8 Dragino LoRaWAN End Node support two types of AT Commands and Downlink Commands:
9
10 * **Common Commands:** They should be available for each sensor, such as: change uplink interval, reset device.
11 * **Sensor Related Commands:** Only for special sensor, such as control relay, poll RS485 device.
12
13 (((
14 **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.**
15
16 )))
17
18 = 2. How to use AT Commands or Downlink command =
19
20 * For AT Command , See Devices User Manual for Device. The user manual can be found in each product page of [[Dragino Official Website>>url:http://www.dragino.com/]]
21 * 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:
22 ** Use HEX format to send a downlink: [[TTN v3>>doc:Main.Notes for TTN.WebHome]]
23 ** Use Base64 format to send a downlink: [[Chirpstack>>doc:Main.Notes for ChirpStack.WebHome]].
24 ** See use note for more serves [[Servers Note>>doc:Main.WebHome]](IoT LoRaWAN Server)
