 On your computer, you will run both the JsonServer and Node-RED programs:

JsonServer

  • Double-click on smartmeshsdk\app\JsonServer\JsonServer.py. The application starts

  • The h command allows you to get a list of available commands

    > h
Available commands:
 - help (h): print this menu
 - info (i): information about this application
 - quit (q): quit this application
 - uptime (ut): how long this application has been running
 - status (s): get the current status of the application
 - seriaports (sp): list the available serialports
 - connectmanager (cm): connect to a manager's API serial port
 - disconnectmanager (dm): disconnect from a manager's API serial port
>

  • type "sp". What are the available serial ports on your computer?

Answer 1:

  • using the "cm" command, connect the JsonServer to your manager's API port

    • the API serial port to connect to is the 4th one

    • so if command “sp” returns COM3, COM4, COM5, COM6, you need to connect to COM6

  • type "s". Verify the manager appears as "connected".

Node-RED

  • in a command prompt, start Node-RED by typing

    C:\Users\twatteyne>node-red
