Gerenciador de dispositivos do Weave

A ferramenta weave-device-mgr (Gerenciador de dispositivos Weave) serve como um dispositivo auxiliar no ecossistema do Weave. Ele gerencia o pareamento de dispositivos, incluindo o provisionamento de rede e de fabric. A funcionalidade fornecida é análoga à função do app Nest no provisionamento, pareamento e registro de um dispositivo Nest no Serviço.

O Weave Device Manager está incluído na build weave-tools. Em um build de aplicativo independente, ele está localizado em /src/device-manager/python.

Executar

O menu de ajuda fica disponível durante a operação da ferramenta. Para iniciar o Weave Device Manager e conferir o menu de ajuda:

./weave-device-mgr
help

Conectar a um dispositivo simulado

Como o Weave Device Manager tem uma função de assistência, primeiro é necessário conectá-lo a um dispositivo. Para testar essa funcionalidade, use uma topologia simulada feliz em que um nó executa um dispositivo simulado do Weave e outro executa o Device Manager.

1. Criar uma topologia Happy

Nessa topologia, node01 vai executar a simulação de dispositivo, enquanto node02 vai executar o Gerenciador de dispositivos. Antes de começar, instale o Happy e configure-o para oferecer suporte ao Weave.

Depois de instalar, crie uma topologia Happy simples:

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

Verifique os estados Happy e Weave para confirmar a topologia:

happy-state
State Name:  happy

NETWORKS   Name         Type   State                                     Prefixes

                                       2001:0db8:0001:0002:0200:00ff:fe00:0001/64

2. Iniciar o dispositivo simulado

Faça login em node01:

happy-shell node01

Em node01, mostre um dispositivo simulado usando o endereço IPv6 do Weave do nó e um código de pareamento válido do Weave. Um código de pareamento é necessário para estabelecer uma sessão PASE segura entre o dispositivo simulado e o Device Manager:

./mock-device --node-addr fd00:0:fab1:6:1ab4:3000:0:4 --pairing-code AB713H

3. Iniciar o Gerenciador de dispositivos

Abra uma nova janela do terminal e faça login em node02.

happy-shell node02

Em node02, inicie o Gerenciador de dispositivos:

./weave-device-mgr
WEAVE:ML: Binding general purpose IPv4 UDP endpoint to [::]:11095
WEAVE:IN: IPV6_PKTINFO: 92
WEAVE:ML: Listening on general purpose IPv4 UDP endpoint

4. Conecte-se ao dispositivo simulado

No Gerenciador de dispositivos (node02), estabeleça uma sessão segura de PASE com o dispositivo fictício. Use o endereço IPv6 e o ID do nó do Weave do dispositivo simulado na saída dos comandos happy-state e weave-state, junto com o código de pareamento:

connect fd00:0:fab1:6:1ab4:3000:0:4 18B4300000000004 --pairing-code AB713H
WEAVE:DM: Initiating connection to device

5. Testar a conexão

Envie uma solicitação Weave Echo do Device Manager (node02) para o dispositivo simulado para testar a conexão:

ping
