10 Dragino LoRaWAN End Node support two types of AT Commands and Downlink Commands:
11
12 * (% style="color:blue" %)**Common Commands:** (%%) They should be available for each sensor, such as: change uplink interval, reset device.
13 * (% style="color:blue" %)**Sensor Related Commands:** (%%) Only for special sensor, such as control relay, poll RS485 device.
14

16 **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.**

22
23
24 * **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 Official Website>>url:http://www.dragino.com/]]
25 * **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:
26 ** Use HEX format to send a downlink: [[TTN v3>>Notes for TTN]]
27 ** Use Base64 format to send a downlink: [[Chirpstack>>Notes for ChirpStack]], [[How to Convert>>http://wiki.dragino.com/xwiki/bin/view/Main/Notes%20for%20ChirpStack/#H4.1ConvertHEXtoBase64]]?
