave-device-mgr
help

Connetti a un dispositivo fittizio

Poiché Weave Device Manager ha una funzione di assistenza, devi prima connetterlo a un dispositivo. Per testare questa funzionalità, utilizza una topologia simulata di Happy in cui un nodo esegue un dispositivo Weave simulato e un altro esegue Device Manager.

1. Creare una topologia Happy

In questa topologia, node01 eseguirà il dispositivo simulato, mentre node02 eseguirà Device Manager. Prima di iniziare, installa Happy e configuralo per il supporto di Weave.

Una volta installato, crea una semplice topologia Happy:

weave-state-load <path-to-openweave-core>/src/test-apps/happy/topologies/standalone/three_nodes_on_thread_weave.json

Controlla gli stati Happy e Weave per confermare la topologia:

happy-state
State Name:  happy

2. Avvia il dispositivo simulato

Accedi a node01:

happy-shell node01

In node01, visualizza un dispositivo simulato utilizzando l'indirizzo IPv6 Weave del nodo e un codice di accoppiamento Weave valido. È necessario un codice di accoppiamento per stabilire una sessione PASE sicura tra il dispositivo simulato e Device Manager:

3. Avvia Gestione dispositivi

Apri una nuova finestra del terminale e accedi a node02

happy-shell node02

In node02, avvia Gestione dispositivi:

./weave-device-mgr

4. Connettiti al dispositivo simulato

In Gestione dispositivi (node02), stabilisci una sessione PASE sicura con il dispositivo fittizio. Utilizza l'indirizzo IPv6 Weave e l'ID nodo del dispositivo simulato dall'output dei comandi happy-state e weave-state, insieme al codice di accoppiamento:
