Downlink for LoRaWAN™

TagoIO will send downlink messages to your devices through Configuration Parameters. To enable this, create a key parameter named downlink and uncheck the switch labeled "Unread". Your LoRaWAN™ provider may allow additional downlink parameters.

warning

mportant: Most network servers require downlinks to be authenticated; otherwise they are denied access. If you're having problems sending downlinks, make sure you've correctly generated your authorization codes.

How it works​

To send downlink messages from TagoIO to your LoRaWAN™ provider:

  1. Go to your list of devices and select the desired device.
  2. Open the "Configuration Parameters" tab and edit or create a key parameter named downlink.
  3. Insert the downlink payload into the value of the parameter (the field on the right side).
  4. Make sure the downlink parameter's switch is unchecked (set to "Unread") so the platform will send it to the network server.

The downlink payload should be placed into the parameter's value field. Below is an example of the configuration screen showing the downlink parameter and where to enter the value.

info
  • Downlink messages can only be sent when the device sends an uplink message.
  • For Class C devices, you cannot rely on this automatic trigger; instead use the Downlinks using Dashboards article to send payloads manually.
  • The downlink payload may be expressed in base64 or HEX format; TagoIO will automatically convert it before sending.
  • After a successful transmission, the downlink parameter is marked as Read.
