Adding a message formatter to a device instance

Adding a message formatter to a device instance

A message formatter can be added only to a smart sensor type based device instance using LoRaWan via LoRaWAN Datastream device connectivity. It is first added as a custom function of the Message Formatter type and then associated with the device.

To add a message formatter,
  1. Access the End Application.
  2. Select Devices > Devices in the left pane.



  3. Click on the name of the device for which you want to add the message formatter. This opens the device's information page. For this illustration, My Smart Sensor device is selected.



  4. Click Actions > Message Formatter and Handler.



  5. Click the Edit Uplink Message Formatter button.



  6. Click Associate Custom Function.



  7. Click Add Custom Function.



  8. Provide the details in the appropriate fields and click Save and Associate. This will open the custom function editor. For this illustration, a message formatter custom function called My Custom Message Formatter is created.



    Note: Display name will be the name of your custom function. Function name will be used for internal reference purposes.

  9. Provide the required custom function, in the Javascript Lite programming language, to format the received messages.
