Introduction

Dragino LoRaWAN End Node support two types of Downlink Commands:

  • Common Commands: They should be available for each sensor, such as change uplink interval, reset device.
  • Sensor Related Commands: Only for special sensor, such as control relay, poll RS485 device.

This page shows the common commands since Dragino LoRaWAN stack DR-LWS-005. Make sure the end node support stack higher than DR-LWS-005 before checking this page.

How to use downlink command

See Devices User Manual.



Support End Node and firmware version

Dragino STM32 base hardware Firmware / LoRaWAN stack list
Model Description Firmware Version ; Stack Version
LSN50-v1, LSN50-V2, Open Source Generic LoRaWAN Sensor Node LSN50 v1.6.0 <--> DR-LWS-003;

LSN50 v1.7.0 <--> DR-LWS-005;



Common Downlink Commands


Downlink Commands List

Downlink Command Lists
Command Code Function Stack Version
0x01 Set LoRaWAN payload uplink interval DR-LWS-005
0x04 Reboot End Node DR-LWS-005
0x05 Enable/Disable Confirm Mode DR-LWS-005


0x01 Change Uplink Interval

Format: Command Code (0x01) followed by 3 bytes time value.

If the downlink payload=0100003C, it means set the END Node’s Transmit Interval to 0x00003C=60(S), while type code is 01.

  • Example 1: Downlink Payload: 0100001E // Set Transmit Interval (TDC) = 30 seconds
  • Example 2: Downlink Payload: 0100003C // Set Transmit Interval (TDC) = 60 seconds



0x04 Reboot End Node

Format: Command Code (0x04) followed by FF.

If the downlink payload=04FF, the end node will reboot.


0x05 Enable/Disable Data Confirm Mode

Set end node to use confirm mode or unconfirm mode to uplink payload.

  • Downlink Payload: 05000001, Set AT+CFM=1, use confirm mode to uplink.
  • Downlink Payload: 05000000, set AT+CFM=0, use unconfirm mode to uplink.
