Enable the D0 GPIO notification

This step enables the GPIO input pin. It is a required step for reading its value or activating notifications.

• create a flow which issues:

  • an HTTP PUT request

  • to URL http://127.0.0.1:8080/api/v1/oap/{{mote}}/digital_in/D0

  • with payload

    { sampleCount: 1, rate: 10000, enable: 1, dataFormat: 1 } 

• Open the SmartMesh IP Tools Guide (https://www.analog.com/media/en/technical-documentation/user-guides/smartmesh_ip_tools_guide.pdf), look for section "/digital_in". What does dataFormat 1 mean? 

Trigger D0 GPIO notifications

• Make sure you have a Node-RED flow enabled that listens to /oap notifications (see Lab 15. receive temperature )

• Connect a jumper between the DP2 and VSUPPLY pins. Make sure you receive a notification.

• Move the jumper to connect the DP2 and GND pins. Make sure you receive a notification.

• You can transition the jumper between the two positions above to generate further notifications.
