Weave Device Manager

The weave-device-mgr (Weave Device Manager) tool serves as an assisting device in the Weave ecosystem. It manages device pairing, including network and fabric provisioning. The functionality it provides is analogous to the role the Nest app plays in provisioning, pairing, and registering a Nest device to the Service.

Weave Device Manager is included in the weave-tools build. In a Standalone application build, it is located at /src/device-manager/python.

Run

The help menu is available during tool operation. To start Weave Device Manager and view the help menu:

./weave-device-mgr
help

Connect to a mock device

Since Weave Device Manager serves an assisting function, you must first connect it to a device. To test this functionality, use a Happy simulated topology where one node runs a mock Weave device and another runs Device Manager.

1. Create a Happy topology

In this topology, node01 will run the mock device while node02 will run Device Manager. Before beginning, install Happy and configure it for Weave support.

Once installed, create a simple Happy topology:

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

Check the Happy and Weave states to confirm the topology:

happy-state

2. Start the mock device

happy-shell node01

In node01, bring up a mock device using that node's Weave IPv6 address and a valid Weave pairing code. A pairing code is required to establish a secure PASE session between the mock device and Device Manager:

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

3. Start Device Manager

Open a new terminal window and log in to node02

happy-shell node02

In node02, start Device Manager:

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

4. Connect to the mock device

In Device Manager (node02), establish a secure PASE session with the mock device. Use the mock device's Weave IPv6 address and Node ID from the output of the happy-state and weave-state commands, along with its pairing code:

connect fd00:0:fab1:6:1ab4:3000:0:4 18B4300000000004 --pairing-code AB713H

5. Test the connection

Send a Weave Echo request from Device Manager (node02) to the mock device to test the connection:

ping
WEAVE:DM: DataLength: 0, payload: 0, next: (nil)
WEAVE:EM: ec id: 1, AppState: 0x8d3777e0
WEAVE:EM: Msg sent 00000001:1 0 18B4300000000004 AFC0 986F 0 MsgId:00000000

Ping complete

Output on the mock device (node01) confirms the successful Echo:
