Sending MAC Commands

End Device Status Answer (DevStatusAns)

The end device sends the DevStatusAns in response to the DevStatusReq command. The DevStatusReq command is sent by the network server to request the battery status and signal-to-noise ratio (SNR) for this DevStatusReq command.

The DevStatusAns includes the SNR and indicates whether the end device is currently connected to an external power source, reports the current battery level, or indicates if the battery level cannot be retrieved.

Learn more in Section 5.5, ‘End-Device Status’ (page 35) of the LoRaWAN® Link Layer Specification v1.0.4.
