View source for End Device AT Commands and Downlink Commands

=Introduction=
Dragino LoRaWAN End Node support two types of AT Commands and Downlink Commands:
*<span CLASS=bluetext>Common Commands</span>: They should be available for each sensor, such as: change uplink interval, reset device.  
*<span CLASS=bluetext>Sensor Related Commands</span>: Only for special sensor, such as control relay, poll RS485 device. 

<span CLASS=redtext>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.</span>
<br>
<br>

=How to use AT Commands or Downlink command=
*For AT Command , See Devices User Manual for Device. The user manual can be found in each product page of [http://www.dragino.com/ Dragino Official Website]
*For LoRaWAN Downlink: The gateway transfer downlink command in HEX format. This page shows the HEX format downlink code for each command. but some servers use base64 as downlink code. Below are reference for how to use downlink command:
** Use HEX format to send a downlink: [[Notes_for_TTN#Send_Downlink_message|TTN v3]] 
** Use Base64 format to send a downlink: [[Notes_for_ChirpStack#Downlink|Chirpstack]].
** See use note for more serves [[Main_Page#Use_Note_for_Server|Servers Note]]

AT+RX1TWO 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.
[[File:RX1WTO.JPG|600px|none|thumb|]]
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.

==Set Packet Receiving Response Level==
Feature: Get or Set packet receiving response level. This feature is used to set compatible with different LoRaWAN servers. If RPL doesn;t match , user will see strange message in the server portal. 

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.
