Status Request / Status Response

Messages of types status_request and status_response are intended to be used as information messages about device battery status and RF parameters.

Status messages are implementing LoRaWAN MAC-command DevStatusReq / DevStatusAns functionality.

To retrieve device status using DevStatusReq, you should perform the following steps:

  1. The AS sends a status_request message to the NS.
  2. The NS retrieves information from the device and sends it through a status_response message to the AS.

Let's walk through the sequence diagram to understand how the status message flow works:

This is what the sequence looks like:

  • The AS sends a status_request message to the NS.
  • The NS sends a downlink with DevStatusReq a MAC command to the device.
  • The NS receives an uplink with DevStatusAns a MAC command from the device.
  • The NS creates a status_response message for the AS and sends it.

Status Request

Status request - this is a message of type status_request, that was sent from the AS to the NS.


You should specify the following fields of status_request message metadata before sending it:

  • device - device identifier (dev_eui)
  • network - network identifier that this device belongs to

It is possible to specify a gateway as an option to ask the NS downlink optimization engine to use a specific gateway to send downlink message. If this gateway is not active, then the request will not be sent.


There are no parameters in this message.

Status Response

Status response - this is a message of type status_response, that is sent form the NS to the AS.
