Introduction
Dragino LoRaWAN End Node support two types of 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 downlink command
See Devices User Manual.
Support End Node and firmware version
| Dragino STM32 base hardware Firmware / LoRaWAN stack list | ||
|---|---|---|
| Model | Description | Firmware Version ; Stack Version |
| LSN50-v1, LSN50-V2, | Open Source Generic LoRaWAN Sensor Node | LSN50 v1.6.0 <--> DR-LWS-003;
LSN50 v1.7.0 <--> DR-LWS-005; |
Common Downlink Commands
0x01 Change Uplink Interval
Format: Command Code (0x01) followed by 3 bytes time value.
If the downlink payload=0100003C, it means set the END Node’s Transmit Interval to 0x00003C=60(S), while type code is 01.
- Example 1: Downlink Payload: 0100001E // Set Transmit Interval (TDC) = 30 seconds
- Example 2: Downlink Payload: 0100003C // Set Transmit Interval (TDC) = 60 seconds
0x04 Reboot End Node
Format: Command Code (0x04) followed by FF.
If the downlink payload=04FF, the end node will reboot.
0x05 Enable/Disable Data Confirm Mode
Set end node to use confirm mode or unconfirm mode to uplink payload.
- Downlink Payload: 05000001, Set AT+CFM=1, use confirm mode to uplink.
- Downlink Payload: 05000000, set AT+CFM=0, use unconfirm mode to uplink.
