Each group attaches its manager to the IBM Watson IoT Platform, forming a coordinated canopy network! |
|
The Setup
You will build the following setup, in which networks and applications are coordinated through the IBM Watson IoT Platform running on IBM Bluemix.

How the canopy network, which is already deployed in your building works. |
|
Deployment
The canopy network serves as a backbone for the low-power wireless mesh network you are deploying throughout your building. It consists of a number of SmartMesh IP managers connected to raspberry Pi single board computers, and a some DC9018 boars deployed on different floors of your building.

| different DC2274+raspberry Pi gateways are installed on different floors | a number of DC9018 provide coverage to the entire floors |

| Info |
|---|
The low-power wireless network in each floor is independent. They do, however, share the same netid. This means your mote can attach any of the networks. |
Networking Architecture of the Canopy Network
The following diagram shows the networking architecture of the canopy network: each gateway device is connected to the IBM Cloud, to which your Node-RED instance connects.

Why call it a "canopy" network? |
Building your Gateway
Ask away until you have a good understanding of how the canopy network is put together. |

Start the JsonServer
From Part 1: Your First Standalone Network, write down the fourth serial port of your manager. This is your manager's API port (not CLI):

Type the following command:

C:\Users\Thomas\Desktop\smartmeshsdk-master\app\JsonServer>python JsonServer.py --serialport=<your manager's API serial port> |
Configure Node-RED

A new tab "gateway" appears
| Note |

|
If Node-RED complains that it doesn't know what the "Watson IoT" node, you didn't install that extension. Go back to Things to prepare before the session. |

|
Your manager is now connected to the IBM Watson IoT Platform instance! This allows you to interact with your manager and motes entirely from there! |
Visualizing the Network Topology
- Open https://makeamesh.eu-gb.mybluemix.net/, i.e. the web front-end of the "makeamesh" server running on IBM Bluemix
- Once all groups have connected to the IBM Watson IoT Platform, you will see a topology similar to the following:

Walk around your building with a mote. On each floor there is a canopy network, switch on your mote and verify: - that it successfully joins network (look at the LEDs)
- that it appears on stars.solsystem.io
