End Device AT Commands and Downlink Commands
Contents
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.
How to use AT Commands or Downlink command
See Devices User Manual for Device. The user manual can be found in each product page of Dragino Official Website
