SmartMesh IP motes running the default firmware in master mode terminate the On-Chip Application Protocol (OAP), documented in the SmartMesh IP Tools Guide.

OAP is a RESTful interface which allows your application to interact with the analog and digital interfaces of your SmartMesh IP motes.

This recipe shows you a Node-RED flow to interact with a mote in your network through a Node-RED Dashboard.

Import the Node-RED flow

Because it's a rather complex Node-RED flow, we maintain it as a GitHub Gist at https://gist.github.com/twatteynelinear/f2b132b3a3275b4983a3bc2d97dc893a.

As any Node-RED flow, import the flow.json string into Node-RED:

Open

Walk-Through of the Application

Connect to the manager

In the "setup" tab of the Dashboard:

1. Click on "list serial ports" and select the serial port which corresponds to the serial API of your manager. This will cause the JsonServer to connect to that serial port.

   Open

   

2. Click on "get status", the dashboard displays several statistics, and in particular confirms that the JsonServer is connected to the manager.

   Open

   

3. Click on "list motes" and select the MAC address of the mote you want to interact with:

   Open

   

   
   
   

Interact over OAP

The "OAP" tab gives you a clear overview of the OAP resources, and allows you to get/set their state and visualize the notifications.
