End Device AT Commands and Downlink

1. Introduction

Dragino LoRaWAN End Node support two types of AT Commands and 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.

2. How to use AT Commands or Downlink command

AT Command : See Devices User Manual for how to connect to device via USB TTL adapter and use. The user manual can be found in each product page of Dragino Products User Manual.
LoRaWAN Downlink Command: The gateway transfer downlink command in HEX format. This page shows the Downlink Command In HEX format. Please note some LoRaWAN servers use base64 as downlink code so user need to convert HEX to Base64 and use. Below are references for how to use downlink command: ** Use HEX format to send a downlink: TTN v3 ** Use Base64 format to send a downlink: Chirpstack, How to Convert? ** See use note for more serves Servers Note(IoT LoRaWAN Server)

AT+RX1WTO is theRxSingle timeout value of receive window 1. If it is not set, then the queriedvalue is the default value. If it is set, then the queried value is the setvalue. AT+RX2TWO is thesame as above. The definitionof RxSingle timeout is as described in the following paragraph.

Increasing thisvalue is equal to extending the time that the receiving window is opened, butthe corresponding power consumption will also increase. Properly increasingthis value can increase the success rate of the downlink.

Example: ~1. Set AT+RX1WTO=0, AT+RX1DL=5000, the window opening time is: 53.699ms

Set AT+RX1WTO=128, AT+RX1DL=5000, the window opening time is: 149.644ms

RPL value:

AT+RPL=0: Device won't immediately reply any downlink commands from platform.
AT+RPL=1: Device will immediately reply message to Unconfirmed Data Down. Payload is 0x00.
AT+RPL=2: Device will immediately reply message to Confirmed Data Down. Payload is 0x00 and requied response header for this command.
AT+RPL=3: Device will immediately reply message to MAC Command. Payload is 0x00 and requied response header for this command.
**AT+RPL=4: **Device will immediately reply message to Confirmed Data Down & MAC Command. Payload is 0x00 and requied response header for these two commands.

Case Analyes:

For Class A devices, AT+RPL=0 is ok. that is defaut settings in software.
For Class C devices used in ChirpStack, need to set AT+RPL=4 because Chirpstack require immedietely reply message to MAC Command.
For Class C devices used in TTI, need to set AT+RPL=4 because TTI require immediately reply message to Confirmed Data Down & MAC Command.

AT Command: AT+RPL

|AT+RPL=0|Set packet receiving response level|OK

Downlink Command: 0x21

Format: Command Code (0x21) followed by 1 bytes level value.

If the downlink payload=2101, it means set packet receiving response level to 1, while type code is 21.

Example 1: Downlink Payload: 2101 // set packet receiving response level to 1
Example 2: Downlink Payload: 2102 // set packet receiving response level to 2

1: uplink fcnt increase by 1 for each NBTrans. | 1

Downlink Command: 0x33

Format: Command Code (0x33) followed by 2 bytes mode value.

If the downlink payload=330100, it means set end node to use confirm mode, while type code is 33.

ACK_Timout_2: Unit: min

|Command Example|Function|Response | AT+DDETECT=1,1440,2880

value1 |Enable online detect| 1

| AT+DDETECT=1,?,2880

value2 |Online detection packet sending time|

| AT+DDETECT=1,1440,？

value3 |Process rejoin|

Downlink Command: 0x32

Format: Command Code (0x32) followed by 2 bytes mode value.

If the downlink payload=320105A00B40, it means set end node to use confirm mode, while type code is 32.

Example 1: Downlink Payload: 320105A00B40 // Set AT+DDETECT=1,1440,2880

** 0x01** : Flag**

     **0x05A0 **: ACK_Timout_1 : 1440minutes (24 hours)

     **0x0B40 **: ACK_Timout_2 : 2880minutes (48 hours)

Explain: Enable Online Detect, if end node doesn't receive any downlink within ACK_Timout_1( 1440 minutes or 24 hours). End node will use confirmed uplink to send packets during ACK_Timout_1 (the 24th hour) to ACK_Timout_2 ( the 48th hour). If from the 24th to 48th hour, end node got an downlink from server, it will switch back to unconfirmed uplink. end node will restart ACK_Timout_1. If from the 24th to 48th hour, end node still not got any downlink, means device doesn't get ACK from server within last 48 hours. Device will process rejoin, rejoin request interval is AT+RJTDC period. For AU915/ US915, device will use the sub-band used for last join.

7.26 Request the server to send an ACK

Feature: Mode for sending data for which acknowledgment was not received. LoraWAN Network Server(eg. The Things NetWork/ChirpStack/AWS/...).

AT Command: AT+PNACKMD

|Command Example|Function|Response |AT+PNACKMD=1|If the node uploads the ACK as confirm, it will request the LoraWAN Network Server to send an ACK. If the LoraWAN Network Server ack is not received, the node will upload the packets that have not received the ACK the next time it receives the ACK|1 OK

|AT+PNACKMD=0(Default)|off request the LoraWAN Network Server to send an ACK|

Downlink Command: 0x34

0X34 01 //Same As AT+PNACKMD=1

0x34 00 //Same As AT+PNACKMD=0

7.27 Adjust network rejoining interval

AT Command: AT+RJTDC

((( OK

the interval is 20 min

))) |AT+RJTDC=60|Set the ReJoin data transmission interval in min|OK Set the ReJoin data transmission interval to 60 min

Downlink Command: 0x26

Format: Command Code (0x26) followed by 2 bytes mode value.

If the downlink payload=26000A, it means set end node to use confirm mode, while type code is 26.

Example 1: Downlink Payload: 26000A // Set AT+RJTDC=10
**Example 2: **Downlink Payload: 260002 // Set AT+RJTDC=2

8. AT Commands Combination
